I don't see any change in header.
I can't see any difference either.
Hey.
Maybe, we are getting
advance notification of a web site change.
That guy said advanced notice

All this makes me seriously concerned about the lack of QA and proper release schedule. It would benefit everyone if new features would be announced and put out for public feedback in advance. Frontend/GUI changes that don't affect mining could be open for public testing before releasing to production. I understand that ultimately this is not a democracy but some transparency can go a long way towards everyone's satisfaction and profits.
Advanced notice makes people want to try the pretty new things that don't exist yet
