C2PA Technical Specification 2.2 was published in May 2025, adding features including soft-binding manifest recovery, multipart assets, updated timestamp/revocation handling and a dedicated claim-signing extended key usage.
What this does not establish
C2PA provenance is not truth, copyright ownership, authenticity of depicted events or proof that a signer is honest.
Counterevidence & uncertainty
Trust depends on signer validation, trust lists, asset binding, manifest retention and implementation security.
What would change the reading
Track versions 2.3+, trust-list policy, security advisories and cross-platform preservation tests.
