Changes with nginx 1.5.12                                        18 Mar 2014

    *) Security: a heap memory buffer overflow might occur in a worker
       process while handling a specially crafted request by
       ngx_http_spdy_module, potentially resulting in arbitrary code
       execution (CVE-2014-0133).
       Thanks to Lucas Molas, researcher at Programa STIC, Fundación Dr.
       Manuel Sadosky, Buenos Aires, Argentina.

    *) Feature: the "proxy_protocol" parameters of the "listen" and
       "real_ip_header" directives, the $proxy_protocol_addr variable.

    *) Bugfix: in the "fastcgi_next_upstream" directive.
       Thanks to Lucas Molas.

    *) Change: improved hash table handling; the default values of the
       "variables_hash_max_size" and "types_hash_bucket_size" were changed
       to 1024 and 64 respectively.

    *) Feature: the ngx_http_mp4_module now supports the "end" argument.

    *) Feature: byte ranges support in the ngx_http_mp4_module and while
       saving responses to cache.

    *) Bugfix: alerts "ngx_slab_alloc() failed: no memory" no longer logged
       when using shared memory in the "ssl_session_cache" directive and in
       the ngx_http_limit_req_module.

    *) Bugfix: the "underscores_in_headers" directive did not allow
       underscore as a first character of a header.
       Thanks to Piotr Sikora.

    *) Bugfix: cache manager might hog CPU on exit in nginx/Windows.

    *) Bugfix: nginx/Windows terminated abnormally if the
       "ssl_session_cache" directive was used with the "shared" parameter.

    *) Bugfix: in the ngx_http_spdy_module.
