Thanks. Does the original whatsnew from the other PR describe this change as well? > Thanks. Does the original whatsnew from the other PR describe this change as well?

I think so yes, it's still in general about preserving EA dtype in concat. But I added the issue number to the exsting whatsnew. Merged master.

@jreback was the discussion in https://github.com/pandas-dev/pandas/pull/34985#discussion_r449643794 resolved? yes this is fine to merge
