Here is a new update for the stable TeamCity version 7.0, build 21424 awaiting for your downloads.
It has some recently discovered bugs fixed and includes several performance improvements, mostly related to processing of large build chains. See the full fixed issues list.
The server still uses the same data structure format, so you can downgrade to any of 7.0.x, if necessary.
While you download the distribution, can you think of your "dream feature" for TeamCity?
