Changes with nginx 1.21.4 02 Nov 2021
*) Change: support for NPN instead of ALPN to establish HTTP/2
connections has been removed.
*) Change: now nginx rejects SSL connections if ALPN is used by the
client, but no supported protocols can be negotiated.
*) Change: the default value of the "sendfile_max_chunk" directive was
changed to 2 megabytes.
*) Feature: the "proxy_half_close" directive in the stream module.
*) Feature: the "ssl_alpn" directive in the stream module.
*) Feature: the $ssl_alpn_protocol variable.
*) Feature: support for SSL_sendfile() when using OpenSSL 3.0.
*) Feature: the "mp4_start_key_frame" directive in the
ngx_http_mp4_module.
Thanks to Tracey Jaquith.
*) Bugfix: in the $content_length variable when using chunked transfer
encoding.
*) Bugfix: after receiving a response with incorrect length from a
proxied backend nginx might nevertheless cache the connection.
Thanks to Awdhesh Mathpal.
*) Bugfix: invalid headers from backends were logged at the "info" level
instead of "error"; the bug had appeared in 1.21.1.
*) Bugfix: requests might hang when using HTTP/2 and the "aio_write"
directive.

The older, but still widely deployed PCRE library, originally released in 1997, is at version 8.45. This version of PCRE is now at end of life, and is no longer being actively maintained. Version 8.45 is expected to be the final release of the older PCRE library, and new projects should use PCRE2 instead.
Note that the former ftp.pcre.org FTP site is no longer available. You will need to update any scripts that download PCRE source code to download via HTTPS, Git, or Subversion from the new home on GitHub instead.
