The dot versions are released to correct bugs, and that is what KDE is doing with its program created by and for cartoonists. The previous 4.4.7 fixed 7 bugs, and Krita 4.4.8 has come to correct only two more. This release comes shortly after the project has released the Krita 5 Beta, so it stands to reason that they are focusing on the next release, which does not mean that they are going to leave the existing with annoying glitches.
And it is that in the short list of news, which is rather a paragraph with the two changes, a bug that made it impossible to save a file as .kra, which could lead to data loss. Losing information is not a small bug, so KDE has decided to release this update to fix it.
What's new in Krita 4.4.8
This is strictly a bug fix version. There are two changes: we have fixed an issue when saving a .kra file with an embedded palette, which would break and cause data loss, and for Windows, support for fractional HiDPI screen scaling is now disabled by default.
This time there has not been an intermediate launch to take to any store like Epic's, something that did happen in versions 4.4.6 and 4.4.4. Out of stores, Krita 4.4.8 It is now available for all supported systems from your download page. From there, Linux users can download a AppImage, but a repository for Ubuntu is also available (https://launchpad.net/~kritalime/+archive/ubuntu/ppa) and they give us a link to download the program from Flathub, although at the time of writing the package flatpak is in the v4.4.3. Although it is not mentioned there, it is also available as snap pack, but it is not updated to this version either, so right now it can only be used from its official AppImage or PPA.
