Brave 1.97.59: Chromium 155.0.8059.85 security bump

If Brave is the browser you actually use at home, the 1.97.57 bump is not the finish line anymore. On October 16, 2026, Brave shipped Release Channel 1.97.59, which upgrades Chromium to 155.0.8059.85.

That Chromium line matches the security package Google put into Chrome Stable 155.0.8059.84/.85 on October 15 (our Chrome note). Brave’s earlier 1.97.57 Release landed on Chromium 155.0.8059.80. Updating Chrome does not update Brave. Updating Brave does not update Chrome.

What Brave published

Brave’s desktop changelog for 1.97.59 and the matching GitHub release v1.97.59 list one desktop change that matters for this note:

• Upgraded Chromium to 155.0.8059.85 (issue #59971)

The same GitHub release notes also list an Android Chromium bump to 155.0.8059.85. Phone and desktop still update through separate stores and installers.

As of October 20, Brave’s latest notes page still lists 1.97.57 as the newest release, so it lags GitHub. Treat brave://version and the About Brave page as the source of truth for the build on your machine. In a Brave Community thread, Windows and Linux users report already running 1.97.59.

For a home security checklist, the Chromium line is the reason to install today. Chromium 155.0.8059.85 is the build Google shipped on October 15 with 10 security fixes, including a Critical one, so this is how that fix set reaches Brave.

Why 1.97.57 is not enough anymore

If brave://version shows Brave 1.97.57 with Chromium 155.0.8059.80, you did the right thing after October 14. You still need 1.97.59 (or newer) for Chromium 155.0.8059.85.

Same habit every time:

1. Update
2. Fully quit and relaunch
3. Prove it with brave://version

Downloaded is not running. Read both the Brave version and the Chromium version on that page.

How to update and verify on a home PC or Mac

1. Open Brave on the computer you browse on.
2. Check for updates:
   • Windows / Linux: Menu (three lines) → About Brave.
   • Mac: Brave menu → About Brave.
3. Stay on that page until Brave finishes downloading and offers a relaunch, or until it already shows 1.97.59.
4. Relaunch when prompted. Do not click Later and leave old windows open for hours.
5. If the version still looks old, fully quit Brave (every window), then open it again.
6. Type brave://version in the address bar. Confirm:
   • Brave version 1.97.59 (or a newer Release build if Brave already moved past it)
   • Chromium 155.0.8059.85 (or a later 155.0.8059.x if Brave ships another bump)
7. Repeat on any other home PC that still has Brave installed, including the laptop that sleeps with Brave still open.

If About Brave says an update is coming but does not offer 1.97.59 yet, give Release a day, then check again. Staged rollouts are normal.

Android and iOS Brave are separate

Desktop Release notes are for the computer browser. Phone browsers update through Google Play or the App Store on their own schedule. A desktop Brave update does not patch Brave on your phone. If you browse in Brave on Android, open the store listing after this Chromium bump, update, then open the app once so the new build actually launches. iOS follows the App Store separately.

Do this / don’t do that

Do

• Force About Brave, relaunch, and confirm brave://version shows 1.97.59 with Chromium 155.0.8059.85.
• Treat the Chromium .85 bump as “install today,” not “install when I remember on Sunday.”
• Keep Chrome, Edge, Firefox, and Brave on their own update habits if you use more than one browser at home.

Don’t

• Do not stop at Brave 1.97.57 because you “already updated after Chrome 155.” That build was still Chromium 155.0.8059.80.
• Do not leave old Brave windows running after an update prompt.
• Do not skip the Chromium line on brave://version. The Brave version and the Chromium version are both worth reading.
• Do not wait for exploit writeups. Brave’s notes do not list individual Chromium bugs, and patching is still the job.

Bottom line

Brave 1.97.59 hit the desktop Release channel on October 16, 2026 and upgrades Chromium to 155.0.8059.85 (desktop changelog, GitHub release). That is Brave’s way of carrying Chrome’s October 15 155.0.8059.84/.85 security set into the browser you actually launch. On your own computer: update, fully quit and relaunch, confirm brave://version. That is the whole job.
