Re: C2PA reading materials

Wanted to let everyone know that we have published our new 2.2 version of the C2PA Specification for Content Credentials.   It can be found at the usual spot - https://c2pa.org/specifications/ with a version history at https://c2pa.org/specifications/specifications/2.2/specs/C2PA_Specification.html#_version_history


However, I very much want to point out our completely revamped Explainer documentation at https://c2pa.org/specifications/specifications/2.2/explainer/Explainer.html based on many of the comments and feedback we’ve heard from this and others communities recently.

Looking forward to talking to folks tomorrow…
