Version Build Date (dd/mm/yy)	Changes
2024.6.7 23/12/24	Some optimisations, bug fixes and tweaks to further stabilise this years build. Made a change that allows MysticThumbs context menus to be used in DirectoryOpus, albeit with limited scope and application. Can use to spawn QuickView windows or the control panel from within DOpus. Fixed an issue with custom extension icons where the chosen icon/image was no longer found. If this is now the case, a warning icon is shown/used instead so the user can remedy the problem. Less intrusive tooltips when hovering over choose icon dialog icons, and added tooltip text for the index of the hot icon for reference.
2024.6.6 16/12/24	As we begin to close out the year, the focus has been on fixing some performance issues and tidying things up. Performance improvements to property system that was causing long system locking issues. Fixed some issues with postscript based files not reporting correct sizes depending on their file units. Should result in better thumbnails and QuickView imaging. Very significant performance improvements to PDF / Postscript file reading and rendering. Fixed potential crash in Blocked Folders dialog when removing folders. Improved properties fetch and rendering for DSO based file formats (Office Document, Publisher, 3ds Max, Kubotek). Fixed some image formats with files > 8 bit depth such as DICOM Medical Images. QuickView resizing and clamping improved. Updated recommended GhostScipt version to 10.04.0. If you want the latest recommended Ghostscript, uninstall both 32 and 64 bit versions using the Add/Remove programs control panel before updating / installing.
2024.6.5 10/12/24	Fixed crash with thin images such as one pixel high, in both thumbnails and QuickView.
2024.6.4 05/12/24	Fixed .PES Embroidery files that have been not working for some time. Fixed momentarily unresponsive QuickView when background checking for updates. Created a new "Windows Imaging Component" file format so you can add extensions to other WIC components you have installed to control them with MysticThumbs. Updated requirements tooltip information on High Efficiency Image for more detail on possible codec solutions. Improved tooltip for maintenance expired link in control panel.
2024.6.3 27/11/24	This version includes incremental updates from previous beta and release candidates. 2024.6.3 Fixes to how icons are fetched based on if they are UWP apps or not. Default file association icons were a bit mangled in the past few versions. 2024.6.2 Added context menu item 'Restore Depth' when file(s) have a non-default depth buffer state set. Improved energy efficiency of control panel by removing a regular poll not required. Maya IFF files with a depth buffer now refresh correctly when toggling the depth buffer in QuickView. Using the context menu in QuickView could lead to losing keyboard input, requiring switching to and from another application. Refresh open folders sometimes didn't work when applying changes. Adornment button option is always able to be toggled now, even if a file format / extension is disabled. 2024.6.1 Includes changes from previous pulled version 2024.5.0 and previous beta versions. Fixes for Maya IFF files. Fixes and improvements to Amiga images including best correct for hires / lace modes for aspect ratio, better support for HAM and SHAM images. Choose icon dialog changing file may have caused a crash when selecting an icon file after a DLL file. If using choose icon to select an override UWP PNG icon, now detects if there is a 256 size version to use as the override icon to avoid small icons being used. Fixed image of icon overlay and show icon overlay buttons when double clicking to open the choose icon dialog so they show the state of the button before the double click. Where file extensions do not have a perceived type, register as perceived image so folders containing mostly supported files automatically open in thumbnail view by default. When selecting override icon button first time, get only the extension icon path first, then app icon unless an extension icon doesn't exist. Further improvement in override icon overlays working on some file types. Better guards around thumbnails for PNG for Metro/AppStore apps icons. PNG, JPEG and GIF are now enabled by default due to changes in thumbnail and icon interplay. Choose icon dialog better selects files when browsing for a new icon (library) file. Choose icon dialog, now remaps icon id's to the associated icon index. Fixed following of registry to correct current version of applications for extensions for registering thumbnail and icon handlers. Disabled darken animation since for UX performance. Some files with quoted or decorated paths did not open in the choose icon dialog. Further improvements to make icons and thumbnails generate and fetch when required. Changed choose icon dialog size to have 10 icons wide by default for easier counting if looking for a specific index. Fix for trying to set 'Unknown' file type icons, causing icon errors system wide. App store apps could lose icons on taskbar etc. Fix for extremely large text / richtext files causing crash. Fixed not retrieving correct icon for actual .ico file references, causing some issues with icon matching. SVG images was being overlaid onto document icon. regression from 2024.5.0. Improvements to file extension registration -> better handling of file extensions that have changed user choice / Open With application. Context menu was not being registered to open correctly. Regression from 2024.4.1. Double clicking theme dialog transparency button was not opening options for canvas or checkerboard selection.
2024.5.0 19/09/24	This version has been removed due to a bug affecting some users with icons disappearing / not correct. It has now been integrated into version 2024.6.1. This major version includes an overhaul to the help system (user guide) and documentation and a new 'Tip of the day' control panel option. Pressing F1 on a control now accurately takes you to the correct place in the help for a faster reference. Local help is now opened in your default browser application. New help system using a local web server instead compiled help. Local help is now the default option. Context menu might not have opened when in collapsed mode. Regression from 2024.4.1. Web based files now render to a filepage icon in thumbnail mode for consistency with other document type files such as text. Improved the behaviour of restarting Explorer. Added new feature 'Tip of the day' that will show a random tutorial tip when opening the control panel. Improved show/hide on some controls when starting / stopping tutorial mode. Updated tutorial text for global context menu option to reflect recent changes. Updated control panel local/online help to better reflect current version. Updated credits / hints. Prevent control panel modifier keys when a dialog / drop list is open. Control panel logo animation stops after a few minutes to save energy. Updated some translations that didn't fit on controls in all languages. Removed unneeded timer from QuickView to help save energy.
2024.4.2 19/08/24	Note, an early release of this version would have shown an error 'a newer version is installed' when updating. This has been corrected. Minor update to correct some rendering issues with small icons. Small icons for Text and RichText were not rendered correctly on a page icon. Small icons for Web and Web Aggregate formats updated to render on a page icon.
2024.4.1 17/08/24	Added RichText file format (.rtf). The new RichText renderer is now used for the Text format to achieve a more consistent overall image and better performance. This may introduce some unexpected visual changes from prior releases. Global context menu option changed so there is no disable option. Instead use the 'requires shift key' option (changed by double clicking the button). Some improvements to the credits screen. Various other bug fixes and tweaks.
2024.4.0 03/08/24	Added requirements information icon ⚠ to file formats that may require specific installed system applications or WIC image plugins, as well as tooltip information that details the requirements. Added credits window ability to pause (with P) and scroll with mouse wheel or up/down arrows to read credits/info/license texts. Credits window now has pages and web hyperlinks to navigate information and external links. Credits window now has inertia scrolling when paused and using the mouse wheel / up / down arrow keys (hold [Ctrl] to accelerate). Updated the credits help key ([Ctrl], [Alt], [Shift]) graphics for better clarity. Updated credits license informations. Changes and additions to RAW metadata / EXIF handling. Improved performance of property system to help display File Explorer thumbnails faster when in details mode.
2024.3.2 26/06/24	Regression in 2024.3.1 that caused a crash with files not correctly registered. Made heif format require an external WIC plugin. See the app store or elsewhere if you require one.
2024.3.1 21/06/24	Build removed due to crashing bug. Fixed in 2024.3.2. Some file overrides using full thumbnail and transparency modes were not working correctly. Draw color on dynamic images such as ABR when in transparent mode, drawing on checkerboard / full thumbnail canvas colors choosing between dark and light pens. Fixed refreshing QuickView when changing canvas or checkerboard colors on transparent images. Restoring all settings from .mtsettings file didn't update the control panel state properly.
2024.3.0 20/04/24	Added .dotx to Open Office formats. Added a new custom installer/uninstaller/updater procedure that asks the user to close any applications that have MysticThumbs core files open to try to prevent auto-closing / losing any work. This should help prevent unintentional loss of work if you happen to have an app open that is using MysticThumbs in open/save dialogs when installing updates or uninstalling for example. Core performance optimizations. 'QuickView' renamed to 'Quick View' for translation purposes in texts / messages. Changed the way the installer works to prevent spawning tray app / Quick View elevated on installation / update. Tweaked and added information to the about window / hints page for expert users to learn from. Clear thumbnail cache from the tray icon context menu now doesn't need to spawn the control panel to perform the task. Therefore it's now much faster. Language in context menus sometimes changed after control panel Apply incorrectly. Some work on displaying a wait cursor more appropriately when doing work in the control panel. Some icons were not displaying correctly in tooltips. Regression 2024.1.1. An optimization to make the control panel search extensions dialog appear slightly faster causing internal state corruption with the file formats and many potential resulting bad bugs including control panel crash. Reverted change. You can now use [Ctrl]+F to search for a file extension in the control panel. Explorer crash when selecting folders with a period '.' in their name. This bug may have also malfunctioned a number of other things. Regression introduced in 2024.1.1 - Interim fix for some users applications reporting false read-only files, preventing the user to save files. Reverted property handler back to 2024.1.1 whilst we investigate the issue. Wait cursor showing more appropriately with open modal dialog boxes. Exporting file extension settings was showing a failure when it succeeded. About window F1 to toggle hints wasn't working. Crash when encountering .ico and possibly other files handled partially by system codecs. Regression from build 2024.1.1. Full size thumbnails were not aligning properly. When applying changes in the control panel, sometimes open QuickView windows didn't update accordingly. Regression - sample and scale mode options were not working in the context menus. Under some circumstances the chosen dark mode was not applied to the running tasks dialog. Fixed running tasks dialog sometimes staying open for a time after all tasks were complete. Possible race condition crash when shell tried to clean up our shell extension with the running tasks dialog open. Fixed bad "current version is newer than chosen version" error showing when installing a final after beta. Fixed potential hang / crash when loaded from Explorer shell DLL and unloaded. Removed QuickView maximum resizing limit that caused aspect clamping issues. QuickView window resizing scaling / aspect ratios improved. Postscript QuickView scaling improved. Reworked some property store cleanup code to prevent a potential hung thread. Added some extra hints for PDF ghostscript decoding in an attempt to increase performance for some files. Improved property store calls with a short duration cache to try improve multiple fetches to slow ping images. * Edit File Extensions Enhancement * Beta - You can now edit file extensions for file types by opening the file extension box and selecting the '...' ellipsis item at the bottom of the extension list. - This allows you to add or remove extensions for file formats and can be useful to add support for extensions that aren't listed by default under a certain file format. - For example, you could add extra text based file extensions to the 'Text' file format such as programming language source files, or XML based file extensions that you would like visualized to the XML file format. - Use with caution. This feature is currently considered BETA but performs as expected in tests so far. Use knowing this, and only use if you are certain of what you are doing as there could be unintended side effects if a file extension was connected to another shell extension. - Be careful adding extensions for file formats that it may not properly support. It's possible you may experience a crash. If that happens, simply remove the extension again and if you believe it should work, contact support with a sample file so we can investigate.
