Changes with nginx 1.14.2 04 Dec 2018
*) Bugfix: nginx could not be built by gcc 8.1.
*) Bugfix: nginx could not be built on Fedora 28 Linux.
*) Bugfix: in handling of client addresses when using unix domain listen
sockets to work with datagrams on Linux.
*) Change: the logging level of the "http request", "https proxy
request", "unsupported protocol", "version too low", "no suitable key
share", and "no suitable signature algorithm" SSL errors has been
lowered from "crit" to "info".
*) Bugfix: when using OpenSSL 1.1.0 or newer it was not possible to
switch off "ssl_prefer_server_ciphers" in a virtual server if it was
switched on in the default server.
*) Bugfix: nginx could not be built with LibreSSL 2.8.0.
*) Bugfix: if nginx was built with OpenSSL 1.1.0 and used with OpenSSL
1.1.1, the TLS 1.3 protocol was always enabled.
*) Bugfix: sending a disk-buffered request body to a gRPC backend might
fail.
*) Bugfix: connections with some gRPC backends might not be cached when
using the "keepalive" directive.
*) Bugfix: a segmentation fault might occur in a worker process if the
ngx_http_mp4_module was used on 32-bit platforms.
Changes with nginx 1.14.1 06 Nov 2018
*) Security: when using HTTP/2 a client might cause excessive memory
consumption (CVE-2018-16843) and CPU usage (CVE-2018-16844).
*) Security: processing of a specially crafted mp4 file with the
ngx_http_mp4_module might result in worker process memory disclosure
(CVE-2018-16845).
*) Bugfix: working with gRPC backends might result in excessive memory
consumption.
Changes with nginx 1.14.0 17 Apr 2018
*) 1.14.x stable branch.
Changes with nginx 1.13.12 10 Apr 2018
*) Bugfix: connections with gRPC backends might be closed unexpectedly
when returning a large response.
Changes with nginx 1.13.11 03 Apr 2018
*) Feature: the "proxy_protocol" parameter of the "listen" directive now
supports the PROXY protocol version 2.
*) Bugfix: nginx could not be built with OpenSSL 1.1.1 statically on
Linux.
*) Bugfix: in the "http_404", "http_500", etc. parameters of the
"proxy_next_upstream" directive.
Changes with nginx 1.13.10 20 Mar 2018
*) Feature: the "set" parameter of the "include" SSI directive now
allows writing arbitrary responses to a variable; the
"subrequest_output_buffer_size" directive defines maximum response
size.
*) Feature: now nginx uses clock_gettime(CLOCK_MONOTONIC) if available,
to avoid timeouts being incorrectly triggered on system time changes.
*) Feature: the "escape=none" parameter of the "log_format" directive.
Thanks to Johannes Baiter and Calin Don.
*) Feature: the $ssl_preread_alpn_protocols variable in the
ngx_stream_ssl_preread_module.
*) Feature: the ngx_http_grpc_module.
*) Bugfix: in memory allocation error handling in the "geo" directive.
*) Bugfix: when using variables in the "auth_basic_user_file" directive
a null character might appear in logs.
Thanks to Vadim Filimonov.
Changes with nginx 1.13.9 20 Feb 2018
*) Feature: HTTP/2 server push support; the "http2_push" and
"http2_push_preload" directives.
*) Bugfix: "header already sent" alerts might appear in logs when using
cache; the bug had appeared in 1.9.13.
*) Bugfix: a segmentation fault might occur in a worker process if the
"ssl_verify_client" directive was used and no SSL certificate was
specified in a virtual server.
*) Bugfix: in the ngx_http_v2_module.
*) Bugfix: in the ngx_http_dav_module.
Changes with nginx 1.13.8 26 Dec 2017
*) Feature: now nginx automatically preserves the CAP_NET_RAW capability
in worker processes when using the "transparent" parameter of the
"proxy_bind", "fastcgi_bind", "memcached_bind", "scgi_bind", and
"uwsgi_bind" directives.
