jenzabar jenzabar UPGRADE

Affected: >= 8.2.1 and <= 9.2.0

Fixed in: newer than 9.2.0

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.
