- Issues
- Bound column count in inserted RowBinary header
- Fix wrong results in largestTriangleThreeBuckets for DateTime64 values near the type's upper bound
- Refuse a `Set` table on the right side of `IN` when a row policy applies to it
- Hide secret arguments in `EXPLAIN AST` output
- JIT `bitShiftRight`/`bitShiftLeft` skip the out-of-range shift clamp
- Relaxed `has` rule accepts a `Dynamic` key, so a matching row is pruned
- A rank() <= N filter above a window sorts every row to compute ranks it discards: bounding the window sort per partition is 16% faster on TPC-DS query_67
- Remove bogus assertion from `format_fuzzer`
- Don't share a query-context-dependent serialization through DataTypesCache
- Let `estimateReadRowsCount` keep an index analysis taken before filter pushdown off the read step
