I feel this module is ready for serious use. I have been using it in production environments for almost 2 years now, and I have recently beefed up the test suite as well. It now has 371 tests with approx. 95% code coverage. I feel the code is solid as is the API (although some people dont like my Java-esque naming style, but hey whatta ya do). Most of this release is just tweaking and fine tuning of code, and updating of the documentation.
