We are at the point right now where major happenings are already announced in the NEWS forum. Other happenings, of course, can be derived from the Change Log from MAMETesters, which will list a log of fixed bugs. If you can also monitor GIT commit logs to be aware of other happenings. MAME has never been more transparent than it is now.
The wild early days of emulation have passed where numerous major additions were being made daily. That level of progress will never be again - so a WIP blog isn't a high priority.
