How it works

[low] When a JIRA issue is ready for merging, its fixVersion/s field changes from the generic “Backlog” placeholder to a target release version; changes are usually first merged to the master branch, so the first tagged fixVersion is typically a development/unstable release. Sources: https://www.mongodb.com/community/forums/t/when-will-server-25023-be-released/1340 [source]
[low] After merging to master, changesets are considered for backport to non-EOL production release branches depending on impact and complexity, with additional releases added to the fixVersion/s field as backports are completed; however, backports may not always be possible or approved if server code has changed substantially or the changeset introduces risky or backward-breaking behavior. Sources: https://www.mongodb.com/community/forums/t/when-will-server-25023-be-released/1340 [source]
[low] A JIRA issue is in Code Review status when the assignee has submitted a changeset for internal code review. Sources: https://www.mongodb.com/community/forums/t/when-will-server-25023-be-released/1340 [source]
[medium] SERVER-118428 relates to mongocryptd rejecting large messages, caused by recently reduced pre-auth message limits; drivers do not authenticate to mongocryptd because it is expected to run alongside client applications. Sources: https://jira.mongodb.org/browse/SERVER-116495, https://jira.mongodb.org/browse/SERVER-118428 [source]

Problems, failure modes and limitations

[low] Deprecated MongoDB usage metrics include mongodb.usage.commands.count, mongodb.usage.getmore.count, mongodb.usage.insert.count, mongodb.usage.queries.count, mongodb.usage.readlock.count, mongodb.usage.remove.count, mongodb.usage.total.count, mongodb.usage.update.count, and mongodb.usage.writelock.count, all tracking counts since server start. Sources: https://docs.datadoghq.com/integrations/mongo/ [source]

Facts and statements

[low] mongocryptd 8.0.17 is OK, but mongocryptd 8.0.18 fails and logs errors; a driver test started failing on server 8.0.18 and 7.0.29. (verified as of 2026-10-15) Sources: https://jira.mongodb.org/browse/SERVER-118428 [source]
[low] The MongoDB Shell (mongosh) and MongoDB Database Tools are released separately from the MongoDB Server and use their own version numbering systems. Sources: https://www.mongodb.com/docs/manual/reference/versioning.md [source]
[low] The serverStatus counter for write-blocking enabled with the reason DiskUseThresholdExceeded tracks the number of times it was enabled since the server started. (The metric name mongodb.usage.writeblocking.count does not appear in the cited source.) Sources: https://www.mongodb.com/docs/manual/reference/command/serverStatus.md [source]
[low] The issue affects versions 8.2.4, 8.0.18, and 7.0.29, with backports requested for v8.2, v8.0, and v7.0; fix versions include 8.3.0-rc0, 8.0.20, 7.0.31, and 8.2.6. (verified as of 2026-10-15) Sources: https://jira.mongodb.org/browse/SERVER-118428 [source]
