Hello,
Just get an email from Cloudflare, saying they will enable HTTP/3 in the upcoming month.
I don't really mind, because I use CF only for DNS, but that's interesting to see CF adopting HTTP/3.
Firefox / Chrome support HTTP/3, but the option is disabled by default, Safari is about to enable it in the next update.
I've been playing with HTTP/3 since some months, and it's nice to see it going public. (in spite of the fact, it's still a draft).
