Krita 5 was released just before Christmas 2021 and had its first bug fix on the 7th of January 2022 bringing it to the current version 5.02.
Krita is a free open source digital painting program which also has animation features. There were a lot of updates in version 5 of the program which you can read about in detail here on the official website for Krita.
The main features I was personally interested in were the improvements to the smudge painting engine and the ability to use it with the RGBA brushes. It gives a lovely oil painting sort of feel.
I have already made several images with the new version of Krita, including one of a red Siamese Fighting fish which I gave them permission to use in the promotional video.
