I know that a 6.4 upgrade involves restructuring things out of etc, but what I can't figure out from Adobe's repository restructuring documentation is if 6.5 introduces any additional restructuring changes to etc. The restructuring docs for 6.5 appear to have the same info as the 6.4 restructuring docs. So did all of the etc restructuring happen in 6.4? Are there 6.4 features that use etc that are no longer supported in 6.5? Any background on how aggressive Adobe is deprecating etc would be helpful.
