DOC: 1.0.4 whatsnew
Brings 1.0.4.rst to master & sets the release date (for tomorrow)

cc @simonjayhawkins.
just updated 1.0.4 release notes on 1.0.4. was planning this next. I've set the release date to today. was planning to tag (locally) now and hopefully if conda and pip tests pass (they did on a practice run) tag today. The pdf docs seem problematic though but don't want to hold things up. Ah great. I've restored from 1.0.x, so things should match. Was also planning to remove the notes from 1.1 whatsnew for things backported. will open pr shortly. I think will also need to update 1.0.3 contributors on master. #33970 Thanks. Feel free to push those changes to this branch, or as a followup. Whatever is easiest for you. > Thanks. Feel free to push those changes to this branch, or as a followup.
