ScalaTest 2.1.3 is a maintenance release for the 2.1.x series that includes five enhancements and a bug fix. No source code using ScalaTest 2.0+ should break, but you will likely need to do a clean build to upgrade from 2.0. However, 2.1.3 is binary compatible with 2.1.0, 2.1.1, and 2.1.2, so you can just change the version number in your build to upgrade from earlier 2.1.x releases.
