We've fixed some bugs the past few weeks, and not every change is noted in these updates. I know of a few MediaWiki messages that were added because they were "missing", but the biggest recent change would probably be last week's increase in the number of threads displaying at once on a board page. Nothing that should have made any new buttons show up, though. Send in some details to Special:Contact and we can discuss any specific questions you have.
