Vendor recommendation

The vendor's own statement about what to run, with its date and source. Separate from vulnerabilities and from support status: being behind a recommendation is not a vulnerability, and a supported release is not necessarily the recommended one.

Cisco publishes no recommended-release page Patcharo can read. The fixed releases on this site come from the security advisories only; nothing is inferred from version numbers.

Support status

From the vendor's published life-cycle policy; support is not a recommendation.

How Patcharo reads this

Affected and fixed releases come from the vendor's structured statements, matched by exact version and patch level. The recommendation is the vendor's own statement; the support status comes from its life-cycle policy. Unknown never becomes Not affected.