2024.1.1 22/02/24	Fixes a bug with 2024.1.0 that caused control panel to crash when starting up on some systems. This version replaces that version. Some support for JPEG PDF's added for things like document scans. Added hotkey/button [Shift]+[F10] to take a capture of the control panel window. Added a snapshot the control panel to cilpboard button. [Shift]+[F10] or [Shift]+press the revealed snapshot button. Maya file type renamed to Maya (Swatches) for clarity since a .mayaSwatches folder is required to thumbnail them. Improved general rendering performance and memory usage of control panel. Some translations with dynamic text didn't add in whitespace. This has been improved. Improved QuickView gamma slider performance for much faster feedback. Massively improved refreshing open QuickView windows when modifying the control panel settings. Improved scaling and refreshing of QuickView. Improved QuickView redraw of some vector based formats after scaling. Improved copy to clipboard functionality. Added copy to clipboard formats in the advanced settings dialog, found in the Convert to format context menu settings. Improved some language/localization formatting. Improved maximum file size checks to prevent thumbnailing files too large when set. Changed all file formats with default transparency mode checkerboard to default transparent as it's probably more useful to the average user. Existing settings will not be affected. Fixed nag reminder to register whilst in evaluation mode less often. After clearing the thumbnail/icon cache, open Explorer windows are now automatically refreshed. Control panel crash when starting up on some systems. Some potential issues with non-English languages. Potential crash when closing control panel. Scale up / Full size button revert function wasn't quite right in all file formats mode. Saving the control panel capture for a support request was not working. Regression when holding [Ctrl] key to restore to defaults, the default state was shown instead of the current state. Choose icon dialog, fixed copy/paste icon so the correct icon file and icon are highlighted in the dialog after a paste. QuickView copy to clipboard bug fixed. Convert to format settings dialog text and translations. Context menu sometimes didn't populate MysticThumbs items from desktop. Some Chinese and Japanese texts were not displaying correctly.
2024.0.3 21/01/24	Major Update, 2024 version Packed full of Quality of Life improvements, new features, optimisations and bug fixes that have been in development for four months and are aimed to please. Please read through the change list so you know what to expect if you are updating, especially with major functional changes. Added .psdt - Photoshop template files - to Photoshop file extensions. Added VinylMaster .vDoc file format. 'All file formats' mode states are now remembered. Added light/dark mode theme button to the theme editor so you can see icons in the respective mode. When using the context menu on a Windows Explorer item to modify states or refresh, or using the control panel 'Refresh Open Explorer Windows' global mode and applying changes, there is now a progress dialog that will show after a second to allow you to monitor the changes taking place and optionally cancel the operation(s) if desired. This can be especially useful if applying changes recursively. Checkerboard dialog is now resizable. Improved checkerboard dialog buttons images and states to better reflect the overall state. When changing languages, theme and blocked dialogs are updated. Improved theme dialog icon tooltips. Registration, plugin, proxy, update, download dialogs are centered again on the control panel main window when opened. Improved control panel novice/expert button. Some tooltips updated for better clarity. Choose color dialog now only responds to a double click on appropriate controls. Reset icon and cursor file types to default to cubic sampling to keep consistency in 'All file formats' mode. Improved display of control panel type (novice expert) button to show when debug logging is enabled, in case the user forgets. Performance and Gamma buttons rendering. Theme editor now supports canvas color viewing mode. It also supports changing the canvas and checkerboard colors. When using [Ctrl]+Apply to refresh open folders, the current 'Apply to Mode' is respected so that you can choose to refresh only a specific file format, or a specific file extension, or everything. Improved checkerboard select dialog outlines on the preset list for dark and light modes. Changed the way multiple states are shown in novice mode on buttons when in apply to all or format mode. Now the state of the underlying extension or all format mode is shown and an asterisk * is added to show multiple states. This brings a little more clarity to state setting in multi-modes. Improved postscript based QuickView rendering. Performance, when using the context menu to modify files/folders, a better check is now in place to skip files not supporting modification of unsupported functions such as transparency & full thumbnail etc. Refreshed many icons for a bit better clarity. Apply to open folders can now also apply to desktop icons, however desktop folders will not be recursed if the recurse folders option is enabled unless they are open in an Explorer window. Various performance optimization and tweaks. Changed Krita to default checkerboard transparency. Changed PDF default non-premultiplied alpha. Selecting 'Clear thumbnail cache' from the control panel or quickview jumplist now opens the (now standardized throughout) clear thumbnail cache dialog box. File types that don't support transparency had the transparency button disabled. The button is now enabled if the file type supports full thumbnail mode so you can choose canvas and checkerboard colors. These file types will only toggle between canvas and checkerboard for the purpose of being able to choose those colors. When changing dark mode, open dialogs are updated to the new mode. There was a problem saving some dialogs positions / sizes correctly. Theme dialog icon path was not visible. Choosing a custom icon was not displaying correctly for file extensions. Selecting file extension from the search loupe did not correctly save the currently selected file extension for the file format. Icon overlay buttons were not showing the correct state text or overlay icons for multi-states. Disabling Show association icon did not work unless a custom icon was enabled. Rendering control panel buttons with text was not drawing the text in beta 4 due to an optimization. Toggling debug logging when having skip dialog without [Shift] pressed didn't work correctly. Toggling small icons may not have updated the button icon properly. Some control panel memory leaks. Entering an old license key into new versions of the control panel would ignore the key entry and do nothing. Control panel state buttons may have been in an incorrect state after restoring defaults button. Fix potential crash on control panel cleanup. Setting adornment for some file types wasn't taking effect. Buttons did not show the correct 'modified from default state' icon in apply to file format mode. When a file extension has small icons enabled, the control panel icon was appearing as a generic blank sheet of paper icon instead of either the associated application icon or the override icon if applicable. Fixed taskbar jumplist icons. Potential crash fixed when logging some strings. Postscript / illustrator checks for supporting rendering full image or fallback to embedded thumb fixed. Postscript / illustrator better heuristic to discern width / height for image properties to correct resolution / dpi. Bug decoding some SKP files. Regression from 2023.3.0. Improved refreshing open folders and recursing into sub-folders when enabled improved is better managed. Handling of refreshing thumbnails on the desktop improved including refreshing transparency and other settings. Postscript files specifying inches/cm are scaled accordingly where possible. Some postscript files would try to render too large due to xmp metadata not in pixels. Fixed occasional occurance of temporary files being created where they shouldn't have. When creating small icons, if transparency is checkerboard, it is treated as canvas color instead.
2023.4.2 23/08/23	Tutorial tooltips now render with DPI scaled icons the same as regular tooltips. Bad handling of dialog boxes when entering license key in Admin mode. WebP now supports animated images using the page context menus. WebP no longer requires an installed WIC codec. Windows Metafile images are now procedural in QuickView so they refresh when scaled and support vector imaging. Improvements to sizing QuickView windows from the corners. QuickView window not opening to the correct size of some images.
2023.4.1 10/08/23	Windows Metafile reworked to used Direct2D decoders. Gdiplus dependencies removed. Control panel 'About' feature F1 help updated with option key button variants.
2023.4.0 03/08/23	Added Convert to... BMP, DDS, GIF, JPG for more flexibility with common file types. The context menu items are also sorted by extension name. Export / Import file format settings function for sharing file type settings with other machines/people. - To export settings, select 'All Formats' mode, hold [Alt] and press the Export button which replaces the Undo button. Saves a .mtsettings file to the user's Downloads folder. - To import settings, hold [Alt]+[Shift] and press the import button which replaces the Undo button and choose the file to import. Hyperlink buttons were not responding to button clicks. Regression from 2023.3.0. QuickView image scale is kept when moving between files or changing modes such as metadata transform/rotation. When moving between files in QuickView using Explorer or the cursor keys, the new file's settings are loaded. They used to be kept from the current QuickView settings. This behaviour was not ideal. QuickView context menu - apply changes to file - was not applying metadata transforms back to the file. Windows Bitmap (.bmp) file type now defaults to non-premultiplied alpha for consistency. Convert to ICO icon file now also saves a 256 size icon. Memory leak when filling control panel combo boxes. Scaled up tooltip icons on HiDPI displays. Improved visual fidelity of tooltip icons. Fixed size of language combo button, was slightly too long for non-HiDPI. Fixed bug when refreshing open folders could cause refreshing of other items and lagging tray / QuickView app. QuickView windows were not showing in the taskbar. Fixed a long standing bug with QuickView sometimes opening with a blank window, requiring a refresh. QuickView: when changing embedded thumbnail options the image is reloaded and resized to adjust accordingly. Pressing [Space] to open QuickView now opens all selected items in the Explorer window.
