       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".

       directive in the upstream block if large weights were used and all or
       most of the servers were unavailable.

Log message:
Changes with nginx 1.13.3:

*) Security: a specially crafted request might result in an integer
   overflow and incorrect processing of ranges in the range filter,
   potentially resulting in sensitive information leak (CVE-2017-7529).

*) Change: nginx now returns 200 instead of 416 when a range starting
   with 0 is requested from an empty file.

   appeared in 1.13.0.

   directive parameter.

   using OpenSSL before 1.1.0.

*) Workaround: nginx could not be built with Oracle Developer Studio
   12.5.

*) Workaround: now cache manager ignores long locked cache entries when
   cleaning cache based on the "max_size" parameter.

   accept and the "proxy_protocol" parameter of the "listen" \ 
directive
   were used.

       $ssl_client_i_dn_legacy variables.

    *) Change: when storing temporary files in a cache directory they will
       be stored in the same subdirectories as corresponding cache files

  while writing a specially crafted request body to a temporary
  file (CVE-2016-4450); the bug had appeared in 1.3.9.

Changes with nginx 1.11.0

- Feature: the "transparent" parameter of the "proxy_bind",
  "fastcgi_bind", "memcached_bind", "scgi_bind", \ 
and "uwsgi_bind"
  directives.

- Feature: the $request_id variable.

- Feature: the "map" directive supports combinations of multiple
  variables as resulting values.

  kernel, and optimizes connection handling accordingly if the
  "epoll" method is used.

- Feature: the "ssl_certificate" and "ssl_certificate_key"
  directives can be specified multiple times to load certificates
  of different types (for example, RSA and ECDSA).

- Feature: the "ssl_ecdh_curve" directive now allows specifying a
  list of curves when using OpenSSL 1.0.2 or newer; by default
  a list built into OpenSSL is used.

  rejecting requests to a virtual server different from one
  negotiated during an SSL handshake; this improves interoperability
  with some HTTP/2 clients when using client certificates.

- Change: HTTP/2 clients can now start sending request body
  immediately; the "http2_body_preread_size" directive controls
  size of the buffer used before nginx will start reading client
  request body.

- Bugfix: cached error responses were not updated when using the
  "proxy_cache_bypass" directive.

Changes with nginx 1.9.15

- Bugfix: "recv() failed" errors might occur when using HHVM as a
  FastCGI server.

- Bugfix: when using HTTP/2 and the "limit_req" or "auth_request"
  directives a timeout or a "client violated flow control" error
  might occur while reading client request body; the bug had appeared

  HTTP/2 was used and client request body was not fully read; the
  bug had appeared in 1.9.14.

  when using HTTP/2.

- Bugfix: the "client_max_body_size" directive might work
  incorrectly when using HTTP/2.

- Bugfix: of minor bugs in logging.

Changes with nginx 1.9.13

- Change: non-idempotent requests (POST, LOCK, PATCH) are no
  longer passed to the next server by default if a request has
  been sent to a backend; the "non_idempotent" parameter of the
  "proxy_next_upstream" directive explicitly allows retrying such
  requests.

- Feature: the ngx_http_perl_module can be built dynamically.

- Feature: UDP support in the stream module.

- Feature: the "aio_write" directive.

- Feature: now cache manager monitors number of elements in caches
  and tries to avoid cache keys zone overflows.

might
  appear in logs when using the "sendfile" and "aio" directives
  with subrequests.

  caching was used.
  Thanks to Justin Li.

  on Linux or Solaris and a file being sent was changed during
  sending.

- Bugfix: connections might hang when using the "sendfile" and
  "aio threads" directives.

- Bugfix: in the "proxy_pass", "fastcgi_pass", \ 
"scgi_pass", and

- Bugfix: if an error occurred in a cached backend connection, the
  request was passed to the next server regardless of the
  proxy_next_upstream directive.

- Bugfix: "CreateFile() failed" errors when creating temporary
  files on Windows.

Changes with nginx 1.9.12

- Feature: Huffman encoding of response headers in HTTP/2.
  Thanks to Vlad Krasnov.

- Feature: the "worker_cpu_affinity" directive now supports more
  than 64 CPUs.

- Bugfix: compatibility with 3rd party C++ modules; the bug had
  appeared in 1.9.11.
  Thanks to Piotr Sikora.

- Bugfix: nginx could not be built statically with OpenSSL on
  Linux; the bug had appeared in 1.9.11.

- Bugfix: the "add_header ... always" directive with an empty
  value did not delete "Last-Modified" and "ETag" header lines
  from error responses.
