titanhq spamtitan UPGRADE

Affected: >= 7.00 and <= 7.03

Fixed in: newer than 7.03

Safe to downgrade to: a release before 7.00

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

dnf --showduplicates list spamtitan sudo dnf downgrade spamtitan-<VERSION_BEFORE_7.00> sudo dnf versionlock add spamtitan

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.
