This change was announced by Matt during his State Of The Word presentation at WordCamp San Francisco this weekend, and was overwhelmingly positively received. In fact, it was so well received that this week’s dev chat (Wednesday, October 29, 2014 21:00 UTC+1) will be hosted in the WordPress #core channel on Slack, rather than in the #wordpress-dev channel on IRC.

There will be volunteers hanging out in #wordpress-dev to inform users that the dev chat has moved to Slack. For those of you who don’t want to leave IRC just yet, you can connect to WordPress Slack using the IRC gateway.

The #core and #announcements channels on Slack have just surpassed 1,000 users, which is five times as many as we’ve ever had in the channels on IRC. Join us at chat.wordpress.org!
