Support status

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

The life-cycle policy Patcharo reads states nothing about this branch.

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.

Recommended release per model

The vendor states one recommended release per hardware model (9 models); models are grouped by recommended release.
