I have the same question! I also noticed the hard limit before was 5000 users.
Hardware requirements for team deployments
Most small to medium Mattermost team deployments can be supported on a single server with the following specifications based on registered users:
1 - 1,000 users - 1 vCPU/cores, 2 GB RAM
1,000 - 2,000 users - 2 vCPUs/cores, 4 GB RAM
And hardware requirements indicate that 1000 users is easily supported by a tiny vm, so not sure how it’s being justified that performance degrades past 250 users.
Could you kindly confirm in which version the 1,000-user limit was introduced for the Team Edition?
The changelogs seem to mention the 5,000 limit in v10.6, but I haven’t seen any official note about when it dropped to 1,000.
