He also closed down the official forum, which was overrun with spam. I was one of the moderators there, and basically the other mods and I had given up on trying to keep the place clean (the forum software needed to be updated), and the forum wasn't being used for much anymore, so we pretty much packed up and left. A few members of the old forum started up their own Quintessential Community Forum, though there's not a lot of activity there, and almost no discussion of QMP.
Anyway, that's pretty much where things stand today. Personally, I've moved on to using MusicBee as my main music player. I know some former QMP users who now use AIMP, and then there's always ol' Winamp. But of course, if QMP still works for you and covers all of your needs, you're free to keep using the final version as long as you like.
