Changes with nginx 1.15.12 16 Apr 2019

ngx_http_mp4_module was used on 32-bit platforms.
Changes with nginx 1.15.6 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).
*) Feature: the "proxy_socket_keepalive", "fastcgi_socket_keepalive",
"grpc_socket_keepalive", "memcached_socket_keepalive",
"scgi_socket_keepalive", and "uwsgi_socket_keepalive" directives.
*) 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.

consumption.
Changes with nginx 1.15.5 02 Oct 2018
*) Bugfix: a segmentation fault might occur in a worker process when
using OpenSSL 1.1.0h or newer; the bug had appeared in 1.15.4.
*) Bugfix: of minor potential bugs.
Changes with nginx 1.15.4 25 Sep 2018
*) Feature: now the "ssl_early_data" directive can be used with OpenSSL.
*) Bugfix: in the ngx_http_uwsgi_module.
Thanks to Chris Caputo.
*) Bugfix: connections with some gRPC backends might not be cached when
using the "keepalive" directive.
*) Bugfix: a socket leak might occur when using the "error_page"
directive to redirect early request processing errors, notably errors
with code 400.
*) Bugfix: the "return" directive did not change the response code when
returning errors if the request was redirected by the "error_page"
directive.
*) Bugfix: standard error pages and responses of the
ngx_http_autoindex_module module used the "bgcolor" attribute, and
might be displayed incorrectly when using custom color settings in
browsers.
Thanks to Nova DasSarma.
*) Change: the logging level of the "no suitable key share" and "no
suitable signature algorithm" SSL errors has been lowered from "crit"
to "info".
Changes with nginx 1.15.3 28 Aug 2018
*) Feature: now TLSv1.3 can be used with BoringSSL.
*) Feature: the "ssl_early_data" directive, currently available with
BoringSSL.
*) Feature: the "keepalive_timeout" and "keepalive_requests" directives
in the "upstream" block.
*) Bugfix: the ngx_http_dav_module did not truncate destination file
when copying a file over an existing one with the COPY method.
*) Bugfix: the ngx_http_dav_module used zero access rights on the
destination file and did not preserve file modification time when
moving a file between different file systems with the MOVE method.
*) Bugfix: the ngx_http_dav_module used default access rights when
copying a file with the COPY method.
*) Workaround: some clients might not work when using HTTP/2; the bug
had appeared in 1.13.5.
*) Bugfix: nginx could not be built with LibreSSL 2.8.0.
Changes with nginx 1.15.2 24 Jul 2018
*) Feature: the $ssl_preread_protocol variable in the
ngx_stream_ssl_preread_module.
*) Feature: now when using the "reset_timedout_connection" directive
nginx will reset connections being closed with the 444 code.
*) Change: a logging level of the "http request", "https proxy request",
"unsupported protocol", and "version too low" SSL errors has been
lowered from "crit" to "info".
*) Bugfix: DNS requests were not resent if initial sending of a request
failed.
*) Bugfix: the "reuseport" parameter of the "listen" directive was
ignored if the number of worker processes was specified after the
"listen" directive.
*) 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: SSL session reuse with upstream servers did not work with the
TLS 1.3 protocol.
Changes with nginx 1.15.1 03 Jul 2018
*) Feature: the "random" directive inside the "upstream" block.

directives with the "zone" directive.

connections.
*) Bugfix: sending a disk-buffered request body to a gRPC backend might
fail.
Changes with nginx 1.15.0 05 Jun 2018
*) Change: the "ssl" directive is deprecated; the "ssl" parameter of the
"listen" directive should be used instead.
*) Change: now nginx detects missing SSL certificates during
configuration testing when using the "ssl" parameter of the "listen"
directive.
*) Feature: now the stream module can handle multiple incoming UDP
datagrams from a client within a single session.

"proxy_cache_valid" directive.
