Paint.NET version 4.3 is available for download

Version 4.3 includes the following new features and improvements:

• New: The app has been upgraded to .NET 5, which has greatly improved performance.
• New: ARM64 is now supported on its own, which improves performance on devices such as the Surface Pro X.
• New ones
• New: Portable Zips are now available. Note that portable installations are not currently updated automatically.
• The performance of most effects and other predictive-intensive tasks has increased by an average of about 20% due to the improved code development of .NET5.
• Improved startup performance for Microsoft Store releases. Previously, the .NET Framework’s NGEN Store was not available for applications, but now .NET 5 enables auto-sorting with Redditron + CrossGen.
• Improved performance: Many parts of the application are optimized to use SIMD on x86 / x64:
  • Drawing a picture with a large number of layers is fast
  • Drawing is faster in the alpha mode of the gradient tool
  • Drawing with the recaller tool is fast
  • Drawing with an eraser or clone stamp tool is faster when using a color whose alpha value is less than 255
  • Drawing is faster in the overwritten mix mode
  • Due to the improved composite performance, drawing with the shapes tool is faster
  • Drawing with the brush tool is faster without antialiasing
  • Tile compression is low overhead as it is compatible with SSE2 and AVX2
  • Working with complex choices is fast
  • Many improvements throughout the application and rendering engine
• The performance of loading custom shapes x 16x on the 2nd day is improved and the next application starts.
• The performance of the Magic Wand tool is considerable.
• Significant amount of performance of the paint bucket tool.
• Improved performance of the paint bucket when changing the color or some other toolbar settings without revisiting the stencil buffer to the filled area. The changes should now be immediately apparent.
• The performance of the Polar Inversion has been enhanced by 3x, as an add-on to fix the bug that often causes hangs, and slightly due to the Net5.
• By assigning 1 core to the enhanced performance UI on systems without hyper-threading. Performance on computers is further enhanced by the use of logical cores.
• Advanced Performance When installing or upgrading an app, the “Improve Performance for Your Computer” level is no longer required.
• Improved memory usage when custom formats are installed so they are not stacked with hundreds of thousands of box value types.
• Improved selection antialiasing quality by using a 4 × 4 super sample filter instead of a 3 × 3 super sample filter. The code is optimized to use SSSE3 on X86 / x64.
• Updated: Effect and file type plug-ins can now be organized into folders. The plugin loader searches repeatedly for DLLs up to 1 folder depth.
• Fixed a bug when saving with “Auto Detect” bit-deep, which already loses credibility in some images of 256 colors or less.
• Fixed: There were some issues with zooming in using the keyboard, where the anchor point was not calculated correctly, causing the canvas to move in the wrong direction.
• Fixed the inability to use the middle mouse panel after using the selected tool and pressing Delete before releasing the mouse button.
• Updated: Plugins are now loaded into isolated assembly loadcontacts, which improves stability and latency for various issues with version, export dependencies, plugin errors, and incorrect plug-in installation.
• Fixed a malfunction when trying to draw a fixed size rectangle selection larger than the image.
• Fixed a bug with the tolerance slider where both 58% and 59% would be displayed as 58%, due to a round issue. The correct value was actually used and it is not displayed correctly.
• Added a / disable plug-in command line argument to help resolve various issues with application startup and incorrect plug-in installation.
• New: Additional directories may now refer to plug-in detection, which uses OneDrive to store (e.g.) plug-ins.
  • Note that this does not work on the portable version of the application, but you can install the plug-in next to the application, so it is not required.
• The bundled AvifFileType plugin has been updated to v1.1.15.0, which includes support for multi-layer AVIF files and adds native support for ARM64.
• The bundled DdsFileTypePlus plugin has been updated to v1.10.10.0, which adds native support for ARM64.
• The bundled WebPFileType plugin has been updated to v1.3.7.0, which adds native support for ARM64.
• Changed: FileType.IsReflexive () is now excluded via [Obsolete], And is no longer honored. However, the Storage Configuration dialog no longer attempts to create previews for file extensions, which do not specify any file extensions to load, this method is used
• Known issue: GPU accelerated effects (Gaussian Blur, Motion Blur, Radial Blur) on ARM64 actually use CPU for rendering due to malfunction.
