What’s next?
Reminder: the dev-reviewed workflow (double committer sign-off) is required when making changes to the 6.9 branch A directory in Subversion. WordPress uses branches to store the latest development code for each major release (3.9, 4.0, etc.). Branches are then updated with code for any minor releases of that branch. Sometimes, a major version of WordPress and its minor versions are collectively referred to as a "branch", such as "the 4.0 branch"..
The final release is expected on Tuesday, February 3, 2026. This date is subject to change if any issues with RC1 are discovered. Coordination will happen in the WordPress.org The community site where WordPress code is created and shared by the users. This is where you can download the source code for WordPress core, plugins and themes as well as the central location for community conversations and organization. https://wordpress.org/ Slack Slack is a Collaborative Group Chat Platform https://slack.com/. The WordPress community has its own Slack Channel at https://make.wordpress.org/chat/. #6-9-release-leads channel, and releases are always packaged and tested in #core.
A special thanks to everyone who reported issues, helped test, and helped create patches. The success of 6.9.1 depends on proper testing, so please lend a helping hand.
Props @wildworks, @joedolson, @westonruter for pre-publication review.
