This release fixes several outstanding issues with 1.8.
µTorrent will never exceed the half-open limit now. This resolves the issue where trackers would all go offline after a few hours and require restarting µTorrent. It also connects to as many peers in 1.7.7 in all circumstances, as the connection distribution system has been fixed.

Furthermore, the crash on Vista has finally been resolved!

We've worked around the NOD32 issue, but it's still a nasty bug in NOD32 2.5/7 and you should really not use IMON, as the issue could potentially affect any program.

The update tracker restriction has been relaxed when the announce fails. If the announce fails for any reason, you'll only have to wait 60 seconds to do manual update tracker again, instead of whatever the min interval actually was.

Final version-first topic

Note: 12639 is out and on the automatic updater for all users. The only fix is to prevent µTorrent from showing the installer dialog when upgrading from an older version. There are no other changes, and if you are already on 12616, there is no reason to update.
Tracker admins, please allow both builds (12616 and 12639). The user-agent is identical for both.
