call project call UPGRADE

Affected: >= 2.0.1 and <= 3.0.1

Fixed in: newer than 3.0.1

Safe to downgrade to: a release before 2.0.1

1. Check installed version

npm ls call

2. UPGRADE to newer than 3.0.1

npm install call@">3.0.1"

3. If no update is available yet, DOWNGRADE to a release before 2.0.1

npm view call versions npm install call@"<2.0.1"

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.
