The RAW (written) have been stable and updated at Final Edition since before that time. There has been updates since for the Collector Edition that are not implemented in MWIF.
The RAC (coded) are the specifications for the implementation of the written rules into code. Those are also stable and though they could be changed, they are an interpretation of the written rules, they do not need to be changed.
So, everything, in this regard, is fine. At this time, there are no plans to change anything to re-implement the Collector's Edition.
Personally, I do not think that will happen any time soon. Priorities are to complete correcting the application to match the FE RAC/RAW, implement remaining optional rules, remaining one-map scenarios, and Artificial Intelligence for a couple scenarios - not likely for the Global War, but who knows for certain?
