WordPress 5.0 will be the major release of 2018, including the new block editor, and the Twenty Nineteen theme.
|November 15, 2017||Trunk is open for business. (Post-4.9)|
|October 3, 2018||5.0 Kickoff meeting.|
|October 19, 2018||Beta 1 and feature merge deadline.|
|From this point on, no more commits for any new enhancements or feature requests in this release cycle, only bug fixes and inline documentation. Work can continue on enhancements/feature requests not completed and committed by this point, and can be picked up for commit again at the start of WordPress 5.1.|
|October 30, 2018||Release candidate and soft string freeze.|
|November 12, 2018||Final release candidate if needed and hard string freeze.|
|November 18, 2018||Dry run for release of WordPress 5.0 and 24 hour code freeze.|
|November 19, 2018||Target date for release of WordPress 5.0.|
The next WordPress 5 release date is scheduled on 19th of November 2018 (+ plus 8 days are as a backup if necessary). But this isn’t strict deadline, because developers openly count on the option that they won’t be fast enough with all bugs fixing.
So if they will expect, that it is not a good idea to release WordPress 5 by the end of November/ beginning of December, they have another target date for release – January 22, 2019. See:
