SageThumbs 2k Files

What's changed

Added

• Windows on Arm is supported, with its own installer. SageThumbs2K-Setup-<ver>-arm64.exe runs natively on ARM64 Windows instead of under emulation, and it is a full build: it bundles the same ImageMagick engine as the x64 installer, so every format works the same on both. The x64 installer is unchanged.
• EPS files now get thumbnails, without rendering PostScript. SageThumbs reads the safe raster preview already embedded by DOS-EPS, EPSI, or Photoshop, while files with no embedded preview still keep their stock icon.
• Paint.NET .pdn files now get thumbnails. Paint.NET saves a small flattened preview inside the file, and SageThumbs reads that, so you see the picture rather than a blank icon, with every layer already composited. It works on files from older Paint.NET versions as well as current ones, and nothing about the drawing itself is opened.

Fixed

• Submenu menu previews now appear reliably. The preview row is added while the right-click menu is built instead of depending on Explorer to send a submenu-open notification that it can omit for extension-created child menus.
• The General settings page no longer crowds the footer. The checkerboard option now lives with the Right-click Menu preview controls it affects, leaving comfortable space above Save and Close while the two list-heavy pages keep their intentional scrolling.
• Screenshot selections are measured against the right screen on mixed-DPI setups. With a scaled display placed to the left of, or above, the main one, the capture overlay sized its selection outline, handles and readout for the wrong monitor.
• Strip metadata now refreshes the file's thumbnail immediately. Explorer is notified after the in-place rewrite instead of continuing to show the cached pre-strip image.
• HEIC/AVIF edge-case transparency is preserved. Compact-layout AVIF mini containers now reach the bundled decoder, and the Full install's isolated thumbnail/preview handlers route affected HEIC files around the Windows decoder that flattens their auxiliary alpha.
