nginx 1.1.16
*) Change: the simultaneous subrequest limit has been raised to 200.
*) Feature: the "from" parameter of the "disable_symlinks" directive.
*) Feature: the "return" and "error_page" directives can be used to
return 307 redirections.
*) Bugfix: a segmentation fault might occur in a worker process if the
"resolver" directive was used and there was no "error_log" directive
specified at global level.
Thanks to Roman Arutyunyan.
*) Bugfix: a segmentation fault might occur in a worker process if the
"proxy_http_version 1.1" or "fastcgi_keep_conn on" directives were
used.
*) Bugfix: memory leaks.
Thanks to Lanshun Zhou.
*) Bugfix: in the "disable_symlinks" directive.
*) Bugfix: on ZFS filesystem disk cache size might be calculated

*) Bugfix: nginx could not be built by the icc 12.1 compiler.
