Software Update: Paint.NET 4.1.5

Version 4.1.5 of Paint.NET has been released. This drawing and image editing program bridges the gap between the Paint supplied with Windows and expensive but very extensive programs such as Adobe Photoshop and CorelDRAW. Since version 4.0, the program performs a lot better, especially on multicore processors, but has at least Windows 7 as a system requirement. Since version 4.0.18, the program is also available via the Windows Store offered, but a small fee is charged for that version. The release notes for this release can be found below.

Paint.NET 4.1.5 is now available

This update focuses on improving performance — sometimes significantly! — and fixing a handful of really important bugs. Special thanks go out to @Bruce Bowyer-Smyth for his contributions in this release.

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.

• Improved: Image -> Rotate should now complete almost instantly.
• Improved: Optimized a portion of the rendering engine for newer CPU instruction sets (SSE2, SSSE3, AVX2). Depending on zoom level, CPU type, and other factors, rendering throughput has been improved by 10-50%.
• Improved: Some performance optimizations for code that uses the indexers on the Surface class, which should improve effect plugin performance.
• Fixed: Shortcut keys for the Adjustments menu weren’t working until after you opened the menu for the first time.
• Fixed: Canvas checkerboard, used to indicate transparent regions of the image, now scales with DPI.
• Fixed some of the more rare cases of the SEHException/AccessViolationException crash caused by Direct2D.
• Fixed: A bug in IndirectUI was resulting in a crash when using @BoltBait‘s Level Horizon plugin.
• Fixed: Per-user fonts no longer cause a crash for the Store version.
• New: The paintdotnet: protocol now works for the Classic version.
• Fixed: The paintdotnet: protocol should now work properly with paths that have spaces in them.
• Fixed: Hardened security for loading Custom Shape plugins via XAML.
