Paint.NET is image and photo manipulation software designed to be used on computers that run Windows. It supports layers, unlimited undo, special effects, and a wide variety of useful and powerful tools. It started development as an undergraduate college senior design project mentored by Microsoft, and is currently being maintained by some of the alumni that originally worked on it. Originally intended as a free replacement for the MS Paint software that comes with Windows, it has grown into a powerful yet simple tool for photo and image editing. The programming language used to create Paint.NET is C#, with a small amount of C++ for installation and shell-integration related functionality.

- Performance in many areas has been substantially improved, and overall memory usage has also been greatly reduced (especially when more than 1 image is open).
- The user interface has been refreshed with new icons, and visual styling has been enhanced for Aero Glass (Windows 7 / Vista only).
- Upgraded to use the latest .NET Framework 3.5 SP1, which has many built-in performance improvements.

- The font manager for the Text Tool has been completely rewritten, resulting in increased performance and better reliability. On Windows 7, the quality of text is much better as a result of using DirectWrite (this also works on Windows Vista if you have installed DirectX 11).
- The built-in updater now has the ability to download updates in the background, and will wait until you exit Paint.NET to install them. In previous versions, the download happened in the foreground, and you had to wait for the entire process to complete before you could use Paint.NET again.
- Now includes a Russian translation.
- Fixed the gamma and contrast for text rendering on some systems where the wrong values were being used ("rainbow" text)
- Colors window now correctly lets you paste a hex color value that starts with a hash, e.g. #112233
- Gradient tool now lets you reverse a transparency gradient by clicking the right mouse button on one of the handles (regression from 3.5)
- Move Selected Pixels now lets you hold Control to leave a copy of the selected area behind on the initial move (regression from 3.5)
- Paint Bucket toolís hatch fill modes werenít working with the Overwrite blending mode (regression from 3.5)
- Fixed a keyboard tabbing issue in the Resize dialog (regression from 3.5)
- Fixed the language setting in the Settings dialog not always allowing you to set it to English if your systemís default language is non-English
- Fixed a performance issue that caused images with many layers (50+) to take a VERY long time to open, close, or even switch away from (regression from 3.5)
- Fixed a rare crash at application exit
- Fixed an issue that prevented 4.0.1 from installing on top of 4.0 when using the MSI (e.g. AD/GPO network deployment)
- Fixed an issue that would sometimes cause the installer to take 30+ seconds to appear
