Officially HTTP/3 is already released since 2022, but Nginx still didn't created a stable release with HTTP/3 and QUIC support.

However... I'm now using the so called mainline Nginx repository to get the latest Nginx version. Which I use on all my domains as my primary reverse proxy software. I enabled HTTP/3 and QUIC now on all my domains, incl. kbin.melroy.org.

What is HTTP/3 and QUIC???

That is a great question! Currently if you browse a site with HTTPS (TLS) enabled, like basically every website nowadays... The browser starts with TCP connection towards the server, then back a response, then a whole TLS sequence back and forward again between you and the server.. And finally the actual data you want to request and receive..

Both HTTP/3 and QUIC technologies combined will all change this within just 2 requests total instead of 4 requests. Also QUIC will use UDP instead of TCP. See the attachment. I won't go into more details.

TLDR; Browsing the encrypted web just has become faster again.
