I don't know how Bitovi can bash other frameworks for breaking compatability on major versions, when they completely changed the concepts of JMVC in version 3.3. They also stagnated for 2 years between version 3.2 and 3.3.

>If your project chose JavaScriptMVC in 2007, you would have made a wise decision, giving your team an upgrade path to a modern application for the past 8.5 years.

This is kinda funny to me because I know it's untrue. The product I work on in my day job is based on JMVC 3.2 and we can't upgrade to 3.3 because of the size of our app and the amount of refactoring work that would need to be done to make it work with the new concepts.
