Hey Grant,
Like Jason mentioned, the
list of changes is here. 0.5 is the version to get with the fixes for the memory leaks. 0.5 was the biggest release so far and brought in the
unit tests and fixes to some other reported bugs. 0.6 is the currently release with a Interceptors, Reactions and ModuleGroups.
When I started, Fabrication was just the routing layer on top of pipes. The scope of the project has since changed as I have added features that I think are needed to program in PureMVC in a more efficient manner. Initially I tried to do things from a pov of a PureMVC utility. However features like Reflexive Mediator registration and Interceptors can not be done without extending the core PureMVC actors.
Fabrication will continue on this path and add any features that are useful to general PureMVC development. I will maintain compatibility with PureMVC and any of its utilities as long as it makes sense. Nevertheless It would be nice to be officially linked from the PureMVC site. It is released under the Apache license, and any code contributions are welcome. ;-)
peace,
darshan
