So I don’t know if you noticed, but WordPress 3.5 dropped. All hands on deck for all the cries.
Forum moderators are updating https://wordpress.org/support/topic/troubleshooting-wordpress-35-master-list as soon as we find issues (as well as telling Nacin). We’re going to be active in #wordpress-sfd all week with the codex and the forums.
Please come by IRC or the wp-forums mailing list if you want to help out with the wrangling of the madness. (Yes we will have our normal chat this week. It’ll likely be a ‘what broke?’ office hour 😉 )
