Release date: July 16, 2026
MatrixOne version: v4.1.1

MatrixOne 4.1.1 is a stability patch release on top of 4.1.0. It hardens logtail reads against pending table apply, backports fenced orphan unlock in lockservice, and fixes issues across planner index pushdown, publication lookup, data branch BLOB merge, uint64 division, Parquet/Hive external tables, and default incremental checkpoint interval.

Key Improvements

Storage & Checkpoint

• Incremental Checkpoint: Set the default incremental checkpoint interval to 5m

External Tables & Data Loading

• Parquet: Support Parquet cross-type conversions for broader schema compatibility
• Data Branch: Support BLOB columns in data branch merge

Key Bug Fixes

Transaction, Logtail & Lock Service

• Logtail Reads: Fence latest logtail reads with pending table apply to avoid inconsistent reads during apply
• Lock Service: Backport fenced orphan unlock to 4.1-dev to prevent unsafe unlock of orphaned locks

SQL Correctness & Planner

• Index Pushdown: Guard regular index ordered LIMIT pushdown to avoid incorrect results
• Numeric Division: Fix uint64 division correctness
• Publication: Fix publication table lookup for quoted database names

External Tables, Hive & Test Stability

• Hive Partition Cache: Close partition cache singleflight race
• Backup / Checkpoint Tests: Stabilize backup checkpoint timeout in TAE tests
