Hi!

I forked this repo to get a working image of curl with HTTP/3 support so that I could set up an HTTP/3 Kathara laboratory for our Network Fundamentals University course:

https://github.com/redesunlu/curl-container-http3

Although I only did the changes needed to get a debian-dev curl working image, you could merge most of those changes in a new branch here as a starting point. I could add some help to see this implemented upstream (given enough of my spare time).

Regards

any updates?

yes, we want to do - wanted the openssl vs gnutls debate to calm down first
