JetBrains has released TeamCity 5.0, a $1999 payware continuous integration server. TeamCity manages builds and can be configured not to check in code unless tests pass. "This release brings a huge potential improvement in scalability by reinforcing its distributed build grid with Amazon EC2 cloud integration. Features such as build configuration templates, project archiving, and backup&restore eliminate unnecessary redundancy and hassle in configuring large build infrastructures. To make TeamCity feel at home everywhere and benefit developer productivity, we've added issue tracker integration, better support for Maven, Command line tool for personal builds, and many other features."
