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 configurations is significantly simplified. All you need is to provide URL to your project pom file, the rest will be done by TeamCity. By default Maven version number and TeamCity build number will be set to be in sync.
Also for Maven build configurations the new tab "Maven" is added which displays all significant gathered 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 allow backup starting by HTTP request too. Restore can be done from the command line only.
If your build has artifact dependencies to other build configurations then in the Run custom build dialog you can now choose concrete builds to depend on.
Or you can do the same the other way. Go to a build which artifacts you want to use, choose "Promote..." action from the actions menu and start a build depending on this build by artifact dependencies.
These features are useful for various Deploy/Install/Publish-like configurations.
