vercel next.js UPGRADE

Affected: >= 16.3.0 and < 16.3.8

Fixed in: 16.3.8

Safe to downgrade to: a release before 16.3.0

1. Check installed version

npm ls next.js

2. UPGRADE to 16.3.8

npm install next.js@">=16.3.8"

3. If no update is available yet, DOWNGRADE to a release before 16.3.0

npm view next.js versions npm install next.js@"<16.3.0"

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.
