HTTP/2 C library and tools

Nghttp2 v1.53.0

We have released nghttp2 v1.53.0.


libnghttp2 uses ngtcp2/sfparse to parse Structured Field Values.


The following dependencies have been updated:

  • ngtcp2
  • nghttp3
  • OpenSSL(quictls)
  • BoringSSL


Bumped mruby to 3.2.0.


nghttpx now sends NEW_TOKEN on path change.

This release fixes numeric hostname verification in peer certificate.

When quitting, nghttpx now waits for all worker processes to stop. Previously, we just exit the event loop when the last process exits. But the because of the bug, it does not work as intended.

nghttpx logs a correct PID on fork.

nghttpx now waits for new worker process to be ready before sending graceful shutdown event to the existing worker processes to avoid down time during configuration reload.

Fixes the bug that causes 400 response after HTTP upgrade failure.
