aMSN 0.98.3 has just been released. It contains several bugfixes, the most important one being that nicknames aren’t reset to the one associated with your Passport account when you connect anymore.
Unfortunately, Audio/Video support was also dropped, as explained in this previous post.
For Linux users, autopackage support was dropped as well, since the autopackage project seemed to be dead and most distributions already supply aMSN anyway.
Fetch your copy of aMSN now, and have fun!
