capsule8 capsule8 UPGRADE

Affected: >= 4.6.0 and < 4.10.0

Fixed in: 4.10.0

Safe to downgrade to: a release before 4.6.0

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.
