Mobile app release process

The Mattermost Mobile Apps team works on a monthly release process, with a new version submitted to the iOS App Store and Google Play Store on the 16th of each month.
Please refer to the Mobile Release Playbook for a most up-to-date checklist.
Note: iOS App Store approval may take a few days after the 16th.

Release Timeline

Note: T-minus counts are measured in "working days" (weekdays, Monday through Friday, excluding the listed statutory holidays) prior to release day.
Schedule for Mobile App releases:
  • Around T-14:
    • This is the Feature Complete deadline for the release.

    • Cut RC builds based off the release branch for QA release testing. Release testing begins.
  • Code Freeze at T-5
    • Cut another RC build based off the release branch.
    • Note: More frequent RC builds may be requested by the QA team and the Release Manager as we get closer to the release date and as more regression fixes get merged.
