I'm no expert on TLS 1.3, but I thought that other folks on Wikitech-l might be interested in the industry news about the subject. The relevant WMF Phabricator task is https://phabricator.wikimedia.org/T170567.
Articles:
* "An Overview of TLS 1.3 – Faster and More Secure": https://kinsta.com/blog/tls-1-3/
* "Why TLS 1.3 isn't in browsers yet": https://blog.cloudflare.com/why-tls-1-3-isnt-in-browsers-yet/
* "Big banks want to weaken the internet’s underlying security protocol": https://www.cyberscoop.com/tls-1-3-weakness-financial-industry-ietf/. WMF employees who do advocacy work might be interested in this article, which is why I'm sending this email to WMF Legal.
