New Release Information

This release, and all releases going forward are going to be made available using a different approach with regards to what is going to be included. The goal is to ensure that we maintain a predictable monthly release cycle which is becoming more challenging with the increased rate of feature requests.

Please expect to see fewer backward compatible features being introduced into the patched releases (e.g. 2.0.11). These features, along with features that may include incompatible changes, will be grouped and added into minor releases (e.g. 2.1) or major releases (e.g. 3) depending on the nature of the changes.