2023.3.4 26/07/23	Improved performance of DirectX images. Fixed some issues with QuickView painting transparent images and repainting in general. Improved QuickView window erasing / painting for dark mode and various other scenarios. Fixed a massive problem with some images such as jpeg not decoding correctly. Updated and improved performance on many file types. When using context menu on a thumbnail with checkerboard or canvas color transparency or full thumbnail, options to change them are available. EPub performance improvements. Fixed EPub not loading content files and therefore not working. Improvements to 'Apply to All' state buttons. More visual improvements to context menu icons. Performance gains for context menus.
2023.3.3 12/07/23	AVIF format added to High Efficiency Image format. High Efficiency Image format (HEIC/AVIF) now suports transparent images. Fixed some multi-state buttons icons when in apply to format or apply to all modes. Improved metadata transform button behaviour. Increased performance in double clicking multi-option buttons. Added color conversion support to many image types based on EXIF / embedded color data. About information window updated with some new and improved splendor.
2023.3.2 10/06/23	Fixed a problem where other apps installed may have injected hooks into dialog boxes that was causing the control panel to crash.
2023.3.1 08/06/23	Control panel starting up with incorrect text on the buttons. Better icon representation for choose icon button in apply to all / apply to format mode. Potential crash bugs from other apps not playing nice with the Win32 API and dialogs (Listary).
2023.3.0 04/06/23	!!! This is a very major update - Please read the changes !!! Windows 10 or 11 are now required to install or update from older versions. Windows 7 and 8 support has been retired. Click here to show the last version compatible with Windows 7 and 8. Icon and small icon handling has been completely overhauled. You may notice some differences in the control panel from previous versions with how icons are displayed for file extensions and applications as well as in File Explorer. Czech and Slovak languages added (draft). Checkerboard colors are now per-file extension. Added a checkerboard color chooser with a customizable preset library. To choose the checkerboard colors for a file extension, set the transparency mode to checkerboard and double click the button. Use tooltips (if enabled) in the checkerboard dialog for information. Checkerboard and Canvas colors are now selectable from the shell and QuickView context menus. Added a new option to only show Explorer context menus if holding [Shift] key when right clicking. To enable/disable, double click the global Context Menu button. Small icons for file types that use Windows Store / UWP applications are now shown. Having a file extension small icon generation disabled but assigning it a custom icon now uses the custom icon for small icon, details and icon views. Added older style Office document support for files saved with a thumbnail. (.doc, .xls, .ppt, .vsd). Added Icon (.ico) format for icons. Added .pub Publisher file support. Added .aftemplate extension to Affinity file type. Allow manipulation of full thumbnail mode when in apply to all formats on a base format that doesn't support it. Opening multiple QuickView files from Explorer when the QuickView app was not already open would not open them all. Popup sliders for max file/pixel size and gamma are now presented correctly in dark mode. Clear thumbnail cache after entering a license key was not functional. Crash fixed in updater introduced in beta preventing updating from within the control panel. Updates from current beta versions will have to be made directly from the website. Control panel help button was not available if there was no internet access. It now resets to local help if no interenet access. Embedded thumbnail mode could have caused a lockup for some file types. Pressing ESC key during tutorial could crash the control panel. No double click support on transparency button when file format doesn't support transparency. Canvas color shows correctly now in scale up/full size button. When changing between different file extensions of a file type, the associated application / icon was not being updated with different associations. Choose icon dialog now works with redirected Windows 10/11 icon libraries that are in System32. When changing a file extension overlay icon, the search for extension icons were not being updated correctly. Issues with installer/uninstaller and languages. Fixed bug with choose icon dialog OK on no file chosen. Fixed potential bug with WMF/EMF files. Fixed crash copying QuickView window to the clipboard. Potential bug with the control panel language combo box not exiting active mode properly. Changing from small icons to not-small icons didn't show the default icon proper. This should now be fixed. Attempt to fix QuickView sometimes opens with a blank canvas. Archive (.zip & .rar) files no longer respect/apply transparency, scale up or full size options. Improved gamma slider tooltip in QuickView. Disable transparency button when not in apply to all mode and the file format doesn't support transparency. Double clicking scale up/full thumbnail when the file format doesn't support full thumbnail will instead just toggle scale up. Various cleanups to prepare for release. Optimized HDR, PSP, PVR, SKP file format decoding. Improved HDR decoding performance. Faster and more visually pleasing control panel refreshes when changing modes such as dark mode, expert mode and changing file types. Removed contol panel sound functionality. It was unnecessary (originally designed for accessibility) and only partially implemented and overly complicated. Improved selection visibility in the choose icon dialog. For canvas color transparency mode, select canvas transparency mode then double click the button. Improved clear icon cache so it doesn't restart Explorer if the icon is deleted successfully. Added a notification so changing a file association automatically refreshes the control panel. Adjusted/optimized some file format registry settings. Improved the choose icon dialog to keep selected icon when switching icon size. Improved refreshing folders when changing thumbnail/icon enabled. Many optimizations on registering and unregistering MysticThumbs for system stability. Optimized DSO file reader (3ds Max, Kubotek, Office Document, Publisher). More changes to small icons to use the icon of the application that opens them, or the default assigned icon of the file type, when small icon thumbnail isn't enabled. A new check added for potentially invalid registry links with file associations when unregistering a file extension. Made extraction of icons when small icons is enabled possible to be done using a background thread. May improve performance. Added tooltip text for control panel main window combo boxes to show that keyboard searching is possible. Improved performance of system file types (JPEG, PNG, TIFF, GIF, CUR, ICO and other WIC defaults files.) Changed sampling button text. Postscript performance: changed pinging for properties to use embedded thumbnails when found to prevent very large files stalling Explorer. Large postscript, including Adobe Illustrator .ai files were taking too long to inspect. File types that don't support full thumbnail backgrounds no longer support toggling their full thumbnail setting in the control panel. Optimizing and attempt to fix PNG images that are determined to be Metro/UWP icons. A lot of internal refactoring. Changed registering support file types properties from Picture;Image to Picture. Cursor and Icon formats now default to nearest sampling filter. Some changes to small icon extraction.
2023.2.0 08/01/23	This is the last version supported on Windows 7 and 8. Added Affinity file type. Only supports .afphoto, .afdesign and .afpub files saved with embedded thumbnails. Fixed a bug when extracting thumbs from SmartCAMcmc and Pulse Signature Embroidery files. Refresh open Explorer windows after changing custom icon overlays in the control panel. Added .mun extension to Choose Icon dialog for Windows 11 type icon libraries.
2023.1.0 05/01/23	This version should fix a bunch of things with small icons and thumbnails when enabled/disabled that were a problem in prior versions. Bug in compressed Corel CDR files. Attempts to drill too deep into archive files causing recursion and slowdown. There were some problems with EXR using multithreaded mode. Improved refresh of desktop and Explorer windows when clearing thumbnail cache. OpenEXR, when used, shutdown improved to reduce memory leaks and potential crashes.
2022.3.2 31/12/22	Warning, small icons are always enabled in this version regardless of the control panel setting. Archive (ZIP/RAR) files were causing Explorer to lock up generating thumbnails with some types of content. Possible race condition / lockup when reading some postscript or ZIP/RAR files with postscript files within. Changed the default of 'Apply refreshes open Explorer folders" to Enabled. Holding [Ctrl] key when opening the control panel will reset some key settings back to default in case there is a problem. Some code cleanups. Some internal potential bug fixes when looking for file types that don't exist.
2022.3.1 22/12/22	Warning, small icons are always enabled in this version regardless of the control panel setting. If you had problems with version 2022.3.0 and are running an older Windows 8 or 7 OS you will need this version to fix. There are some other incoming important changes coming in the next few days. Stay tuned. Regression from version 202230: introduced a dependency on Windows 8.1 that caused the control panel to not open on prior versions of Windows (8, 7). Now able to enter a user license over a machine license if desired. Useful for situations such as the user license having a newer maintenance date than a business license so more recent versions can be installed and used. Enter license key dialog improved for better clarity when entering a license key. Potential crash when entering license key. Right clicking the tray icon to get a context menu may have (almost certainly did) shown the context menu twice. PES Embroidery files did not work. Now they do. Optimizing and attempt to fix PNG images that are determined to be Metro/UWP icons. Allow cancellation of toggling debug logs using ESC key. Increased size of restore button state to default in control panel for greater clarity.
