nginx-0.1.18-RELEASE importrelease-0.1.18

    *) Workaround: the default values of the devpoll_events and the
       devpoll_changes directives changed from 512 to 32 to be compatible
       with Solaris 10.

    *) Bugfix: the proxy_set_x_var and fastcgi_set_var directives were not
       inherited.

    *) Bugfix: in the redirect rewrite directive the arguments were
       concatenated with URI by the "&" rather than the "?".

    *) Bugfix: the lines without trailing ";" in the file being included by
       the ngx_http_geo_module were silently ignored.

    *) Feature: the ngx_http_stub_status_module.

    *) Bugfix: the unknown log format in the access_log directive caused
       the segmentation fault.

    *) Feature: the new "document_root" parameter of the fastcgi_params
       directive.

    *) Feature: the fastcgi_redirect_errors directive.

    *) Feature: the new "break" modifier of the "rewrite" directive allows
       to stop the rewrite/location cycle and sets the current
       configuration to the request.
