- Issues
- SQL: unknown or alias-hidden names are accepted in correlated subquery
- fix: Preserve fractional seconds in hive partition paths for `Time` keys
- `DataFrame.join` on a sorted float key drops NaN matches (sorted-merge fast path compares with IEEE `==`)
- `scan_delta`: table opened several times when a scan is reused across plan branches (regression in 1.43)
- Partitioned write puts a NULL key and the string "__HIVE_DEFAULT_PARTITION__" into the same file: rows silently lost, file sometimes unreadable
- Allow explicit pruning of unused inputs in lazy horizontal concatenation
- INT96 timestamps inside a Map saturate although the schema requests Datetime("us")
- NDJSON reader panics on Int8/Int16/UInt8/UInt16/Time/Duration schema types
- perf: Compute group-by keys that are derived from other keys after the aggregation
- fix: Validate input dtype of `str`, `dt`, `bin` and `cat` namespace functions during schema resolution
