We're back! Signal rolled out a protocol change to be post-quantum resilient! Someone was caught intercepting Jabber TLS via certificate transparency! Was the same-origin policy in web browers just a dirty hack all along? Plus secure message format formalisms, and even more beating of the dead horse that is E2EE in the browser.
