• Release 0.11.2
• Sort broken for polars https://github.com/paddymul/buckaroo/issues/410
• Polars doesn't display row indexes properly for PolarsBuckarooInfiniteWidget https://github.com/paddymul/buckaroo/issues/408
• Buckaroo isn't the default display method for Polars in Marimo https://github.com/paddymul/buckaroo/issues/409

• Release 0.11.1
• Fixes sort for pandas with new column naming
• Fixes lowcode UI with new column naming
