Affected: 7.x-1.0 · 7.x-1.1 · 7.x-1.2 · 7.x-1.x-dev

Fixed in: no fixed release known

Safe to downgrade to: a release before 7.x-1.0

2. No fixed release: DOWNGRADE to a release before 7.x-1.0 (Debian / Ubuntu)

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
