Change Log



Changes from v5.1.0:

• New: Edit -> Paste now supports base64-encoded images, which enables copying images from Microsoft Teams (thanks @null54 for the implementation!)
  
• Fixed a rare bug that would cause selection tools to not work until the image was closed and reopened
  
• Fixed: All mouse cursors will now honor the Windows setting for adjusting the mouse pointer size
  
• Fixed a rare crash when rapidly undoing multiple actions
  
• New: Plugins can now access the built-in JPEG and PNG FileTypes through two new methods on IFileTypesService
  
• New: The Paint.NET Plugin API Documentation website is now live at https://paintdotnet.github.io/apidocs/
  
• Fixed: All of the custom Direct2D effects now have runtime metadata (DisplayName, Author, Category, Description), which is useful for a UI that lets the user browse them (e.g., node editor)
  
• New: Added convenience constructors to many Direct2D effects so that they can be used without declaring a new local variable
  
• New: Added GaussianBlurMapEffect and BokehBlurMapEffect for use by GpuEffect plugins. They enable the blur radius to be controlled per pixel through the use of a second input image (the “map”)
  
• New: Added a RandomNoiseEffect that GpuEffect plugins can make use of
  
• Fixed various bugs with HlslBinaryFunctionEffect, HlslBinaryOperatorEffect, and HlslTernaryFunctionEffect (which can be used by GpuEffect plugins)
  
• Added Distance and Dot to the list of HlslBinaryFunctions
  
• Added Length and Mad (multiply-add) to the list of HlslTernaryFunctions
  
• Fixed the Environment property’s runtime type when accessed from an EffectConfigForm (for BitmapEffects and GpuEffects with custom UIs)
  
• Fixed UIScaleFactor’s methods for converting between DIPs and pixels
  
• Fixed ability to work with EffectConfigForms in the Visual Studio WinForms designer
  
• Updated the bundled AvifFileType to version 1.1.26 (thanks @null54!)
  
• Updated the bundled DdsFileTypePlus to version 1.12.6 (thanks @null54!)
  
• Updated the bundled WebPFileType to version 1.3.20. It now uses libwebp v1.3.2 which contains the fix for CVE-2023-4863/CVE-2023-5129 (thanks @null54!)

Changes from v5.0.9:

• Fixed: When using Alt+Tab, the internal state of the Alt key could get ‘stuck’ when the Shapes or Line/Curve tool was active, causing the next shape or line/curve to be drawn from the center
  
• Fixed: Sliders were not responding to the mouse wheel (regression in 5.0.
  
• Fixed the DeviceEffect.Properties.Min/MaxInputCount properties, which were throwing an ArgumentException (for plugin authors)
  
• Fixed a rare crash at app exit due to a race condition in the auto-updater
  
• Fixed a rare crash when the system resumes from sleep mode due to a race condition in DWM reporting whether composition is enabled
  
• Fixed a rare crash when using copy+paste due to .NET Runtime issue #84994 https://github.com/dotnet/runtime/issues/84994
  
• Updated the bundled DDSFileTypePlus plugin to v1.12.2.0, which fixes the inability to save on ARM64 systems (thanks @null54!)
