Safe to downgrade to: a release before 3.0.0

1. Check installed version

npm ls minimatch

2. UPGRADE to 3.1.3

npm install minimatch@">=3.1.3"

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

npm view minimatch versions npm install minimatch@"<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.
