I'll add more details once I get a chance to look into this more. In the meantime, I'll raise a brief PR to keep polars <= 1.6

Is the issue here that patito's functionality is broken with polars 1.7.0 or just the test suite?

Asking because when installing from main the polars downgrade from 1.9.0 to 1.6.0 was quite large.

The biggest problems will hopefully be fixed when polars releases a new minor/patch version (they had a regression), and then we can clean up the rest of the errors. I'd expect a new release within a few days according to their historic schedule.

See the comments in pola-rs/polars#19277.

Fixed now!

Ah greatly appreciated and sorry to bug the team for another patito release, but would love my project to be on the latest polars (to fix other polars issues I'm hitting).

[thomasaarholt]

New release out now!
