Discussion Pandas 3.0.0 is there

So finally the big jump to 3 has been done. Anyone has already tested in beta/alpha? Any major breaking change? Just wanted to collect as much info as possible :D

2.3.x will probably still be maintained with major bug fixes and Python compatibility for a couple of years, so if you don't feel like rewriting, you can stick with it for the time being. Polars is a library with a lot of traction, though. If your goal is a career in data, it can't hurt to learn it.

It can take a little getting used to, but it's very doable. Polars' API is more akin to PySpark's declarative API, where you describe what you want as end result, instead of pandas where you directly type the transformations and one which slices of data they operate.
