fireblink object-collider UPGRADE

Affected: >= 1.0.0 and <= 1.0.3

Fixed in: newer than 1.0.3

Safe to downgrade to: a release before 1.0.0

1. Check installed version

npm ls object-collider

2. UPGRADE to newer than 1.0.3

npm install object-collider@">1.0.3"

3. If no update is available yet, DOWNGRADE to a release before 1.0.0

npm view object-collider versions npm install object-collider@"<1.0.0"

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.
