Summary
This release focuses on performance improvements, notably avoiding alloc_zeroed in decompression, and introduces several new features including SQL support for array checks and DataFrame initialization from torch Tensors. Several bugs related to joins, parquet reading, and date/datetime conversions have also been fixed.
✨ New Features
- Highlight nodes in streaming phys plan graph.
- Show physical stage graph.
- Add structure for dispatching iceberg to native scans.
- Add SQL support for checking array values with `IN` and `NOT IN` expressions.
- Support `DataFrame` and `Series` init from torch `Tensor` objects.
- Add `RoundMode` for Decimal and Float.
🐛 Bug Fixes
- Fix streaming outer join coalesce bug.
- Remove redundant print statement in `assert_frame_schema_equal()`.
- Fix bug in `.unique()` followed by `.slice()`.
- Fix error reading parquet with datetimes written by pandas.
- Fix `schema_overrides` not taking effect in ND
- Fold flags and verify scalar correctness in apply.
- Invalid values were triggering panics instead of returning ``null`` in `dt.to_date` / `dt.to_datetime`.
- Ensure numpy `isinstance` check is lazy (avoid forcing the dependency).
- Fix incorrectly dropped sort after unique for some queries.
- Fix incorrect ternary agg state with mixed columns and scalars.
- Make `replace` and `replace_strict` properly elementwise.
- Fix index out of bounds panic on parquet prefiltering.
- Fix integer underflow when checking parquet UTF-8.
- Add implementation for `array.get` with idx overflow.