2022.3.0 26/11/22	Warning: This version is not compatible on Windows 7 or 8 (8.1 is fine). It will be removed in time. Major update overview Administrator users can now install an 'all user' license seat on a machine so that users can switch on that machine on just one seat. Regular users on a machine with an 'all user' license installed will now have their own profile setup automatically when required. User created format plugins can now be loaded from the as-before install directory or from their user app data folder for development purposes. Much improved File Explorer folder refresh for both thumbnail and small icon modes when using Apply Refresh or Refresh Open Folders options. Many other fixes and optimizations. Detect new non-admin user accounts and setup everything when required. Plugins now loaded from both user %LOCALAPPDATA% and the install folder so both admin and user plugins are read. User generated plugins with the same name are prioritized for ease of development in multi-user environments. See the Plugin information in the user guide online for further information. Buffer overrun on some dynamic icon generations. Some buffer overrun potential bugs. Some more logo animation types in control panel for some visual variation. Installer required GhostScript version set absolute to 9.56.1. Do not try to update Ghostscript to a newer version for now as there are some incompatibilities. Some language string changes and translations. Updating Explorer folders when many changes are made so thumbnails are updated correctly. Cancelling a search in a combo box (eg. search / file format / extension) will properly restore the previous selection. Control panel: File extension search button is now disabled whilst file extensions are collated to avoid possible UX bugs. Potential control panel crash when previous plugins dont exist. Some multi-threading improvements to decoders. Refreshing icon cache on Apply to open Explorer windows when any window is in a small icon mode so the icons will immediately reflect the appropriate changes. Some DDS file formats didn't report their bit depth correctly. When applying changes to formats with small icons enabled a folder refresh is issued to update small icons. Toggle all blocked folders will now update all of those folders immediately. Toggling a blocked folder will (should) now update the small icons and thumbnails appropriately. Applying changes from QuickView when "Apply changes to file" is enabled improved and fixed for gamma correction. QuickView issue not displaying context menu sometimes. Improved the way small icons are handled when enabling/disabling and also with blocked folders. General code cleanups to improve efficiency. PSD decoder improved.
2022.2.3 11/10/22	Context menu validation check to prevent possible crash. Fixed up some non-translated language items. Removed "for current apply to state" redundant text from tooltip for restore default state. Regression - file properties / details mode information may not have been reporting and missing in some situations such as when both thumbnail and small icon modes were disabled for an extension. Changing thumbnail adornment in the control panel now updates the shell windows appropriately. Updated thumbnail adornment button images for better clarity. Updated theme button image.
2022.2.2 27/09/22	Convert to... context menu was broken. Should be now able to convert most file types to the usual targets.
2022.2.1 26/09/22	Improved fetching of file extension and associated application icons in control panel. They should now be more accurate representing default Windows 10/11 UWP and default Windows applications. Updated user guide with double click gear icon control panel images and information.
2022.2.0 21/09/22	New Blocked Folders and gear indicators on control panel buttons for extra features for clarity. Blocked folders (experimental privacy feature) - double click the control panel folder recurse global button to select folders that will be ignored for thumbnailing. Control panel controls that support double click to open extra functions or toggle second functions now show a gear icon overlay as an indicator. Choose custom icon button correctly reflects multiple states in file format / all file formats mode. User plugins may not have been working binding. Should now be working. You can now change the show icon overlay setting for file types/extensions even if thumbnailing is disabled for that type. Across installs, now remembers state of Win11+ 'Legacy Explorer' context menu setting on the notification tray icon across installs/uninstalls/updates. Default all context menu wasn't restoring metadata rotation. Removed change gamma control from the shell context menu except for default. Gamma control only available from QuickView or the control panel. Reworked file format and extension icon associations. UWP, Windows Store and default Windows 10+ applications should now be better represented. Sort extensions by extension number where appropriate. Added .blend1 through .blend32 file extensions to Blender file type for users that use the backup system to the maximum of 32 backups. Removed transparency support from blender files since they are thumbnail only. For file types that only support embedded thumbnails, the Transparency option is now locked to Canvas mode because the canvas color can be used for full thumbnails and wants to be visible. Some control tooltip tweaks.
2022.1.3 25/08/22	Control panel was possibly getting keyboard events that it didn't want when not the foreground application.
2022.1.2 22/08/22	Using local help mode (F1 in control panel) the help was not being displayed.
2022.1.1 22/08/22	MysticThumbs build numbers are now Year.Version.Revision numbering format. This significant update contains extensive rework of some major systems for performance and optimization as well as some changes to the control panel settings. It should notify you when opening the control panel and show you the changes. Please consider taking note of the changes. While a lot of testing has been done, due to the myriad of different machine setups, there may be unforeseen issues for some users. If you experience problems please use the support request from the control panel or website to notify us and revert to the previous version. Worth noting: Refreshing or changing settings in Explorer through context menus is now massivey faster and very useful due to multi-core capabilities. Try it? Control panel Scale Up and Full Thumbnail modes have been merged into a single button. Single click to toggle scale up mode, Double click to toggle full thumbnail mode. Tooltips and tutorial have been updated to reflect this change. Explorer and QuickView context menu now have 'Metadata rotation' entries. Full thumbnail canvas color mode added. Fixed. Added Commodore 64 (C64) file type including file extensions .kla, .koa, .prg, .fli, .shi, .esh currently, for Koala painter multicolor images and fli and shi images that are not encoded in d64 program format. Control panel at unusual screen scales could cause a crash. Small icons would render with full thumbnail if it was set, which was not correct. They are always now transparent and achored for better clarity. When opening QuickView, sometimes the window would require a manual refresh/resize. Crash when unregistering/reregistering plugins. Support for checkbox controls - proxy dialog. WEBP animated image support added. The first frame is used. WEBP now requires having a WIC codec installed on your computer. Windows 11 and 10 should already have one installed by default, older OS may require installing one either from Microsoft or another vendor. Switching Global overlay icon will properly refresh open File Explorer windows. Global checkerboard option icon will show light or dark checkerboard depending on currently selected file format. When changing multiple files at once using the context menu a refresh was sent to the window which would reset it's position. This has been removed as Explorer seems to now be better at refreshing the thumbnails according to size correctly in recent Windows builds. If thumbnails don't show at correct size after a context menu file refresh then press F5 to manually refresh an Explorer window. QuickView now supports viewing supported file formats that have been disabled in the control panel. Theme dialog load theme icon improved. Removed tutorial videos as they are legacy. After entering a valid license key the thank you dialog defaults to clearing the thumbnail cache to refresh evaluation thumbnails. When clearing the thumbnail cache you can choose to also delete all thumbnail overrides you may have made on individual files in Explorer. Using tray context menu / clear thumbnail cache now opens the control panel / clear thumbnail dialog so you can choose what to clear. Now unable to open registration dialog more than once if using the Register tray context menu item. Tray icon is more visible now when thumbnails are being generated. Potential crash when un/re-registering/applying changes to file formats. Changed context menu Convert to file format to explicitly say "Convert to ..." for clarity. Improved Restore All context menu so it doesn't process files more than once. Stabilized and improved performance with open explorer windows refreshing from control panel or context menu. Context menu text Embedded thumb changed to Embedded thumbnail for consistency. Changed tooltip for thumbs generated link to "Reset count to 0" for clarity. Changed 'Control Panel' menu item text to 'Thumbnail Control' for clarity. Added a new tray icon context menu entry for Windows 11 to be able to toggle old style / pre Windows 11 shell context menus so it doesn't take two clicks to get to standard application menus. QuickView clears border color in border opaque areas with white or black depending on system Dark Mode setting. Rotating embedded thumbnails of RAW file thumbnails correctly. Added context menu "Default All" to restore any changed file/settings back to current defaults for the file format/extension. Added context menu "Default All" to restore any changed file/settings back to current defaults for the file format/extension instead of one at a time. Added an 'Apply Changes to Open Explorer Windows' global option. If you want to compare changes live, enable this option to make changes and apply to refresh open Explorer windows to see the changes immediately so you can do comparisons etc. live in Explorer. This option was already available via pressing [Ctrl]+Apply. This option simplifies the workflow. The 'Apply' button changes to reflect this state. Rotating embedded thumbnails of RAW file thumbnails correctly. QuickView clears border color in border opaque areas with white or black depending on system Dark Mode setting. Applying changes to open Explorer Windows now works with Explorer Search windows. Context menu in Explorer windows is vastly improved for visual and performance reasons. A multi-threaded job system is now used to vastly improve performance. Popup sliders in QuickView may not have visually updated. This has been fixed. Potential deadlocks when waiting for tasks to finish on closing shutting down some systems. Changed RAW to use embedded thumbnails for better performance by default. Refreshing / manually changing shortcut links now refresh their thumbnails when refreshed from the source file. QuickView "Always Scale To Fit" color picking was incorrect. Potential issue making the notification icon register and function correctly. Preventing unnecessary flickering and refreshing of desktop & explorer windows when applying non-icon related state changes. Restoring full thumbnail mode may have failed to work. Performance maximum sizes and gamma button sliders now show 'Inactive' when inactive for clarity. Control panel - Sample button showing resizing text was doubled up. Control panel - tutorial potential crash due to missing video player in tutorial mode. Control panel - Global option context menu now displays a more intuitive text when disabled. Fixed updating folders thumbnails and windows when changes are made via context menu. Crash when trying to decode bad WMF files. Removed all Facebook and Twitter links. Added Windows 11 OS detection for some platform spectific functions. Control panel - Rearranged some buttons and tabbing ordering to be more logical. Performance improvement - When applying changes to open Explorer windows (ie. [Ctrl]+Apply) only file extensions for settings that changed in the control panel will refresh. An example - So a window with 100 files and only one PSD file will only refresh the PSD file if only PSD settings were changed. Alignment of checkerboards with Full Size Thumbnails RAW files with dodgy rotation may have returned a corrupt image. Control Panel - Apply all changes to open windows is no longer available if there are no changes to any file. Photo orientation meta tag support for RAW images. Some memory leaks and various bugs.
5.2.5 22/08/21	Newer versions of Ghostscript should now work after v9.52. When creating a support ticket the auto control panel screenshot is taken in English to help the support team.
5.2.4 28/06/21	Re-implemented multi-monitor and HiDpi monitor support. Intentional regression from v5.2.1. Windows 10 seems to handle things without crashing now - if you have any problems please report a bug. Opening previous windows such as the Control Panel and QuickView should now better handle multi-monitor systems. Some rare control panel closing issues that may have caused a crash.
