nghttpx

Encrypted Client Hello (ECH) support has been added.

h2load

This release adds --h3 option, which is a short hand of --alpn-list=h3.

It also adds the option to save the measurement result to a file in JSON format, including raw samples. See --output-file option.

TLS resumption support has been added. The new option --tls-session-file specifies the file path that h2load reads and writes TLS session.

The feature to plot histogram has been added. Use --histogram option to enable it.

New metrics have been added: median, p95, p99, and more QUIC specific metrics.

This release fixes the bug that h2load does not stop early with -D option
