Changelog

TODO: user-facing release notes. Reverse-chronological. Include version, date, headline change, and a 2-line description per release. Link to the security advisory page if a release contains a security fix.

Owner: @andy. Cross-reference: the Sparkle appcast (CM050) – the appcast XML is the source of truth, this page is the human-readable mirror. Companion app changelog comes from App Store Connect and gets mirrored here too.
