Here is an update for 8.0.x builds: 8.0.2, build 27482.
It contains lots of fixes and is compatible with the recently released ReSharper 8.0 (via TeamCity add-in for Microsoft Visual Studio).
Upgrade is highly recommended as there are several important fixes affecting server performance, functioning of several web UI pages, version controls integration and others.
The version uses the same data format, so transparent upgrade/downgrade is possible within all the 8.0.x builds.
So get the release now and make your servers happy :)
