MysticThumbs full changelog

Improved performance and stability of .zip and related file types that depend on it.
Fixed and improved the way some formats extract their embedded thumbnails that weren't working. Includes 3D Print (.3mf), Adobe XD, Corel, EBook (.epub), Krita, Open Office.
Improved Apple Suite handling to find the best thumbnail.

Corrected JPEG XL to support transparency and use non-premultiplied alpha by default. Users may want to revert the .jxl format to default settings. The Microsoft JPEG XL codec may also need to be installed from the Microsoft Store.

Fix for potential lockups when applying changes from the control panel to postscript files.

Improved SVG, now defaults to non-premultiplied alpha, users may want to revert that setting to default for SVG files to remove transparent auras.
Ghostscript base install updated to 10.08.0. Previous versions should still work.

Bug fixes on previous two builds, primarily to address thumbnails rebuilding needlessly.
Fixed a glitch with thumbnails being reprocessed every time a folder was opened in Explorer or F5 / Refresh was used on a folder.
Improvements to thumbnail recreation issues.
There was an error decoding some Amiga IFF files.
Corrected thumbnails that depend on dark mode settings such as Sound (.wav) to render correctly in dark mode when processed asynchronously in Explorer.
Removed blocked folders function (at least for now) because it was completely unreliable in tandem with process isolation streams. If you want or need that functionality - please use an older version.
Added info for PNG file type about fallback importance.
