Ecosystem updates
Public release notes are grouped by product.
Follow changes
Each app has its own release cycle. This site shows notes approved for publication by their owners; preview images do not replace release notes.
What an update tells you
An update identifies the product, release or date, useful changes and any action users need to take. Experimental items keep their stated stage. An interface image or reachable domain does not establish that every feature is available.
Check your version
An announcement may apply to one product or a specific set of releases. Check its product page and guide for update steps, information to preserve and changes affecting your work.
