A great release. But one other great improvement was not mentioned in the release notes: The states tab in the Developer tools is now lightning fast. If you had lots of entities, previously you had to wait a long time for the tab to load. Now it is there instantly. A big thanks to whomever made this change!
Personally I also love the changes to the automation editor, and the new way to control the entity id for template sensors. But this release is so jam packed, there is lots to love.
