NOTE:
The beta versions are available as a means for delivering bug fixes and feature requests without
the required rigor of a full product release. These may contain new bugs or proof-of-concept features that could
prevent you from accessing functionality of previous versions. Because of this, we encourage the use of stable
releases that have been more thoroughly tested.
