08/14/2026, 3:05 PMx.1 release, it’s a big one. The most important user-visible changes are:
• Proof of possession is now optional.
• The verifier can now request arbitrary attributes to be attested by the client.
The biggest changes under the hood are all about security hardening. We’ve tested our home-grown attestation parser against thousands of real Android devices across a wide range of makes and models, and it’s looking remarkably robust—arguably more so than anything Google has put out.
Cheers!
