[Maxim Dounin]

Changes with nginx 1.2.1                                         05 Jun 2012

    *) Security: now nginx/Windows ignores trailing dot in URI path
       component, and does not allow URIs with ":$" in it.
       Thanks to Vladimir Kochetkov, Positive Research Center.

    *) Feature: the "debug_connection" directive now supports IPv6 addresses
       and the "unix:" parameter.

    *) Feature: the "set_real_ip_from" directive and the "proxy" parameter
       of the "geo" directive now support IPv6 addresses.

    *) Feature: the "real_ip_recursive", "geoip_proxy", and
       "geoip_proxy_recursive" directives.

    *) Feature: the "proxy_recursive" parameter of the "geo" directive.

    *) Bugfix: a segmentation fault might occur in a worker process if the
       "resolver" directive was used.

    *) Bugfix: a segmentation fault might occur in a worker process if the
       "fastcgi_pass", "scgi_pass", or "uwsgi_pass" directives were used and
       backend returned incorrect response.

    *) Bugfix: a segmentation fault might occur in a worker process if the
       "rewrite" directive was used and new request arguments in a
       replacement used variables.

    *) Bugfix: nginx might hog CPU if the open file resource limit was
       reached.

    *) Bugfix: nginx might loop infinitely over backends if the
       "proxy_next_upstream" directive with the "http_404" parameter was
       used and there were backup servers specified in an upstream block.

    *) Bugfix: adding the "down" parameter of the "server" directive might
       cause unneeded client redistribution among backend servers if the
       "ip_hash" directive was used.

    *) Bugfix: socket leak.
       Thanks to Yichun Zhang.

    *) Bugfix: in the ngx_http_fastcgi_module.