5.2.3 09/04/21	Ghostscript required version was incorrect. Reset to 9.52. If you happen to have a newer version(s) please use Windows Add/Remove Programs first to remove newer Ghostscript versions as they can cause issues.
5.2.2 07/04/21	CR3 file extension added to RAW file format. This may require installing a WIC codec pack such as Microsoft's Raw Image Extension from the Windows Store. Quickview may not function correctly with these files (being investigated). RAW and some other WIC based files forced embedded thumbnails may not have been rotated correctly. This may cause rotation issues with some pre-existing files (please report if so) due to some cameras not rotating thumbnails in accordance to image rotation metadata. Potential files not thumbnailed if they had bad extension case.
5.2.1 23/03/21	Added nfo, md, diz and json to Text file format. Ghostscript dependency locked into 9.52. If you happen to have a newer version please uninstall it first or you may have problems with postscript based files. Fixed network error messages when refreshing license keys. Removed DPI aware capability as it was causing issues on some multi-monitor systems. Made text file format thumbnail scale roughly 80 columns wide. Changes to Hardware ID calculation to prevent changes with Windows reinstall.
5.1.9 01/10/20	Please note v5.2.0 has been removed because of issues with Ghostscript causing some postscript files not to be converted. We are looking into this. If you have problems with postscript files not converting please revert to this version. Removed Microsoft Codec Pack for RAW prerequisite installer as Microsoft has terminated support along with Windows 7 and it is no longer available from their servers. No change to existing installs are made and your RAW files will continue to be thumbnailed if you already have it. New users may have to source it from elsewhere if required. There is still a fallback for older and more generic RAW formats that should work for most cameras without the codec pack. Internal structural changes and bug fixes. Recompiled with compiler fixes and optimizations.
5.1.8 15/08/20	Shell Convert to file format was not working for non-ICO files. Regression from v5.1.5. Control Panel Control panel crashed when clicking on and off some links and buttons, i.e. version info link and performance sliders. Improved default icon for control panel sounds so it is clearer in both light and dark modes.
5.1.7 31/07/20	Shell Fixing incorrect registry default file type links upon uninstall. Possible regression. Note that this fix will not take effect until uninstalling or updating this version. Added .jpe and .jfif extensions to JPEG file type. Control Panel Optimized restore default state text. When changing global option to show/hide icon overlays, some times the Explorer would not sync correctly. Dark mode support for the update buttons in update available dialog. Potential crash with tooltips in update available dialog. Update progress dialog progress bar was in a bad position.
5.1.6 03/07/20	Installer asking for Ghostscript update when it should not have. Shell EPUB now supports newer v3.2 packages. Control Panel Made choose canvas color dialog dark mode compliant and further customized.
5.1.5 18/06/20	Updating from earlier versions will update Ghostscript to version 9.52 if required. Shell Open Office files now default to a white canvas background due to issues on Windows Dark Mode. EPUB files - some files did not show a thumbnail. Improved performance of context menu convert file to format. Control Panel Performance improvements to the control panel.
5.1.4 24/05/20	Control Panel If updating and there is no update button in the dialog, press bottom right of the dialog where OK usually is to perform the update. Control panel non-modal dialog boxes are correctly set to pinned/unpinned if the option is toggled. Export debug file extension info had a problem exporting extensions without associated file types. Some button image changes to better suit both dark/light modes.
5.1.3 15/05/20	If updating and there is no update button in the dialog, press bottom right of the dialog where OK usually is to perform the update. Fixed support for older format .ai files with embedded thumbnails.
5.1.2 08/05/20	If updating and there is no update button in the dialog, press bottom right of the dialog where OK usually is to perform the update. Dark mode initial implementation - experimental and not officially supported. See new dark mode toggle switch in the control panel for more information. Updated DirectX (.dds) to support more formats and files with DX10 headers. Some language translations new line breaks were not correctly marked up. Control Panel Cancelling save as dialog in theme editor showed a spurious error. Fixed control button text overlays for changed values such as gamma to work on dark and light themes.
5.1.1 12/04/20	Italian translations updated. Converting a file using the context menu would crash if file already existed (regression.) QuickView Improved performance of context menus. Convert file context menu could save to the wrong location in QuickView. Fixed and improved context menu convert to file type 'Replace All' dialog when converting more than one file.
5.1.0 02/04/20	QuickView Context menus in Explorer and QuickView now all have generic 'Default' options for option resetting. Moved gamma correction context menu out of a submenu for clarity and easier access since there is only one item to choose from.. QuickView for Postscript based files now adjusts for screen DPI. Control Panel Changing language in the control panel now immediately updates any open QuickView windows and the tray application menus.
5.0.9 26/03/20	QuickView Added an "Always scale to fit" context menu option to QuickView that overrides the file / control panel settings so scaling the window will always scale the image if desired. Large images opened in QuickView would open the window too large for the monitor and lose the title bar off screen. An auto QuickView (from pressing Space bar) window will no longer update the current file when multi-selecting files in a shell folder. Improved responsiveness when selecting different shell folder items with an auto QuickView open from pressing Space bar. Disable QuickView Scale menu items when 'Always scale to fit' is enabled for clarity. Improvements to QuickView placing windows on screen. PDF images for HiDPI monitors for a more consistent QuickView size across monitors. Improved resizing Quickview window from placing the title bar off screen for images larger than the monitor. Control Panel Searching through the file formats list using the keyboard was not working correctly. Executables with corrupt or missing icon resources could cause a control panel crash. Control panel would sometimes crash when closing. Some potential control panel crashes on exit. Some machines with error prone file extension information in the registry could cause the control panel to crash when opening. Potential bug initializing graphics device causing control panel crash or failed thumbnails. Improved some control panel information dialogs. Added Cancel buton to clear thumbnail cache dialog for clarity. The dialog close button or Escape key still also cancel. Crash dumps of control panel and quickview tasks are now available in %LOCALAPPDATA%\MysticThumbs\CrashDumps to help debugging for the developer. Shell CBR and RAR files now should show the appropriate dimensions of contained files / selected page. Potential error showing correct context menus in Explorer / QuickView for some menu items. Explorer context menu had redundant separators for disabled file types/extensions.
5.0.8 01/03/20	Clicking on control panel version link button did not correctly go to the relevant version history link web page. Updated to Ghostscript 9.50 with security adjustments. This version should now be asked to install on update. Ghostscript prerequisite install is now quiet and doesn't require user interation once accepted. Uninstalling Ghostscript option on application uninstall for a more clean uninstall process. MysticThumbs installer now requires initial Administrator priviliges to start the installation process. This is a combined effort to reduce the amount of admin elevation requests when Ghostscript etc. are required for install and uninstall. Unfortunately this means the user if locked into user mode is not able to see the initial information before install. This is regrettable. Improved / fixed the size and image of the uninstall icon the Windows Start Menu.
5.0.7 17/02/20	Please note that this version has some issues with Ghostscript causing File Explorer to stall when decoding thumbnails. If possible update to the next version or downgrade to the previous version if you experience this issue. Added Blender (.blend) preliminary file support. Embedded thumbnails only. Added 3D Print file format (.3MF). Files must have an embedded thumbnail. Some files with thumbnails stored in ZIP format may have not retrieved the thumbnail due to filename case sensitivity. WMF metafiles didn't correctly support transparency. Files without an associated application would show as 'MysticThumbs file' which could be confusing. Now they correctly show i.e. 'PSD file' for .psd extension. QuickView could fail to open files after switching between Explorer windows. Control panel file types now default to the most common extension for clarity. Control panel sounds now default to mute. Improved thumbnail generation time for all files. Should improve thumbnail generation time for folders with many files. Improved PSD thumbnail performance.
5.0.6 29/01/20	Missing translations. Some buttons not showing correct info tooltip. Some bug fixes.
5.0.5 09/09/19	Pressing space bar in a File Explorer search window could spawn QuickView if enabled.
5.0.4 12/08/19	Refreshing or entering a product / license key renewal may have still been stuck in version trial mode.
5.0.3 06/08/19	Some PSD files with RLE compression may have caused misalignment, crash and invalid thumbnails during unpacking.
5.0.2 04/07/19	Context menus now when opened highlight the active state(s) to help identify the currently active states for the file selection.
5.0.1 01/07/19	Language mapping in some languages had issues causing things like dialogs not opening at all in the control panel.
