Rio build 884
Rio build 884 (version 8127.18.884) was released on November 10, 2026, on Chromium 158.0.8127.18. These are its release notes from GitHub, where the download and the update feed live.
First release. Download Rio.dmg, drag Rio to Applications, then open it once and allow it in System Settings → Privacy & Security → Open Anyway. Rio updates itself from here on.
Since build 1446, Rio is signed with a Developer ID and notarized by Apple, so a fresh download opens without these steps.
