v1.48.0		Jun 24th, 2022

lib

* This release adds RFC9218 Extensible Prioritization Scheme for HTTP.
  It is enabled by submitting NGHTTP2_SETTINGS_NO_RFC7540_PRIORITIES via
  nghttp2_submit_settings(). See Stream priorities section of
  Programmers’ Guide.

* It fixes the stream stall bug when the initial window size is decreased.

build

* Now applications can be built with Libressl 3.5.

* If --enable-lib-only configure option is used, no application
  libraries are checked.

src

* The default TLS cipher suites are updated.


* ktls support has been added to nghttp, nghttpd, nghttpx, and h2load if
  they are built with OpenSSL >= 3.0.0.

nghttpd

* This release fixes the bug that stalls TLS read operation.

nghttpx

* nghttpx by default disables RFC 7540 tree based HTTP/2 priorities and
  uses RFC 9218 priorities instead. It has a fallback mechanism to RFC
  7540 if client does not send SETTINGS_NO_RFC7540_PRIORITIES.

* affinity-cookie-stickiness backend parameter has been added.

* The session affinity feature which had been broken for quite some time
  has been fixed.

third-party

* llhttp has been updated to the latest version.

* mruby has been updated to 3.1.0.

* neverbleed has been updated the latest version with some amends.
