dask has now been updated to a pandas 2 compatible version, allowing me
to test its reverse dependencies. This found that intake and
xarray-sentinel are broken by pandas 2, while python-xarray is already
broken for other reasons.
A common source of failures is that pandas.util.testing has been renamed
to pandas.testing. Both names were available in all 1.x versions (and
hence in Debian stable and oldstable), so Debian packages that were
using this can immediately switch unconditionally.
pandas 2.1 is likely to be released soon. If this happens before we are
ready to move 2.x to unstable, I plan to go to 2.1 in one transition.
