v0.22.0

Important

This package is now in maintenance mode, meaning that important bugs will be fixed if possible but we won't
add new features in the next few weeks / months.

The focus of future development is on a completely rewritten version (neopolars) that currently exists in the next branch.
The package in that branch will become the new polars package once the rewrite is complete.

Please check the GitHub issue #1152.

Breaking changes

• Updated Rust Polars to 0.45.1 (#1302).
  • The ddof argument of pl$corr() is removed.
