I checked Their repository, and its last release was about 3 years ago, with only three 1/2 years old issues still open. And Wikipedia also confirms that.
Is this project still actively maintained or developed? Does anyone use it or recommend using it?
Well, but I don’t see any nightly builds even. Or any repo package with latest build. Even Arch package version of Calligra is the latest 3 years old release.
So, the only way to use Calligra with the latest commit is to download the source and compile it yourself. And You know that it’s not going to be a happy compiling.
