New gtk3 beta : gmusicbrowser- (released on 30-07-2020)

gtk3 beta for debian/ubuntu

Important: It's currently best to use the git version, either the master branch (beta version using gtk3) (latest zip snapshot) or the v1.1.x branch (latest version using gtk2) (latest zip snapshot). It's very easy, just download the zip snapshot, unzip, and run "perl". The gtk3 version has some sizing and icons problems but is otherwise very usable and stable, though you will need different libraries than for the gtk2 version. You can currently switch back and forth between the gtk3 and gtk2 version with no problem.
