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 S..

*) 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.
