Summary

A school's Mattermost instance with over 2,000 active users and 470,000 posts is experiencing a problem after a new upgrade where a 10,000-message limit has been reached, causing messages sent before September 26, 2025 to become hidden and inaccessible. The user is asking when this hard restriction was implemented (possibly in v11) and whether September 26 is a calculated date based on the 10,000 message limit or simply provides access to recent months of messages.
