Enhancement: Changed the approach for delimited batch sets. Delimited batch sets now return and accept original rowIDs.

Enhancement: Improved performance of full-text index.

Enhancement: Added support for metadata garbage collection for Azure pipelines.

Enhancement: Improved error handling for regular expressions: errors are now properly raised instead of returning SQL NULL. To avoid breaking existing apps the regexp_error_handling_level engine variable was added. This variable controls the behaviour of error handling for regexp operations.

Enhancement: Added a new engine variable, ssl_ca_for_client_cert, for client certification.

Enhancement: Added knob to disable cardinality estimates on JSON/BSON columns during analyze.

Enhancement: Added the MV_ACTIVE_METADATA_VERSIONS information schema view that provides visbiility into active metadata transaction read versions.

Enhancement: Added the MV_GC_EVENTS information schema view that provides visibility into garbage collection passes. This view is gated behind the preview feature and engine variable enable_gc_events.

Bugfix: Fixed query performance issue caused by heuristic estimate selectivity being overwritten.

Bugfix: Fixed an issue where monitoring pipelines would sometimes fail to produce data for large source clusters.

Bugfix: Fixed row count estimation for union subquery containing Materialized Common Table Expression(MCTE)s.

Bugfix: Updated third party libraries to fix security vulnerabilities.

Bugfix: Bumped the _bt timeout from 60 seconds to 180 seconds.

Bugfix: Fixed incorrect aggregation of leaf query stats in Query_completion tracing.

Bugfix: Fixed an issue where certain commands (e.g. DROP TABLE) could hang due to aborted queries caused by stuck collocated services triggered by external functions.

Bugfix: Resolved an issue where the regular expression engine would return SQL NULL when hitting the memory limit during execution. It now raises an appropriate error instead.

Bugfix: Implemented shallow copy of a table with a dropped index, the shallow copy now includes the in-memory segment.

Enhancement: Enabled synchronous Distributed Plancache lookup during query execution.

Enhancement: Added Lucene logs to the cluster report.

Enhancement: Added statistics related to AWS S3 lookup latency.

Bugfix: Prevented the drop of Distributed Plancache files on regular Persistent Plancache GC.

Bugfix: Fixed a bug in lateral join.

Enhancement: Distributed Plancache pool size adjustment fails gracefully.

Enhancement: Changed the default collation from utf8mb4_general_ci to utf8mb4_bin.

Bugfix: Fixed an issue where periodic autostats was disabled when it should not have been.

Bugfix: Fixed a crash in lockfree hashtable when the engine is under high memory pressure. Reports an "out of memory" error instead.

Bugfix: Fixed an issue in CTE query rewrites caused when a CTE referenced a recursive CTE.

Bugfix: Fixed the predicate pushdown logic for materialized common table expressions.

Enhancement: Added the SEQUENCE modifier for AUTO_INCREMENT. Refer to AUTO_INCREMENT AS SEQUENCE for more information.

Enhancement: Added support for file filtering based on the WHERE clause in the pipeline declaration. For more details, refer to Iceberg Ingest.

Bugfix: Fixed an error named ER_BAD_TABLE_ERROR on UPDATE or DELETE queries with a specific shape.
