Software Update: Paint.NET 3.5.5 build 3767

The final release of Paint.Net version 3.5.5 was released on Sunday. As the name suggests, this photo editing program needs the .Net Framework to do its job. Updating is preferably possible from within the program itself, but downloading is also an option option. Although few or no specific functions of version 4.0 of the .Net Framework are used yet, this is a system requirement from this version. For the same reason, at least Windows XP with SP3 or Vista with SP1 is also required. Version 3.5.5 also fixes a problem with writing 8-bit images and slightly improves performance. The full changelog looks like this:

Paint.NET version 3.5.5:

This update fixes a bug when saving 8-bit images, improves layer composition and Gaussian Blur performance, and is now updated to support the new .NET Framework 4.0 in some cases.

  • Fixed the bug where saving as 8-bit PNG/GIF/BMP wasn’t always working, usually with larger images.
  • Improved the performance of the Gaussian Blur effect by 30-40%.
  • Improved the performance of all the layer blending modes by 15-30%.
  • Improved the performance of zooming with the mouse wheel on dual-core Intel Atom systems.
  • Updated to support .NET 4.0 if no other version of .NET is installed.
  • Reduced download size from 4.8MB down to 3.5MB.
  • Fixed a small error in the Chinese translation.

Please note that the system requirements have been updated. For Windows XP, you must now have Service Pack 3 (SP3) installed; SP2 is no longer supported. For Windows Vista, you must now have Service Pack 1 installed.
