The latest released PDF will always be available here . This repository will be updated as we implement and iterate on our cryptographic protocols. See the changelog for a summary of what changed in each version. Note that, before version 4.0, this document was titled "E2E Encryption for Zoom Meetings", but we updated the name to reflect its expanded scope. We still value feedback, recommendation and corrections. Please continue to post them under Issues .
