That's not how I interpret the link given by @dcherian, which states ""rolling"" minimum versions based on age.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1550109629

I assume you have given this a lot of thought, but imho the minimum dependency versions should be decided according to features needed, not timing.

> For your current issue, I'm surprised this patch didn't fix it: [conda-forge/conda-forge-repodata-patches-feedstock#429](https://github.com/conda-forge/conda-forge-repodata-patches-feedstock/pull/429)

Thanks for the pointer.
I am not sure why, maybe I was updating too eagerly before the feedstock was fixed, but `mamba update --all` on py38 pulled pandas 2.0 without updating xarray.

`python3.8 -m pip install xarray` will  result in incompatible versions.

Just to let you know that this change breaks python 3.8 setups with automatic updates becuase the `pandas` version is not restricted, so it will be happily updated to version 2 or higher. Which in turn is not compatible with xarray < 2023.2, which cannot be installed on python 3.8 because of this change.
Don't know why the min python version was changed, this PR doesn't say why it was necessary.
