Mobile app release process

The Mattermost team works on a monthly mobile app 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 the release 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.

The Mobile app release schedule follows the cloud/self-hosted release schedule to align all release testing cycles.