5.0.0 20/06/19	Theme Editor. Edit and share your MysticThumbs icon themes. Sharing via the website coming soon. For now, send your themes to our website support to share them. Added High Efficiency Image Format (.heif, .heic) file format. Added .reg extension (Registry file) to Text file format. File Explorer context menu now has override options for full size thumbnails. Some ZIP files would lock up generating thumbnails due to some internal inconsistensies such as MacOS metadata.. Potential issues switching through files in QuickView using cursor keys. SVG with DPI related units such as inches are now sized appropriately especially on HiDPI displays. Potential crash / error thumbnailing multiple web rendered thumbnails concurrently. SVG rendering was bugged in some situations such as HiDPI displays. This has been re-written to account for these issues. Japanese translations updated. Sometimes if the tray app was not already open, a QuickView operation would fail the first time. Potential crash/leak with rendering SVG files. Fixed potential control panel group text overflow formatting issues for some languages. Some translation adjustments. Removed exception reporting as it was causing some issues. If exceptions occur now it will be necessary to manually report them if required using support. Attempts to fix issues with some compound button images that had irregular bitmap formats. Potential crash or graphical issues with systems with weak, dual or non-existant graphics cards or bad drivers. Disabling global thumbnail mode could lead to a lockup in the control panel. QuickView shows transparent images on dark background theme when appropriate. Telling File Explorer that thumbnails are alpha always even if failure may return thumbnails in their correct transparent form. Added extra error checking logging to help trace user issues. Possible control panel crash when opening with dodgy graphics drivers fixed. There was no state information on the full thumbnail appearance option in novice mode. Regression from v4.9.8. Was unable to middle click to select a new tutorial button. Global thumbnail enable option not darkening background like other dialogs do. Some issues with a few version updated tutorials. Some operations could have caused a deadlock in the button renderer, i.e. toggling the tray notification icon. Should be fixed now with a multithreaded renderer. Full transparent thumbnail options in the context menu are now in parity. Potential menu item text corruption with some items. Top shelf icons are ghosted to reduce clutter. Hovering the mouse or keyboard focus brings them to full opacity. They have also been moved around a bit to save space. Tray application icon sometimes showing when it should not. Improved some issues if other apps/windows are bought to focus whilst operating the control panel. Improved performance of control panel when darkened with slider or dialog boxes open. Improved rendering of sliders to remove glitches. Updated info and tutorial buttons. Moved some top shelf buttons around for space saving. If skipping by cancelling the warning dialog for disabling global thumbnails and deselecting the ask again checkbox, the button would not have toggled again unless [Shift] was pressed. Canvas transparency context menu option shows correct canvas color where possible. Changed some icons so they are more visible on both light and dark theme. QuickView menu items for changing checkerboard size now only appear if the file is in checkerboard transparency mode. Tooltips for full size thumbnail control panel option now gives a description. Improved button representation of switching between debug logging modes. When choosing an overlay icon in file format mode, the new button icon might not have refreshed correctly to the new icon. Improved size of images in low DPI control panel buttons. Sound (.wav) files in transparency mode on Windows dark theme now show a light waveform when refreshed. Improved QuickView icon for Explorer dark theme. MysticThumbs used to attempt to correct embedded thumbnail rotation and cropping but it would often be incorrect due to inconsistencies in cameras etc. This is no longer done so thunbnails may appear rotated incorrectly and with black borders. Improved debug export of extension keys from control panel. Sound (.wav) did not show the waveform correctly when set to Opaque transparency. QuickView window placement. Opening QuickView with multiple selected files would sometimes drop one or more of the files from being opened. Selecting control panel screenshot when making support request did not work. Also, ability to delete the screenshot would be hampered for a while. Control panel screenshot when making support request compression quality improved.
4.9.8 22/02/19	Some files with embedded thumbnails did not render in some situations. PSD without 'Maximize Compatibility' option in particular affected. Improved selection algorithm to choose embedded thumbnail. Resetting the small icons setting to default did not work as expected. Small icons are not as efficient to generate as regular thumbnails, therefore the default state of small icons has been changed to disabled for better overall program performance.
4.9.7 09/02/19	Some files including JPEG files with camera rotation applied could cause an image processing CPU stall. Regression from v492. About information updated and improved. Improved cycling of control panel checkerboard scale/anchor button.
4.9.6 17/01/19	Paging through Archive files using context menu. RAR files were not working correctly. Possible crash reading archive files. Possible crash cleaning up Internet Explorer rendered files. Improved rendering of postscript based files in preview pane. Improved postscript / exif search for thumbnails and renderability. Changed some context menu and control panel information text for better clarity. Copy to clipboard in QuickView now always uses transparent mode. Prevent multiply copies to the clipboard when [Ctrl]+C is pressed and held in QuickView. Some files, .xml, .txt, html, .eml could get locked and undeletable / unmodifiable. Change ping on Postscript files to report correct size based on embedded thumb if exists, due to artboards possibly different from actual image dimensions.
4.9.5 08/01/19	Small icons were being computed when disabled in some cases. This has been improved. Archive files (ie. ZIP) did not respect the context menu page option. Using context menu 'Thumbnail->Refresh' could sometimes leave behind hidden __mystic__ files that were used to update the parent folder thumbnails. This feature has been changed so that no temporary file is created. If you find any empty hidden __mystic__ files you can safely delete them.
4.9.4 03/01/19	Fixed crashing from Archive/ZIP files from contained files with a percentage sign in their name. Some graphical issues with the warning icon when removing/adding license keys. When entering a license key the accepted dialog was not displayed. Checkerboard scale global option has changed. When on touch devices and in tablet mode, you still double tap the button to change the checkerboard scale. In desktop mode simply click or right click the current anchor point on the button to change the scale. Updated Spanish translations.
4.9.3 13/12/18	Archive thumbnails looked bad. First attempt to make them better. Improved archive (zip / rar) thumbnail rendering and performance. Archive (zip / rar) thumbnails now show HTML based images when supported instead of a generic icon. Refreshing renewed license keys may have not correctly represented correct maintenance date. Some issues with temporary trial build licenses. MHTML (.mht) extension moved to new file format group - Web Aggregate. Settings may have to be reset for these formats. Added .mhtm and .mhtml extensions for this format. Email stationary (.eml) files did not render correctly. Regression from v4.8.0. Improved performance of SVG decoding. ASPX files rendering improved. Changed the way PSD handles multi channel mode files. In some cases the color may not be correct but before the file may have displayed nothing but white. (Photoshop file specification issue). Fixed wait cursor in QuickView when decoding / processing images. Improved performance of large Photoshop files. Premultiplied / non-premultiplied appearance settings were not respected - regression. QuickView icon optimized so it is clearer on Explorer dark theme. Improve performance of the control panel logo.
4.9.2 20/11/18	Fixed lag when holding [Ctrl] key in the control panel continually recreating button images and bogging down the CPU. Postcript file type didn't support transparency or embedded thumbnail options and automatically extracted embedded thumbnails which caused problems with files saved from some applications. Plugins loaded might not have kept correct states. Language control panel was not resized correctly in all language / DPI settings on all Windows versions.
4.9.1 9/11/18	Fixed regression issue with some files getting stuck generating thumbnails on pre-Windows 10.
4.9.0 8/11/18	Do not use this build on Windows prior to Windows 10 as it contains an issue with files getting stuck generating thumbnails. Indeterminate states for slider controls (performance and gamma) did not correctly show multiple states. Multiple states for novice mode icons and text for buttons. Toggling overlay icon is now always available instead of only when override icon is enabled. This disconnects their reliance on each other and allows more intuitive icon overlay control. Gamma control now always shows two decimal places on gamma value. Improved registration dialog button tooltips. The remove license button in the control panel now prompts for confirmation. Enable/disable tooltips now shows a disable icon overlay when disabled. Updated OpenEXR to version 2.3.0. OpenEXR now supports parallel decoding for improved performance. Potential deadlock when performing some tasks such as clearing thumbnail cache, exporting settings. Improved choose and show icon overlay button images based on apply to state. Automatic check for updates would crash if choosing to update from notification balloon. Gamma correction to images within archives sometimes was not applied. Changed gamma button page size to 2.2 for simplicity to push linear color spaces into sRGB. Multiple states for novice mode icons and text for buttons. Indeterminate states for slider controls (performance and gamma) did not correctly show multiple states. Incorrect subtext in novice control panel mode when changing an appearance option. Tray application sometimes not responding to registry changes. When in Apply to All mode changes, the Apply overlay may have been incorrectly shown on some buttons. When opening control panel via "Register" context menu the online store page no longer opens explicitly. Installer now asks for Administrator elevation before installing instead of when running, so information and other details are visible to non-administrator users. Added a warning symbol to Enable all Thumbnails button when disabled to help clarify the global implications of this function. Closing control panel deadlock under some situations such as having done a "Apply and refresh to open Explorer windows". Using context menu in Explorer windows to refresh/change thumbnails could lead to files needing to sync to OneDrive. Improved some epub extraction. Restore original apply to mode after post update tooltip notifications. Potential crashes due to control panel sounds playing. Control panel interface clean ups and performance improvements. Control panel crash when closing after tutorial. Occasional issue / potential error shutting down control panel. Elevate to change site license dialog was broken. Completely overhauled. Improved control panel tooltips on global items to be consistent. Performance improvements to some control panel controls.
4.8.3 25/09/18	Note this version originally had a bug with entering license keys after running with a build trial license. This has been fixed and patched. If you had/have this issue please download again and reinstall, then remove and re-enter your license key. Crash when a process that had used MysticThumbs in Open/Save dialog boxes was terminated. Missing icons in tray menu in some situations. Performance improvement with context menu actions / cache when applying to appearance changes. Performance improvement with button images via caching. Control panel and context menus. Performance improvement in situations where Explorer windows were closed and context menus used again.
4.8.2 24/09/18	Control panel: always show red revert arrow on file extension option buttons when settings are not default indicating that they can be reverted back to default using [Ctrl]+Undo. Before now, this only showed when the [Ctrl] key was held down, now it helps to indicate the item has changed and the option to to revert back to the default state. Defaulted ABR files to light checkerboard transparency in line with other file types. Removed vsync wait on QuickView windows to improve performance slightly. Ghostscript prerequisite installer updated to v9.25. When refreshing thumbnails using Ctrl+Apply in control panel, override appearance settings on open thumbnails are cleared if different to applied settings to correctly apply new settings. Removed unnecessary timer from notification tray application to reduce CPU overhead. Disabled OpenMP code. It's inherently unstable with onoing Visual Studio updates. Some thumbnails may be a little slower because of this but stability should be increased.
