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.

Note: For the beta, the new features are only presented in English. The final release will have complete translations for the other supported languages
New: Soften Portrait effect, by David Issel
New: Ink Sketch effect, by David Issel
New: DirectDraw Surface (DDS) file format support, by Dean Ashton. Improved from the original source code by optimizing the DXT compression library ("Squish") to take advantage of multiple cores or processors
Improved: Visual fit-and-finish for the Layers window
Improved: Visual fit-and-finish for the close / 'X' button on image thumbnails
Changed: The keyboard shortcut key for the Color Picker is now 'k'. This makes it so that the toolbar option, "After click: Switch to previous tool", is not useless for those using the keyboard shortcuts
Fixed: Pressing Ctrl+[ no longer cancels out of drawing a line/curve, but instead decreases the brush size by 5 as expected
Fixed: Ctrl+clicking on the brush size +/- buttons now changes the brush size in increments of 5
Fixed: Save Configuration dialog would "creep downward" from its last position every time it was opened again
Fixed: TGA codec now saves the # of alpha bits to the image descriptor byte. This was causing some other applications to load TGA files saved with Paint.NET as solid black images
Fixed: Clicking the 'X' to close the Layer Properties dialog was not reverting changes made to the layer while the dialog was open
Fixed: Installation will not proceed unless Paint.NET is closed, and will also not allow Paint.NET to be opened until installation is completed. This helps to ensure a fully coherent and complete installation or update
Fixed: In Vista, it was possible to crash the Save As dialog by typing a filename that was too long
Fixed: In Vista, it was possible to crash the updater if you let the UAC prompt time-out
Fixed: It was possible to crash Paint.NET on some systems by clicking on a tool in the Tools window while the "Save As" dialog was open
