openclaw openclaw UPGRADE

Affected: >= 2026.2.23 and < 2026.4.12

Fixed in: 2026.4.12

Safe to downgrade to: a release before 2026.2.23

1. Check installed version

npm ls openclaw

2. UPGRADE to 2026.4.12

npm install openclaw@">=2026.4.12"

3. If no update is available yet, DOWNGRADE to a release before 2026.2.23

npm view openclaw versions npm install openclaw@"<2026.2.23"

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