4.8.1 14/09/18	Visual quality of cubic sampling not as expected, replaced with anisotropic sampling (regression). Refresh open Explorer thumbnails from control panel not working as expected (regression in 4.8.0). Tooltip icon was distorted on language combo (regression). Using hardware acceleration instead of WARP software acceleration functions to manipulate graphics should improve performance. Improved some tooltip texts in the control panel. Adjusting canvas color for all file formats state machine improved. Cancelling control panel with changes made now allows ESC key to break from the question dialog.
4.8.0 11/09/18	Update notification for Canvas transparency mode with optional restore settings notification. Added Canvas transparency mode that uses the chosen canvas color (double click on transparent button) in the control panel as the canvas behind transparent areas. Opaque transparency restored to always ignore alpha (regression fix from earlier versions). Added control panel "Global enable" mode button for temporary disabling of all thumbnails. Added a thumbnail counter to each file format and extension to track which are most commonly used. This may be used in forthcoming releases for various optimisations and other reasons. Stability fix for random crashes with spawned Explorer processes and other situations. Moving through files with cursor keys in QuickView could sometimes skip some files without a correct refresh. Some files not opening in QuickView. Cubic sampling mode used a high quality cubic filter that would diminish color information when down sampling. Now uses regular cubic filter. When thumbnailing is disabled then the file type / application icon is used. Some thumbnails in transparent mode would show a black background after an Explorer reset. Icons and thumbnails were showing as a blank document when a thumbnail was not able to be extracted. Sound and WMF files rendering to non-premultiplied render targets so they aren't blackened out when final rasterization is done. Opaque mode was not functioning as intended and alpha was will transparent. Alpha/transparency channel is now discarded. PSD files did not thumbnail beyond 15k pixels or large file sizes in some cases. Overlapping log messages from different threads could cause log file corruption. Clear thumbnail cache improvement for Windows 7/Vista MysticThumbs icon not shown in Disk Cleanup app etc. Performance: Restoring file override properties such as transparency on entire folder(s) now only operates on files with an override instead of refreshing all files within the folder. Photoshop support for images with arbitary alpha channels. Crash when closing control panel after using it to refresh open Explorer windows when the notification/tray app wasn't open. Refreshing a thumbnail selection in Explorer was refreshing the entire folder's contents instead of the selection. Checkerboard size/repeat correct for High DPI displays. Fixed / added some help mappings, e.g. Proxy dialog. Improved a lot of task / question / information / error dialog boxes. Some buttons didn't make sounds. Control panel about/info not responding correctly to keyboard / ESC message. Tutorial mode focus rectangle would be on the wrong control when moving to another tutorial. Clearing icon cache on Windows 10 could throw up a spurious system dialog box saying file not found. Renew now in update window did not open the renew web form. Removed "Delete Thumbs.db files on network drives" global option as it was only minor-functional and unreliable due to the way Windows thumbnail refresh works. Checking download versions had unreliable results in some circumstances, notably beta checks. Fixed icons when removing the app with message box asking if to clear thumbnail/icon cache. On DX11 capable machines, QuickView was not properly adjusting images correctly when scaled. Was able to scale Office files out of aspect in QuickView. Office files didn't report thumbnail size properties. Color values were being reported in QuickView unscaled mode outside of the image. Fixed some issues with some file type icons not showing correctly when they were not 32 bit. Temporary files that were created in the %TEMP% folder for some file formats (HTML, SVG, TXT, XML, etc) that could cause slow down and thrash storage drives are no longer created. Novice control panel mode group highlighting more inline with system colors. SVG now correctly respects transparent areas in the image for transparency modes. QuickView tooltip not showing correct value in expanded window mode. Improved control panel button sizes and placements. Choose Icon control panel dialog box is now resizable.>

4.7.2 15/06/18	The last release introduced some unexpected control panel bugs. We believe these are now fixed and v4.7.1 has been removed and it's changelist is in this version. Logging is disabled from this release until further notice. This is a very large change from the previous release. If you find things are not performing as expected - try the 'clear thumbnail cache' control panel option. Control panel startup crash, esp. on Windows 7 and Vista. Crash due to logging enabled. Temporarily disabled. Visual artifacts in control panel on some systems. Tray icon not visible regression. Icon overlays for assigned applications sometimes not showing for some files.

If clicked in tablet mode or with the keyboard the anchor toggles as before. Massive performance improvement for Photoshop files. Improved performance reading some file formats, in particular Photoshop files. Icons for applications and file extensions are loaded on a background thread so using the Search Loupe and other icon based control panel functions are more responsive. Updated to Ghostscript 9.23 with some performance improvements in PDF, AI and other postscript files. Added some more updated/startup tooltips for changed features such as restore to default settings. Enabling debug logging now also enables installing an exception handler allowing the user to attach a crash dump to an email for investigation by the developer.

Changes to how full size thumbnails and checkerboards are handled for greater parity across file types and thumbnail sizes. Rewrote Web/HTML/SVG etc. parser as it was causing stalls in Explorer windows requiring a refresh / F5 to continue. Re-enabled OpenMP for faster thumbnailing of some file types. Various bug fixes performance optimisations. Uninstall now prompts if you want to clear the thumbnail and or icon caches. QuickView - you can now traverse images from a QuickView that was not opened using Space bar from File Explorer. Changed default thumbnail canvas color for most file types to the system window color (usually white) for a more consistent visual experience when using full size thumbnails for example. Full thumbnail setting for file extensions improved for both thumbnail and small icons. Control panel apply to open explorer windows uses the control panel instead of the background tray task for efficiency. Made global icon override setting show a NO icon when disabled instead of nothing to distinguish the function. QuickView scale to fit not working correctly. Possible crash with threads cleaning up. Potential crash closing control panel depending on how it was spawned. Control panel potential crash when loading internal icons based on process generation state. Occasional crashes generating SVG, HTML, Text, XML etc. IE rendered files. Changing premultiplied (and possibly other appearance states) when in Apply to All mode would sometimes not show the correct new state and appear to get stuck on one state. Added Adobe XD file format added. Added Office Open XML format supoport for .docx, .xlsx, pptx, .vsdx (Word, Excel, PowerPoint, Visio) files. Please note that these files must be saved with embedded thumbnails by enabling the appropriate option in the source application. Window size control panel option. Use to make the control panel smaller or larger depending on your needs. Opaque color for each file extension is now customisable.

Combined global checkerboard scale & anchor into one control panel button. Single clicks change anchor, double clicks change scale. Full thumbnail mode is now a file format/extension option instead of global. PDF now uses opaque rendering along with a white opaque background by default. This fully fixes some issues where settings for PDF were not obvious and producing black thumbnails. Further improvements to control panel or QuickView windows being opened off screen and not visible, they should always be placed on screen or centred if required. Right clicking on the control panel when the about info is running will quit in line with other controls of the control panel. Reset control panel window position on uninstall. Improved QuickView to re-render open windows with changes to the global checkerboard setting in the control panel and when Apply is pressed. Sound WAV files improved rendering for all transparency modes. QuickView sync with settings / defaults improved regardless of the 'Apply changes to file' setting. Reset to defaults undo button now works on the Apply To mode level, so you can reset extensions, file formats or everything back to defaults. Reset control panel window position on uninstall. Improved QuickView to re-render open windows with changes to the global checkerboard setting in the control panel and when Apply is pressed. Sound WAV files improved rendering for all transparency modes. Potential infinite loop when processing archive (zip & rar) and the file is deleted.

QuickView for files without explicit dimensions such as .wav may hae not worked. ZIP / RAR extraction with some files (ie. CDR) is fixed. Extraction of some images within Archive files would not work due to unusual pixel formats. DDS and PVR cubemap QuickView size regression introduced in v4.4.0. When a valid license was installed but the current build was newer than the maintenance expiry date, the registration dialog did not show the hyperlink text explaining the problem. QuickView next/previous file window frame&size adjustments improvoved. Paging with context menu shows which page is next or previous when relevant. Reduced button image rendering overhead.
4.5.7 27/10/17	High CPU / process lockup and errors trying to thumbnail large PDF documents. Due to the Ghostscript delegate renderer, large files may still take time. Consider using embedded thumbnail mode for PDF in this case if possible. PDF now allows for embedded thumbnails.
4.5.6 23/10/17	ZIP files could cause an infinite loop & high CPU usage.
4.5.5 20/10/17	Paint Shop Pro v5 file format was not reading correctly. Improved support for v5, v6+ formats. QuickView copy to clipboard was not working correctly. QuickView was pointlessly refreshing / reloading the image if moved using the title bar. Disabled thumbnails on Html/Text/Xml files within zip/rar archives due to potential endless loop.
4.5.4 17/10/17	Check for updates is now optioned as daily/weekly/monthly/disabled instead of daily. Hover over notification tray icon to show the last 5 thumbnail file names processed. This is a useful debugging tool to track down any problem files in case of an Explorer crash or processing lockup if the CPU hits 100% and stays there.

Added context menu IObjectWithSite interface support for brevity. Size of revert overlay icon on control panel buttons improved so they don't overlap and confuse.
4.5.2 14/09/17	Control panel file type, extension and search combo drop list boxes did not open their drop lists on non-English systems. Regression from v4.4.3. Re-enabled transparency settings for PDF. Some Cursor files eg. .ani were not generating thumbnails. When double clicking the choose icon control panel button and accepting the change, the button now always sets the state of overide icon.

Re-introduced IExtractImage interface for applications that may use it. Updated the user guide local and online help with new and improved function information.
4.5.1 05/09/17	This build is a quick fix to address the unicode filename issues reported by some users. If you have any issues revert to the prior version and contact us using the control panel. Files with unicode filenames sometimes not read/converted with some file types, notably postscript files such as PDF, AI, PS, EPS.
