Rio build 1055
Rio build 1055 (version 8127.18.1055) 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.
Update for the beta.
- Onboarding asks once to bring your Arc setup over.
- Pick a look: the theme colors work.
- Reinstall on an imported extension opens Chrome's install prompt.
- The Library's Spaces view shows every space side by side.
- Fixed a crash during import (Replace while Settings was open).
- Hovering the left edge brings the hidden sidebar out sooner.
- Rename in the bottom-left pop-up renames the file you picked.
- Rio now checks for updates every hour, and a card at the bottom of the sidebar offers each new version: restart now, or it installs when you quit.
First install: download Rio.dmg, drag Rio to Applications, open it once, then allow it in System Settings, Privacy & Security, Open Anyway.
Since build 1446, Rio is signed with a Developer ID and notarized by Apple, so a fresh download opens without these steps.
