Bcfg2 1.3.0pre2 is a prerelease, and contains many new features, including some that are backwards-incompatible with Bcfg2 1.2.x and earlier. The code is fairly stable, but this is a prerelease and as such is not likely suitable for general production deployment. That said, please help us test the release in non- and preproduction environments.
