-After 7th at 23:59 (Pacific Standard Time Zone) of each month, RC1 of the upcoming release (to be shipped on the 22nd) is created and deployed to GitLab.com and the stable branch for this release is frozen, which means master is no longer merged into it.

 Merge requests may still be merged into master during this period,
 but they will go into the _next_ release, unless they are manually cherry-picked into the stable branch.

+This feature is available for merge requests across forked projects that are

+on merge requests across forks.
+
+When enabling this feature for a merge request, you give can give members with push access to the target project rights to edit files on the source branch of the merge request.
+
+The feature can only be enabled by users who already have push access to the source project. And only lasts while the merge request is open.
