Users of the free image editor Paint.Net may have received up to three updates in the past two days for the program on supported Windows installations.

The developer of Paint.Net released version 4.3.5 of the program on January 3rd. Paint.net 4.3.6 was released on the same day to address a crash in the application, and Paint.Net 4.3.7 followed a day later, which addressed a bug in .NET 6.0.1.

Windows users who have the desktop version of Paint.Net installed will receive the latest version, Paint.Net 4.3.7, when they run the check for updates now.

Here is what happened in the past two days. Paint.net 4.3.5 was released on January 3rd as a regular update for the image editor. It included the rendering performance improvements for most tools, which, according to the developer, improve the rendering speed by up to 100% when compared to previous versions of the application.

The remaining changes of the release were bug fixes that addressed a total of eight issues, including a save configuration dialog issue affecting Windows 7 systems and several plugin compatibility issues.

A hotfix was released on the same day to address a "crash in the box filter rendering kernel, which is used to generate mip-maps for the canvas when zoomed out". The crash had very specific parameters, as indicated in the changelog:
Fixed a stack overflow in the box filter rendering kernel that could cause hangs or crashes when the zoom level was around 1/8th (12.5%) or 1/32nd (3.125%) for particular image sizes e.g. ((N x 2048) + 16))

Paint.net 4.3.7 was released a day later. It was another hotfix release, this time to address "myriad issues when 'translucent windows" is disabled". Transluscent windows is enabled by default, but users may disable the feature in the settings under User Interface.

The issue was caused by a bug in .NET 6.0.1 according to the developer, and quickly resolved. Users who download the latest version from the official website or use the built-in update functionality will receive the latest version with the fixes.

Paint.net 4.3.8 is likely the last version for Windows 7 and Windows 8.1​

The developer of the popular Paint.net image editor has released Paint.net 4.3.8 to the public on February 16, 2022. The new version marks the end of the 4.3.x branch of the application and support for Microsoft's operating systems Windows 7 and Windows 8.1.

The next major version of the image editor, Paint.net 4.4, will support 64-bit or ARM devices running Windows 10 and later only. While there is a chance that a bug fix release will become available before Paint.net 4.4 is released, users of the application who use it on Windows 8.1 or older devices won't be able to upgrade to Paint.net 4.4 once it is released by the developer.

Paint.net 4.3.8 installs fine on all supported devices. Users can download the latest version from the project website or the Microsoft Store. Paint.net users may also select the question mark icon in the Paint.net interface and then about to display the current version of the application and run a check for updates.
