Support for Extended Support Release 6.3 is ending
Upgrade to ESR 7.1 for improved security and performance, mobile app compatibility, and enhanced user experience
As of October 15, 2022, Mattermost Extended Support Release (ESR) version 6.3 will no longer be supported. If any of your servers are not on ESR 7.1 or later, upgrading is recommended.
Extended Support Releases are releases that will receive backports for high severity or high impact security fixes for the length of their lifecycle. Mattermost provides an ESR when a significant number of new features and improvements have been added to the product and when those new features have had sufficient time to stabilize.
ESRs benefit organizations that value stability over having the newest features and improvements or those that have a long internal testing and certification process to undergo when upgrading. Mattermost designates two releases every year as ESRs, one in January and one in July. We support each ESR version for nine months to provide you with enough time to upgrade to the next ESR.
ESR v7.1 is supported until April 15, 2023.

2. Mobile app compatibility
As we innovate and offer newer versions of our mobile apps, we maintain backwards compatibility only with supported server versions. Users who upgrade to the newest mobile apps while being connected to an unsupported server version can be exposed to compatibility issues, which can cause crashes or severe bugs that break the core functionality of the app.
3. New features and improved user experience
We add new features and user experience enhancements to our new versions every month. See our changelog for a full list of the latest features, performance enhancements, bug fixes, and other improvements.