*) Feature: improved CPU cache line size detection.
Thanks to Debayan Ghosh.
*) Feature: new directives in vim syntax highlighting scripts.
Thanks to Gena Makhomed.
*) Bugfix: binary upgrade refused to work if nginx was re-parented to a
process with PID different from 1 after its parent process has
finished.
*) Bugfix: the ngx_http_autoindex_module incorrectly handled requests
with bodies.
*) Bugfix: in the "proxy_limit_rate" directive when used with the
"keepalive" directive.
*) Bugfix: some parts of a response might be buffered when using
"proxy_buffering off" if the client connection used SSL.
Thanks to Patryk Lesiewicz.
*) Bugfix: in the "proxy_cache_background_update" directive.
*) Bugfix: it was not possible to start a parameter with a variable in
the "${name}" form with the name in curly brackets without enclosing
the parameter into single or double quotes.
Changes with nginx 1.13.7 21 Nov 2017
*) Bugfix: in the $upstream_status variable.
*) Bugfix: a segmentation fault might occur in a worker process if a
backend returned a "101 Switching Protocols" response to a
subrequest.
*) Bugfix: a segmentation fault occurred in a master process if a shared
memory zone size was changed during a reconfiguration and the
reconfiguration failed.
*) Bugfix: in the ngx_http_fastcgi_module.
*) Bugfix: nginx returned the 500 error if parameters without variables
were specified in the "xslt_stylesheet" directive.
*) Workaround: "gzip filter failed to use preallocated memory" alerts
appeared in logs when using a zlib library variant from Intel.
*) Bugfix: the "worker_shutdown_timeout" directive did not work when
using mail proxy and when proxying WebSocket connections.
Changes with nginx 1.13.6 10 Oct 2017
*) Bugfix: switching to the next upstream server in the stream module
did not work when using the "ssl_preread" directive.
*) Bugfix: in the ngx_http_v2_module.
Thanks to Piotr Sikora.
*) Bugfix: nginx did not support dates after the year 2038 on 32-bit
platforms with 64-bit time_t.
*) Bugfix: in handling of dates prior to the year 1970 and after the
year 10000.
*) Bugfix: in the stream module timeouts waiting for UDP datagrams from
upstream servers were not logged or logged at the "info" level
instead of "error".
*) Bugfix: when using HTTP/2 nginx might return the 400 response without
logging the reason.
*) Bugfix: in processing of corrupted cache files.
*) Bugfix: cache control headers were ignored when caching errors
intercepted by error_page.
*) Bugfix: when using HTTP/2 client request body might be corrupted.
*) Bugfix: in handling of client addresses when using unix domain
sockets.
*) Bugfix: nginx hogged CPU when using the "hash ... consistent"
directive in the upstream block if large weights were used and all or
most of the servers were unavailable.
Changes with nginx 1.13.5 05 Sep 2017
*) Feature: the $ssl_client_escaped_cert variable.
*) Bugfix: the "ssl_session_ticket_key" directive and the "include"
parameter of the "geo" directive did not work on Windows.
*) Bugfix: incorrect response length was returned on 32-bit platforms
when requesting more than 4 gigabytes with multiple ranges.
*) Bugfix: the "expires modified" directive and processing of the
"If-Range" request header line did not use the response last
modification time if proxying without caching was used.
Changes with nginx 1.13.4 08 Aug 2017
*) Feature: the ngx_http_mirror_module.
*) Bugfix: client connections might be dropped during configuration
testing when using the "reuseport" parameter of the "listen"
directive on Linux.
*) Bugfix: request body might not be available in subrequests if it was
saved to a file and proxying was used.

processing if the "resolver" directive was used, allowing an attacker
who is able to trigger name resolution to cause segmentation fault in
a worker process, or might have potential other impact
(CVE-2016-0746).
*) Security: CNAME resolution was insufficiently limited if the
"resolver" directive was used, allowing an attacker who is able to
trigger arbitrary name resolution to cause excessive resource
consumption in worker processes (CVE-2016-0747).
