We've now got available the release candidate for pandas 2.0, where you can already test the next major version of pandas.
In particular, if you have pandas code in production, we recommend testing it with the release candidate, and report any bug to us, so we can fix it before the final release. Note that you should address any FutureWarning in pandas 1.5.3 before you upgrade to pandas 2, otherwise your code will break.
