node-rules project node-rules UPGRADE

Affected: >= 3.0.0 and < 5.0.0

Fixed in: 5.0.0

Safe to downgrade to: a release before 3.0.0

1. Check installed version

npm ls node-rules

2. UPGRADE to 5.0.0

npm install node-rules@">=5.0.0"

3. If no update is available yet, DOWNGRADE to a release before 3.0.0

npm view node-rules versions npm install node-rules@"<3.0.0"

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.
