Titan M implementation of StrongBox Keymaster was updated to support Keymaster v4.1 and attestation v4. Finer-grained boot and vendor patch level reporting is an added feature: twitter.com/GrapheneOS/sta Traditional TEE-based Keymaster is still Keymaster v4 and attestation v3.

The documentation at developer.android.com/training/artic and source.android.com/security/keyst hasn't yet been updated to list the new features. Noticed we needed to add support for this as part of implementing Pixel 4a (5G) and Pixel 5 support but it applies to the older devices with a Titan M too.
