HTTP/2 and its header compression algorithm HPACK implementation.
The framing layer of HTTP/2 is implemented as a reusable library.
Also included are an HTTP/2 client, server, proxy, load test and
benchmarking tool.

NOTE

Support for previously deprecated Python bindings, modules,
and documentation was dropped some releases ago.


2024-03-01	1.60.0

The following dependencies have been updated:

ngtcp2
nghttp3

- CUnit has been replaced with ngtcp2/munit.
- munit is pulled via git submodule.
- The flags to build applications with libbrotli have been added.

h2load

- --sni option has been added.

src

- certificate compression support with boringssl (or aws-lc) and
  libbrotli has been added.

third-party

- llhttp has been updated.
- mruby is updated to v3.3.0.

build

- cmake build and install trees are now fixed.

lib

- RFC 7540 priorities (aka stream dependencies) APIs have been deprecated.
  They work just like before, but in the future release after the end of
  2024, the functionality is removed, and the deprecated APIs start
  behaving differently.
  See the API documentation for details.
  RFC 7540 priorities have been deprecated by RFC 9113.
  Consider migrating RFC 9218 extensible prioritization scheme.

- The APIs that use ssize_t, including structs and callback functions,
  have been deprecated.
  New APIs that use nghttp2_ssize are introduced as a replacement.
  The usage of ssize_t is problematic for several reasons.
  Some platforms do not define ssize_t.
  The minimum value of ssize_t that POSIX requires is -1 which makes
  nghttp2 error code out of range.
  nghttp2_ssize is an alias of ptrdiff_t that is in C standard and covers
  our error code range.

- New code should use new nghttp2_ssize APIs.

- The existing applications should consider migrating to new APIs.

- The deprecated ssize_t APIs continue to work for backward compatibility.

Here is the summary of the deprecated APIs and their replacements:

Callback functions:

nghttp2_data_source_read_callback => nghttp2_data_source_read_callback2
nghttp2_data_source_read_length_callback => nghttp2_data_source_read_length_callback2
nghttp2_pack_extension_callback => nghttp2_pack_extension_callback2
nghttp2_recv_callback => nghttp2_recv_callback2
nghttp2_select_padding_callback => nghttp2_select_padding_callback2
nghttp2_send_callback => nghttp2_send_callback2

Structs:

nghttp2_data_provider => nghttp2_data_provider2

Functions:

nghttp2_hd_deflate_hd => nghttp2_hd_deflate_hd2
nghttp2_hd_deflate_hd_vec => nghttp2_hd_deflate_hd_vec2
nghttp2_hd_inflate_hd2 => nghttp2_hd_inflate_hd3
nghttp2_pack_settings_payload => nghttp2_pack_settings_payload2
nghttp2_session_callbacks_set_data_source_read_length_callback => nghttp2_session_callbacks_set_data_source_read_length_callback2
nghttp2_session_callbacks_set_pack_extension_callback => nghttp2_session_callbacks_set_pack_extension_callback2
nghttp2_session_callbacks_set_recv_callback => nghttp2_session_callbacks_set_recv_callback2
nghttp2_session_callbacks_set_select_padding_callback => nghttp2_session_callbacks_set_select_padding_callback2
nghttp2_session_callbacks_set_send_callback => nghttp2_session_callbacks_set_send_callback2
nghttp2_session_mem_recv => nghttp2_session_mem_recv2
nghttp2_session_mem_send => nghttp2_session_mem_send2
nghttp2_submit_data => nghttp2_submit_data2
nghttp2_submit_request => nghttp2_submit_request2
nghttp2_submit_response => nghttp2_submit_response2
For those applications that do not want to see ssize_t in nghttp2.h header file at all, define NGHTTP2_NO_SSIZE_T macro before including nghttp2.h. It hides all ssize_t APIs.
