The latest released PDF will always be [available\nhere](https://github.com/zoom/zoom-e2e-whitepaper/blob/master/zoom_e2e.pdf). This repository will be\nupdated as we implement and iterate on our cryptographic protocols.\n\nSee the [changelog](./CHANGELOG.md) for a summary of what changed in each version. Note that, before\nversion 4.0, this document was titled \"E2E Encryption for Zoom Meetings\", but we updated the name to\nreflect its expanded scope. We still value feedback, recommendation and corrections.
