This build has everything that alpha build 7542 had, as well as some more bug fixes and tweaks.

To get this update, make sure you have “Also check for pre-release (beta) versions” enabled in Settings, and then click on the Check Now button. (Unfortunately alpha/beta releases are not currently available for the Microsoft Store version of the app).

You can also download and install this update directly from the forum.

Changes since 4.2.14 alpha build 7542:

• • Fixed an issue with copying large images to the clipboard: if an image would take up more than 4GB, it could not be copied because the DIB and DIBV5 formats cannot be larger than that. Now, the DIB and DIBV5 formats are not placed on the clipboard if this happens.
  • Fixed an issue with Effect plugin tooltips which was preventing the menu item from being easily clicked (thanks @toe_head2001 for the fix!)
  • Fixed an issue that was preventing Effect configuration dialogs from working correctly in the Visual Studio designer (thanks @toe_head2001 for the fix!) *
  • Greatly improved performance when saving images at 8-bit color depth *
  • Added diagnostics information to most error dialogs. This is to help with troubleshooting.
  • Updated bundled AVIF FileType plugin to v1.0.5.0. This improves the default speed for saving: “Compression Mode” is renamed to “Compression Speed”, and instead of options for Fast, Normal (old default), Slow, there are now options for Fast (new default), Medium Slow. Thanks @null54!

Changes marked with an asterisk * were actually in the alpha, but I neglected/forgot to include them in the change log.

This update includes upgraded AV1 (*.avif) support (both opening and saving, and not just on Win10) thanks to the bundling of @null54‘s AvifFileType plugin. Performance and memory usage are improved, particularly when working with large images. Saving large, indexed (8-bit or less) image has been fixed, as well as the palette generation for 4-bit images (which was broken).

To get this update, make sure you have "Also check for pre-release (beta) versions" enabled in Settings, and then click on the Check Now button. (Unfortunately alpha/beta releases are not currently available for the Microsoft Store version of the app).

Changes since 4.2.13:

• New: AV1 (*.avif) images can now be saved (not just opened), due to bundling of @null54‘s AvifFileType plugin (v1.0.4.0). Installation of Microsoft’s codec from the Microsoft Store is no longer necessary, which means this also works on Windows 7 and 8.1.
• Improved performance in the canvas rendering engine, especially when working with large images, and most notably when scrolling and zooming
• Reduced memory usage when working with images that have regions of solid color
• Fixed an issue where saving an image at 4-bit color depth (usually pixel art) was using an incorrect palette (reduced color count/quality). This was due to a bug in Windows Imaging Component (WIC).
• Fixed an issue where very large images (e.g. 50000 x 50000 px) couldn’t be saved at indexed bit-depths (8-bit or less) due to a bug in Windows Imaging Component (WIC). More information on the forum: https://forums.getpaint.net/topic/116950-error-when-saving-a-big-file/
• Fixed an issue where BMP images couldn’t be loaded if they had the .PNG extension (there’s an Android screenshot utility out there which does this …)
• Fixed a rare crash in the Gradient tool ("The tool must be in the Drawing state …")
• New: Added a list of the DLLs that are loaded into the process on the Settings → Diagnostics page. This is to help troubleshooting scenarios.

This update adds some additional low-bit-depth choices to several file types (PNG, BMP, TIFF), and fixes some bugs.

If you’re using the Windows Store release, you should get the update automatically within the next 24 hours. You can also force an update check by following these instructions.

For the Classic release, you should be offered the update automatically within the next week or so. You can get the update sooner by going to ⚙ Settings → Updates → Check Now. You can also download and install it directly from the website.

Changes since 4.2.12:

• New: Added 2-bit per pixel support when saving as PNG
• New: Added 1-bit per pixel support when saving as PNG, BMP, and TIFF
• Fixed low-bit-depth saving quality (8-bit, etc.), as it would sometimes produce very bad results (e.g. only using 64 colors instead of 256)
• Fixed: Resizing an image at very large sizes (e.g. 32K pixels to 64K pixels) would fail due to an arithmetic overflow
• Fixed: Sometimes recently saved images would not have an updated thumbnail in File Explorer unless/until its window was manually refreshed
• Fixed: Sometimes saving an image to a network share would not work
• Updated bundled DDSFileTypePlus plugin to version 1.10.4.0, which fixes an issue when loading and saving images using the sRGB color space. This issue was reported here: https://forums.getpaint.net/topic/116572-dds-file-format-bc1-bc7-srgb-export-incorrectly . Thanks @null54!

Enjoy!
