• ...

Comments

This will be the first release that drops support for the legacy DataFrame and removes the need for the dask-expr dependency

We will have to release an empty dask-expr package (at least for pypi). If people actually added dask-expr to their requirements/environment they would otherwise never get the newer dask version since the dask-expr package pins hard to the dask version

dask/dask#11666 if possible
