Paint.NET 4.2.9

February 1, 2020

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.

Thanks to KXR75 for the update.

Gentle reminder:

Minimum System Requirements

Windows 10 (version 1607 "Anniversary Update" or newer), Windows 8.1 or Windows 7 SP1 with Platform Update
1GHz processor (dual-core recommended)
1GB of RAM

Paint.NET depends on minimum Microsoft's .NET Framework 4.7.2 , which is automatically installed (Paint. NET will conduct online installation of 4.8 instead of 4.7.2, as 4.8 is much more newer) if it isn't already on the system.

This update improves performance and significantly reduces memory usage, adds two new translations, and fixes a number of small issues.

If you’re using the Windows Store release, you should get the update automatically within the next 24 hours. You can also force an update check by following these instructions.

For the Classic release, you should be offered the update automatically within the next week or so. You can get the update sooner by going to ⚙ Settings → Updates → Check Now. You can also download and install it directly from the website.

Changes since 4.2.8:

Reduced overall memory usage (commit size) by up to 1/3rd by eliminating the per-image scratch buffer
Greatly improved performance when finishing actions of most tools by employing a shared cache between the render and commit code paths
Reduced memory usage when working with many tools by consolidating homogenous tiles (those that are comprised of a single color value)
Significantly improved performance of most history actions (commit, undo, redo) by switching from NTFS compression to multithreaded LZ4 compression for history files
Significantly improved performance of undo/redo with very complex selections (e.g. from the Magic Wand tool)
Improved performance of Image -> Flatten (also affects flattening when saving)
Improved performance of the Invert Colors and Desaturate adjustments by disabling hardware acceleration for them (too much overhead in copying tiles to the GPU for such trivial rendering kernels)
Improved performance when saving by moving thumbnail rendering for the File -> Open Recent menu to a background thread
Reduced memory usage when printing, and removed a rare crash that was related to its use of the (now removed) scratch buffer
Improved performance of effect rendering when a complex selection is active (improved caching)
New: Added a "busy spinner" to the canvas when using the Magic Wand and Paint Bucket tools
New translation: Hebrew (HE)
New translation: Slovak (SK)
Fixed a really goofy crash that required drawing with the paintbrush and, without letting go of the mouse button, moving the mouse into the toolbar and then using the mouse wheel to change the brush width
Fixed a layout bug with the image list button
Fixed an error that prevented saving some images as JPEGs if they had EXIF Interop metadata (PropertyNotFoundException)
Fixed a crash when running on a CPU that supports AVX but with an OS that is configured to not support it (via bcdedit /set xsavedisable 1)
Fixed a crash when pressing the spacebar after switching to a tool but before it has received any mouse input events
Fixed a rare crash when opening the Levels adjustments with certain types of selections
Fixed a crash when checking for updates with an expired alpha/beta build
Fixed a crash (FileLoadException) when DLLs are not updated correctly by the updater
Updated WebPFileType plugin to version 1.3.2 (thanks @null54!)
Updated DDSFileTypePlus plugin to version 1.9.9. This adds support for X8B8G8R8 and R8G8B8 formats, and fixes a visual glitch when previewing cube maps in some formats. (thanks @null54!)