4.5.0 04/09/17	Some file types that require special handling were not working in all situations or users, PDF, PNG, Web, Maya, Postscript, Illustrator. These should now work for everybody. Control Panel shutdown problems. Potential crash on control panel exit is sounds were still playing. Some Metro (Apps for Windows) apps, notably System and App icons would display with checkerboard or opaque when PNG was set to non-transparent mode and enabled. The heuristic that checks for these files has been improved. Postscript files not reporting EXIF information. QuickView was not disableable. Allow Corel Draw embedded thumbnails to be transparent.
4.4.9 22/08/17	Significant changes to the way thumbnails are handled with the checkerboard / anchor / full size global options. If you're playing with these, see what happens. As usual, if things malfunction, revert to a previous good version that works for you and send us a support query. PDF was generating greyscale thumbnails for CMYK documents. They all should now be colour. PDF and some other file types not reporting EXIF / file properties. PDF was not pinging document size. Using [Ctrl]+Apply to refresh open explorer windows and then closing the control panel could cause a crash and not complete the refresh. This task has now been handed to the tray application (QuickView) to perform. Improved checkerboard and full thumbnail button appearances. Apply to all file formats mode in control panel - you can now cycle through all settings such as embedded thumbnails even if the active format does not support them. Changes are still not applied to the formats that don't support the changed setting. Control panel right click followed by left click quickly would go to previous state instead of next state. Checkerboard size on thumbnails for all thumbnail sizes and within folders fixed. Issues with properties not being fetched on some files. Some function descriptions and translations updated. Files that don't support transparency should fill unused space (full thumbnail) with transparency. Checkerboard anchor / full size thumbnails mode completed. When closing the control panel with unsaved changes, the warning dialog now asks to apply and shows an apply icon instead of an ok tick. OpenMP being used was causing intermittant problems with thumbnails getting stuck when generating. Now disabled, some larger thumbnails may be a little slower generating but should be more stable. QuickView did not work for Explorer shell views such as search results. It now does. Jpeg files now support embedded thumbnails. Some system file types with rotations (ie. jpeg) could cause WIC to lock up for some reason. Worked around.
4.4.8 16/08/17	Some new features are still a little experimental and may not be perfect. If anything doesn't work right after updating, uninstall and reinstall a known good version. Multi-state control panel buttons such as checkerboard size & anchor now respond to right mouse clicks or context menu key to go to the previous state. Regression v447, ePub and Archive files may not have extracted embedded images. Regression, active file format was not being restored on control panel open. Some times QuickView would not open. When searching file types using the keyboard, the current selection was not being reflected to the file extension list. More visible arrows on the checkerboard anchor. Some Amiga file type adjustments. When using the search file extensions control panel tool, after a short delay (key repeat delay) the file format for the currently selected extension is activated. Canceling the search restores to the prior format/extension. Improved access to embedded thumbnails for file types that have them, and those that only have them. Files only with embedded thumbnails no longer offer an embedded thumbnail option via control panel or context menus. Changed HTML file type to Web, and added .aspx extension.
4.4.7 08/08/17	Regression, QuickView may not have opened some files. HTML / Text file types had ugly nearest sampling thumbnails regardless of settings. Further improvements to enhance stability on Explorer DLL cleanup. Arrows on checkerboard anchor made red to help with visual impairments. Improved individual thumbnail fetch system overhead & performance. Improved performance of PNG.
4.4.6 04/08/17	Overall stability enhancement as well as regression fixes and a few improvements. Convert context menus had disappeared! They are now back, and ICO now produces always square icons.

Improved graphic of global checkerboard size & anchor buttons. Explorer previews now respect checkerboard size setting. QuickView may not open all files.
4.4.5 31/07/17	Control panel buttons now show if they differ from the default state if you hold the [Ctrl] key and allow you to restore to the default state on a state-by-state basis. Load global default state is still available with [Ctrl]+Undo. AI / some other Postscript files were not recognising the ability to render as a PDF instead of always extracting an embedded thumbnail. ie. Respected embedded thumbnail setting where appropriate. Apply/changed states may have been incorrect depending on the 'Apply To' state. Control panel tooltips now update to show the correct state when modifier keys are changed in real time. Load defaults control panel action now loads the default state without being destructive, so you can undo or apply. Improved combo box drop sound.
4.4.4 29/07/17	Stabilization build to improve Postscript/AI files support and to enhance general stability. As always, if you have problems, use an older version that suits until stability is maintained. PSD dimensions/bit depth not being reported, possibly others. Wait cursor was not showing where appropriate in some cases. Downloading updates would fail after 8 seconds. Unfortunately this fix will only help when downloading the next version and newer. Removed "InProc" style processing of files to reduce cross error rates and to improve performance. Control panel Explorer context menu is now at the root along side Thumbnail and Quickview menus for easier access. Improved performance of small icon and async extraction, should not stall Explorer like it did before. Improved exception handler to not crash when encountering an error when making thumbnails - instead no thumbnail will be made and things should continue. File format appearance buttons disabled when both thumbnail and small icons are disabled. Holding [Ctrl] key to apply changes and refresh open Explorer windows now works regardless of if there are any file format changes so a refresh can be made to update thumbnails for changed checkerboard size/anchor etc.
4.4.3 22/07/17	Stability and bug fix release with a few improvements. This release should fix a lot of problems created from the previous v4.4.x releases. As always, if you have problems, use an older version that suits until stability is maintained. Control panel sounds option, for a touch of distinctiveness. Comes with multiple volume levels and mute. Work in progress. Cubic sampling mode. Only works on Windows 7 with Platform Update or newer with DirectX 11 capable hardware. PDF files were not working due to v4.4 ImageMagick upgrade. Some files were not supporting embedded thumbnails & metadata correctly. Issues with extra large images. Gamma restore icon was incorrect. Postscript / PDF, AI, ABR, PSP files fixed. Register nag balloon was being too naggy. Imprecise initial positioning of QuickView window in some situations. QuickView and possibly thumbnailer were holding a file lock on open files beyond completion of image composition. This could cause app saves & file copy/paste to malfunction. PaintShop Pro files transparent areas didn't respect transprency. Windows 7 & Platform Update, Windows 8 and all newer versions now used even more efficient GPU acceleration for compositing and rendering using DirectX 11. Context menu adjustments from Explorer will now be available if either thumbnail or small icon modes are enabled for a file. Various bug and stability fixes. Sound (.wav) rendering accelerated with GPU. Resizing large PostScript images to a reasonable size when required to make them render at reasonable sizes. PDF scaling in QuickView. Search extensions drop list combo had an erroneous border. It's been removed. Taller control panel file format/extension/search combo boxes. Don't forget these can all be searched by typing for what you want. Optimised realization of QuickView images. Improved icon composition / rendering esp. with multiple overlay complications. File types are now by default non-transparent capable. If any files you expect to be transparent no longer support it please send us a support request. This is a purity enhancement. Improved context menu icons with better clarity for restore/apply icons and a more accurate restore to state icon in most situations. Discarding thumbnail generation when file dimensions/size are set fixed. Improved rendering performance when generating multiple thumbnails concurrently. Improved real time scaling and interpretation for dynamic images (WAV/ABR etc.) Improved QuickView performance when scaling and changing image options, not requiring reload of image. Improved QuickView performance and image quality when running on Windows 7 with Platform Update or later. PaintShop Pro compositing layers improved positioning & scaling. Note that not all composite modes are currently supported so results may vary. This may be improved in the future. Best save with a flattened image/thumbnail for compatibility.
4.4.2 8/07/17	Was crashing on Windows Vista/7 and maybe 8 due to undocumented differences with some API's. Premultiplied crash fix. Postscript files have issues in this version and may not thumbnail. Very large images >8k dimension may not thumbnail.

4.4.0 4/07/17	This is a very large change! If you experience any problems, contact support and revert to a previous version. The control panel has been improved to support changed states. An apply icon () is shown on any changed state before applying to the system. An indeterminate icon () is shown on any button that has multiple states when in file format or all file formats mode. You can now copy & paste icon paths/indexes from the choose icon dialog box so you can apply them to other formats / extensions. Updates now allow installing explicit or older versions. Progressive Graphics File (PGF) file format support added. Resource memory leak with tray / QuickView task. Some icon overlays may have been black when restarting control panel after a reset to default state. Control panel window could be restored to the incorrect position by a small amount on each run under certain circumstances such as having the task bar at the top of the screen. Icon override settings could get into a bad state. Gamma button text value was not drawn disabled when appropriate. Improved icon overlay override behavior and visuals across all file formats. Reworked PSP format to work around some issues with some files. Control panel undo was not resetting the active file format/extension. Potential corrupt palettised icons when not a power of 2 width. Potential crash if renderer accessed by multiple threads. Potential crash extracting file icons.

4.3.4 16/04/17	v4.3.x Windows 7 malfunction due to undocumented differences with Direct2D. Crash decoding some RAW embedded thumbnails. Some rework of process shutdown in the hope it'll prevent lockups and spurious reference counting. Small icon handler may not have been unregistered correctly for file types with more than one extension. Small icons may now be enabled separately from the thumbnail handler. Adornment for file types/extensions is not disabled if the file extension is disabled since it is not dependent on image processing. Supported file extensions are now still enabled in the shell context menu if the global option is enabled, regardless of if the file extension is disabled. If the extension is disabled for thumbnails then only non-thumbnail options are available, such as convert and control panel. Help context links to the correct help topic. Added prerequisite for Microsoft Codec pack to install for Window Vista and 7.
