Yup, we haven't turned it on by default yet - but this no longer really due to bugs, but missing UX features. The stuff that remains is: * Cross-signing devices when you sign up to remove verification pain * Ability to access history from before the point you join the room (if desired) * Better UX for verification (comparing mnemonic phrases rather than public key fingerprints) * Ability to optionally back up E2E keys, encrypted, on the server so you don't lose your history if you lose all your devices * Ability to search E2E rooms (using a clientside search engine) * ...and fixing any last key management bugs, although right now we believe we've fixed almost all of them.
