JetBrains has released TeamCity 1.2, a semi-IDE independent continuous integration server. TeamCity manages builds and can be configured not to check in code unless tests pass. (This is actually a quite bad idea, for reasons I've outlined elsewhere. Refusing to commit failing tests is simple denial. Admitting you have a problem is the first step toward fixing it.) Version 1.2 adds support for Visual Source safe and fixes a host of bugs. TeamCity is $399 payware.
