For those who aren't aware, today here at BADCamp, Drupal 7 at long last reached 0 critical issues! YAY!!!
We also released Drupal 7.0 beta 3. Why beta3 and not rc1? Please click the link for more details. :) (Spoiler: We wanted to leave room for one last hash through the "majors" queue and pre-string freeze clean-up)
So if you're a core subsystem maintainer, please try and find some time in the next day or so to triage your issue queue and make sure that we're not sitting on any release blockers we don't know about yet. Drupal 7 RC1 represents an "everything freeze", and is imminent.
