Release notes

# Standards compliance tracking & fixes
We are now part of the excellent Http11Probe (https://http-probe.com) tracking RFC9112, 9110 compliance of various servers.

## We are 90th percentile
Even though we've been fully standards compliant when it comes to WebSockets for the last decade, this release fixes some compliance shortcomings when it comes to HTTP. This gets us a score of 153/159 which is more compliant than:
* Deno
* Node
* Bun
* HaProxy
* Caddy
* Spring Boot
* Apache
* NGINX
* Lighttpd
* Tomcat
* H2O

Of course, we are also faster than all of the above.
