I think these updates for the 3.0 release are complete now, with the exception of the release notes.

Thanks for looking this over, @ischoegl. I was leaving this in "draft" mode until we merge Cantera/cantera#1599 and tag the release, mainly to make sure that we don't merge it before then. All of the content is "ready for review", though the contents of the release notes especially are subject to change until then. Final updates to the date, PR list, and contributor list in the release notes are all already on my radar, but I'm glad someone else is keeping an eye on these things :eyes:.
