Amarok 2.2 RC 1 was released a few days ago. For complete changelog, visit this page.
I loved Amarok 1.4 and even used it in Gnome. Then, I really hated all the 2.x series until this 2.2 RC1. It's kind of slow, but it finally looks like a real music player and reminds me why I liked Amarok so much. I'm currently using it in Ubuntu Jaunty and since there are only .deb files for Ubuntu Karmic posted on the announcement download link (actually those are for version 2.2 beta), I thought I'd let you know how to install it in Ubuntu Jaunty.
