Announcements are pointless. The game is long-term and announcements vanish after a short while.
The wiki is the proper place for the game "memory". Oh, and look: http://wiki.battlemaster.org/wiki/Rules_and_Policies
The Rules don't and shouldn't change often.
The point that was made is that a list of current bugs would be useful. It's hard to know you're exploiting a bug if you don't know it's a bug. This is a good point, regardless of whether the current case is seen as a violation of the Rules or a bug exploit or just a bug.
