This was a huge effort involving many people. It started in 2021 when I prototyped DataTree on a long Amtrak journey, and was only pushed over the finish line with generous help from people at @NASAEarthData GESDIS. If there's a feature you want to see in xarray then hit us up!

ALSO this release is the first to be compatible with the much anticipated v3 implementation of zarr-python! (still on its beta branch right now) This brings big performance benefits when reading @zarr_dev on S3 via async and (b) compatibility with @EarthmoverHQ 's Icechunk.

All these integrations represent literally years-worth of effort, all coming out at once 🤯 And that's not even mentioning all the other changes you see in a typical xarray release!
