Changes with nginx 1.5.11                                        04 Mar 2014

    *) Security: memory corruption might occur in a worker process on 32-bit
       platforms while handling a specially crafted request by
       ngx_http_spdy_module, potentially resulting in arbitrary code
       execution (CVE-2014-0088); the bug had appeared in 1.5.10.
       Thanks to Lucas Molas, researcher at Programa STIC, Fundación Dr.
       Manuel Sadosky, Buenos Aires, Argentina.

    *) Feature: the $ssl_session_reused variable.

    *) Bugfix: the "client_max_body_size" directive might not work when
       reading a request body using chunked transfer encoding; the bug had
       appeared in 1.3.9.
       Thanks to Lucas Molas.

    *) Bugfix: a segmentation fault might occur in a worker process when
       proxying WebSocket connections.

    *) Bugfix: a segmentation fault might occur in a worker process if the
       ngx_http_spdy_module was used on 32-bit platforms; the bug had
       appeared in 1.5.10.

    *) Bugfix: the $upstream_status variable might contain wrong data if the
       "proxy_cache_use_stale" or "proxy_cache_revalidate" directives were
       used.
       Thanks to Piotr Sikora.

    *) Bugfix: a segmentation fault might occur in a worker process if
       errors with code 400 were redirected to a named location using the
       "error_page" directive.

    *) Bugfix: nginx/Windows could not be built with Visual Studio 2013.
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.
