We added initial support for virtual agents based on Amazon EC2 service. Right now such agents must be started manually and there is no UI for configuration editing.
The process of creation of Maven build configuration is significantly simplified. All you need is an URL to your project pom file, the rest will be done by TeamCity. By default Maven version number and TeamCity build number will be synchronized too.
Also for Maven build configurations the new tab "Maven" is added which displays all significant information from the Maven project.
We added backup & restore to simplify TeamCity maintenance. Also the migration tool was re-implemented.
Right now backup can be started manually only, but we plan to improve it in the next EAP versions. Most likely it will be possible to start backup using HTTP request. Restore can be done from the command line only.
Now for every agent you can see a history of the builds this agent executed. This was the one of the most voted features in our tracker. Finally we've closed this issue. Enjoy
Coverage statistics diff against previous build is now shown for the builds with coverage information gathered. Also ability to sort by columns was added to Java coverage report (IntelliJ IDEA coverage only).
