parseplatform parse-server UPGRADE

Affected: < 8.6.60 · >= 9.0.0 and < 9.6.0 · 9.6.0 alpha1 · 9.6.0 alpha10 · 9.6.0 alpha11 · 9.6.0 alpha12 · 9.6.0 alpha13 · 9.6.0 alpha14

Fixed in: 8.6.60, 9.6.0

Safe to downgrade to: a release before 9.0.0

1. Check installed version

npm ls parse-server

2. UPGRADE to 8.6.60

npm install parse-server@">=8.6.60"

3. If no update is available yet, DOWNGRADE to a release before 9.0.0

npm view parse-server versions npm install parse-server@"<9.0.0"

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.
