#7373 should take care of the date_range errors and #7266 (comment) is my thinking on how to address the base deprecation. I'll have to look into what's causing the other datetime-related errors.

Apologies I haven't much time to work on these issues lately. Hopefully some time should free up for me towards the end of next week.

[spencerkclark]

After a git bisect I traced the units encoding errors to pandas-dev/pandas#49737. I made a PR to address this in xarray (#7441), but it turns out this change may be reverted in pandas (pandas-dev/pandas#50704) so I would hold off on reviewing it until a decision is made there.

[keewis]

the currently failing pint tests are an upstream issues (numpy dev has changed amin and amax to become aliases of min and max instead of the other way around, and round_ has been deprecated in favor of round) and will be fixed by hgrecco/pint#1721

[keewis]

there's also a few failing zarr v3 tests (cc @jhamman):

xarray/tests/test_backends.py::TestZarrDirectoryStoreV3::test_write_read_select_write: KeyError: 'var1'
xarray/tests/test_backends.py::TestZarrDirectoryStoreV3FromPath::test_write_read_select_write: KeyError: 'var2'

and some unrelated tests that didn't raise errors when we expected them (not sure what causes that, I didn't investigate).

[keewis]

let's close this and have the CI open a new issue for the other failing tests. I will point out, though, that the most recent run appears to have segfaulted.
