In preparation for the new major release, Drupal 10.0.x and Drupal 9.5.x will enter beta the week of September 12, 2022.
Core developers should plan to complete changes that are only allowed in major releases before the beta release. The Drupal 10.0.0-beta1 and Drupal 9.5.0-beta1 deadline for most major patches is September 9, 2022.
Developers and site owners can begin testing 10.0 and 9.5 once the beta versions are released.
During the beta phase, major issues are committed according to the policy on changes allowed during beta.
Most issues allowed for patch releases will be committed in 10.1.x and moved to 10.0.x, 9.5.x, and 9.4.x.
Most issues that are only allowed in minor releases will be committed only to 10.1.x. Some strategic issues (such as PHP 8.2 or Symfony 6.2 compatibility fixes) may be backported to 10.0.x and 9.5.x, but only at the committer's discretion after the issue is fixed in 10.1.x (so please leave them set to 10.1.x unless you are a committer), and only until the release candidate deadline.
The 10.1.x kernel branch has already been built, and future features and API additions are already targeted to that branch instead of 10.0.x.
More beta versions may be available as needed.
The Release Candidate phase will begin the week of November 14. See the Drupal 10.0.0 requirements for issues required between 10.0.0-beta1 and 10.0.0-rc1 or 10.0.0.
The scheduled release date for Drupal 10.0.0 and 9.5.0 is December 14, 2022.
