  • Improved: Image -> Rotate should now complete almost instantly (thanks @Bruce Bowyer-Smyth!)
  • 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 (thanks @Bruce Bowyer-Smyth!)
  • 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 (thanks @Bruce Bowyer-Smyth!)

Enjoy! 🙂
