- Issues
- Fix multi-command mutations of a `DEFAULT` column the part does not store
- Add `EXECUTE AS user SETTINGS name = value` for settings the user declares `CONST` without a value
- Fix(DateTime): Reject out-of-range parseDateTime results
- Count large parts in parallel slices in the trivial count from the text index
- Lightweight `UPDATE` on a partitioned `ReplicatedMergeTree` skips rows that the replica fetches during the `update_sequential_consistency` wait: the partition-pruning analysis caches the parts snapshot before the wait (regression of #110968)
- Fix rows added by WITH FILL when a pass rewrites a selected expression or its sort key, and `uniq` to `count` over non-distinct subqueries
- Fix issue with the write to Iceberg via the glue catalog
- Lazy materialization nondeterministic defaults
- perf(promql): Defer the metric-name drop to the consumer of the vector.
- Cache the dynamic paths mapping in `ColumnObject::insertFrom` to speed up merges of `JSON` columns
