This is a patch release for the v1.4 LTS line. See DuckDB's changelog for all changes in DuckDB.
What's changed in DuckDB-Python
- Fix a memory leak on every Python scalar UDF call.
- Fix data corruption when reading from fsspec filesystems concurrently (seek+read/write are now atomic).
- Fix incorrect results from Arrow/PyArrow filter pushdown when an OR predicate contains a dynamic filter (e.g.
ORDER BY ... NULLS FIRST LIMIT n), reported in issue #460. - Raise a clear error instead of segfaulting when None is passed to
Relation.join.
