I believe they announced they were focusing on the site again a few months ago.

These small changes are using existing code or small things (like their update pointed out) that were submitted by the community or can be easily included in the next HF that will merge the worker proposal system.

All changes are also preparing for communities and with hivemind, more should be possible more easily.

I think their main focus is still blockchain level - hivemind, MIRA, then communities and then they are just trying to solve some of the “low hanging fruit” stuff when they can.. the easy stuff. Haha.
