fault in a worker process (for SSL proxying) might occur if AIO was
used in a subrequest.
*) Bugfix: a segmentation fault might occur in a worker process if SSL
proxying was used along with the "image_filter" directive and errors

reason phrase was handled incorrectly.

library.
Thanks to ZhenZhong Wu.

Changes with nginx 1.25.2 15 Aug 2023
*) Feature: path MTU discovery when using HTTP/3.
*) Feature: TLS_AES_128_CCM_SHA256 cipher suite support when using
HTTP/3.
*) Change: now nginx uses appname "nginx" when loading OpenSSL
configuration.

--with-openssl option was used to built OpenSSL and the OPENSSL_CONF
environment variable is not set.
*) Bugfix: in the $body_bytes_sent variable when using HTTP/3.
*) Bugfix: in HTTP/3.

Changes with nginx 1.25.1 13 Jun 2023
*) Feature: the "http2" directive, which enables HTTP/2 on a per-server
basis; the "http2" parameter of the "listen" directive is now
deprecated.
*) Change: HTTP/2 server push support has been removed.
*) Change: the deprecated "ssl" directive is not supported anymore.
*) Bugfix: in HTTP/3 when using OpenSSL.

Changes with nginx 1.25.0 23 May 2023
*) Feature: experimental HTTP/3 support.

Changes with nginx 1.23.4 28 Mar 2023
*) Change: now TLSv1.3 protocol is enabled by default.
*) Change: now nginx issues a warning if protocol parameters of a
listening socket are redefined.
*) Change: now nginx closes connections with lingering if pipelining was
used by the client.
*) Feature: byte ranges support in the ngx_http_gzip_static_module.
*) Bugfix: port ranges in the "listen" directive did not work; the bug
had appeared in 1.23.3.
Thanks to Valentin Bartenev.
*) Bugfix: incorrect location might be chosen to process a request if a
prefix location longer than 255 characters was used in the
configuration.
*) Bugfix: non-ASCII characters in file names on Windows were not
supported by the ngx_http_autoindex_module, the ngx_http_dav_module,
and the "include" directive.
*) Change: the logging level of the "data length too long", "length too
short", "bad legacy version", "no shared signature algorithms", "bad
digest length", "missing sigalgs extension", "encrypted length too

Changes with nginx 1.23.3 13 Dec 2022
*) Bugfix: an error might occur when reading PROXY protocol version 2
header with large number of TLVs.
*) Bugfix: a segmentation fault might occur in a worker process if SSI
was used to process subrequests created by other modules.
Thanks to Ciel Zhao.
*) Workaround: when a hostname used in the "listen" directive resolves
to multiple addresses, nginx now ignores duplicates within these
addresses.
*) Bugfix: nginx might hog CPU during unbuffered proxying if SSL
connections to backends were used.

Changes with nginx 1.23.2 19 Oct 2022
*) Security: processing of a specially crafted mp4 file by the
ngx_http_mp4_module might cause a worker process crash, worker
process memory disclosure, or might have potential other impact
(CVE-2022-41741, CVE-2022-41742).
*) Feature: the "$proxy_protocol_tlv_..." variables.
*) Feature: TLS session tickets encryption keys are now automatically
rotated when using shared memory in the "ssl_session_cache"
directive.

Thanks to Murilo Andrade.
*) Change: now when using shared memory in the "ssl_session_cache"
directive the "could not allocate new session" errors are logged at
the "warn" level instead of "alert" and not more often than once per

*) Bugfix: in logging of the PROXY protocol errors.
Thanks to Sergey Brester.

Changes with nginx 1.23.1 19 Jul 2022
*) Feature: memory usage optimization in configurations with SSL
proxying.
*) Feature: looking up of IPv4 addresses while resolving now can be
disabled with the "ipv4=off" parameter of the "resolver" directive.
*) Change: the logging level of the "bad key share", "bad extension",
"bad cipher", and "bad ecpoint" SSL errors has been lowered from
"crit" to "info".
*) Bugfix: while returning byte ranges nginx did not remove the
"Content-Range" header line if it was present in the original backend
response.
*) Bugfix: a proxied response might be truncated during reconfiguration
on Linux; the bug had appeared in 1.17.5.

Changes with nginx 1.23.0 21 Jun 2022
*) Change in internal API: now header lines are represented as linked
lists.
*) Change: now nginx combines arbitrary header lines with identical
names when sending to FastCGI, SCGI, and uwsgi backends, in the
$r->header_in() method of the ngx_http_perl_module, and during lookup
of the "$http_...", "$sent_http_...", "$sent_trailer_...",
"$upstream_http_...", and "$upstream_trailer_..." variables.
*) Bugfix: if there were multiple "Vary" header lines in the backend
response, nginx only used the last of them when caching.
*) Bugfix: if there were multiple "WWW-Authenticate" header lines in the
backend response and errors with code 401 were intercepted or the
"auth_request" directive was used, nginx only sent the first of the
header lines to the client.
*) Change: the logging level of the "application data after close
notify" SSL errors has been lowered from "crit" to "info".
*) Bugfix: connections might hang if nginx was built on Linux 2.6.17 or
newer, but was used on systems without EPOLLRDHUP support, notably
with epoll emulation layers; the bug had appeared in 1.17.5.
