CRITICAL UPDATE: UPGRADE TO ≥3.104.2 ASAP

</aside>

3.110.0 / 04.11.2026

• Database migration: adds a nullable column document_versions.stateVector
• performance improvements
• feat: a SLOW … warning is now also logged when applying an update or converting a document to JSON blocks the event loop for more than SLOW_SYNC_THRESHOLD_MS (default 300). Expect more of these warnings, and more debug-level timing lines, on installs with large documents.
• fix: user.disconnected reported numConnectedUsers: 1 when the last user left (since 3.107.0). It reports 0 again, and a leave processed after the connection closed is no longer reported twice.
• fix: DELETE /api/documents/:identifier right after the last user left no longer waits for the 5s unload grace period in cluster mode.

3.109.0 / 02.11.2026

• feat: document.saved and content.changed webhooks include checksums per fragment, usable as checksum in PATCH /api/documents/:identifier
• feat: POST /api/admin/stateless sends a stateless message to all open documents
• fix: document checksums no longer depend on attribute order. Checksum values change, but PATCH still accepts old ones
• fix: concurrent creates of the same document return 409 instead of overwriting it
