Mattermost server v9.11 has been implemented as a new Extended Support Release in August, 2024. v9.11 will be supported until May 15, 2025. We have been maintaining v9.5 as our current ESR. This version has come to the end of its life cycle. Starting November 16, 2024 we will no longer backport fixes to v9.5. Please upgrade your systems to v9.11 as soon as possible to continue to receive important bug fixes and security updates and to maintain mobile compatibility.
Additionally, from August 2024, Mattermost server extended releases are now paired with Mattermost desktop app extended releases. Mattermost Desktop App v5.9 has been implemented as a new desktop app Extended Support Release in August, 2024, and will be supported until May 15, 2025.
Extended Support Releases or ESRs are a strategic choice for organizations looking for stability and reduced frequency of updates. Using ESRs can minimize disruptions associated with frequent upgrades, making them an attractive option for environments where stability is paramount.
