Millions of web sites on the Internet use and benefit from Nginx because of its extreme performance, scalability, reliability, flexibility, and security.

On 2016-03-29, the mainline version of Nginx 1.9.13 was released at The upstream changelog is as follows:

Changes with nginx 1.9.13 — 29 Mar 2016

  • ) 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.
  • ) Bugfix: “task already active” and “second aio post” alerts might appear in logs when using the “sendfile” and “aio” directives with subrequests.
  • ) Bugfix: “zero size buf in output” alerts might appear in logs if caching was used and a client closed a connection prematurely.
  • ) Bugfix: connections with clients might be closed needlessly if caching was used. Thanks to Justin Li.
  • ) Bugfix: nginx might hog CPU if the “sendfile” directive was used 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 “uwsgi_pass” directives when using variables. Thanks to Piotr Sikora.
  • ) Bugfix: in the ngx_http_sub_filter_module.
  • ) 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.
