A huge piece of work was done on rewriting BuddyPress Groups Extas plugin. Nearly 70% of the code was modified and improved. Plugin admin area was changed dramatically. But the main change is the code clean-up and preparation for extending the plugin.
Very soon several new features will be added, that will give ability for site admins to have even better control over the groups: access levels, per group features management and lots of other things. The plugin now supports WordPress built-in caching. And it will become even more configurable.
Currently I think about taking BP: Extend Groups Description functionality into BPGE.
