Mattermost 5.36: Important upgrade notes
@twk3 Below is a note of important upgrade notes in our upcoming release.
Mattermost v5.36 (GitLab 13.14 - July 22)
- Gossip clustering mode is now in General Availability and is no longer available as an option. All cluster traffic will always use the gossip protocol. The config setting UseExperimentalGossip has no effect and has only been kept for compatibility purposes. The setting to use gossip has been removed from the System Console. Note: For High Availability upgrades, all nodes in the cluster must use a single protocol. If an existing system is not currently using gossip, one node in a cluster can't be upgraded while other nodes in the cluster use an older version. Customers must either use gossip for their High Availability upgrade, or customers must shut down all nodes, perform the upgrade, and then bring all nodes back up.
