| 4 minute read
Polars py-1.42.0 was published on June 24, 2026, as the Python Polars 1.42.0 release. The main user visible work is a mix of cloud IO control, early out of core spilling, SQL fixes, and query optimizer correctness. The release is not marked as a prerelease, so teams using Python Polars should treat it as the current stable release train and read the migration notes before upgrading.
