Just a quick heads up: the next update, version 4.0.20, will start using and requiring the .NET Framework 4.7 (previously, .NET 4.6 was required). If you’re using a supported version of Windows then the Paint.NET updater will automatically install .NET 4.7.1 if you don’t yet have .NET 4.7 or .NET 4.7.1 installed already.
This does mean that the list of supported operating systems is changing slightly because of .NET 4.7’s updated system requirements as compared to .NET 4.6.
Windows 10 support will now require the “Anniversary Update” (1607) or newer. “RTM” (1507) and “November Update” (1511) will no longer be supported.
Windows 8.1 is still supported.
Windows 8 is no longer supported because .NET 4.7 won’t install on it. If you have Windows 8 and haven’t yet updated to 8.1, then 1) please just install the update already, and 2) why on Earth haven’t you already updated (it’s been more than 3 years!). You can also just keep using Paint.NET 4.0.19. But, seriously, just install the 8.1 update already. Even better, upgrade to Windows 10.
Windows 7 SP1 is still supported.
For more information on the .NET Framework’s system requirements with respect to supported Windows OS versions, check out Microsoft’s page on the subject.
I expect to publish 4.0.20 within the next few weeks. It will have, as usual, some important bug fixes. Oh, and Explorer thumbnail support for DDS and TGA files.
