My other personal favourites of this release include transcoding at more places and crucial bug fixes so that Amarok doesn't loose your ratings and stuff when it doesn't have to. This is just one item of the multi-page long list of fixed bugs.
In short, Amarok 2.6 shines like never and is an absolute must for you. :-) Do you like it? Me and other awesome Amarok & KDE volunteer hackers will meet in Switzerland's Randa to code, discuss and plan immersely, please consider donating to help us cover the expenses. Thanks!
