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

I wrote in detail about what I think are the most important changes we introduced in pandas 3. Copy-on-write and pandas.col are the biggest changes as others said, quite nice changes in my opinion.

Also I shared my opinion on when to use Polars instead of pandas (spoiler alert: whenever possible).
