nginx-0.3.12-RELEASE importrelease-0.3.12

    *) Security: if nginx was built with the ngx_http_realip_module and the
       "satisfy_any on" directive was used, then access and authorization
       directives did not work. The ngx_http_realip_module was not built
       and is not built by default.

    *) Change: the "$time_gmt" variable name was changed to "$time_local".

    *) Change: the "proxy_header_buffer_size" and
       "fastcgi_header_buffer_size" directives was renamed to the
       "proxy_buffer_size" and "fastcgi_buffer_size" directives.

    *) Feature: the ngx_http_memcached_module.

    *) Feature: the "proxy_buffering" directive.

    *) Bugfix: the changes in accept mutex handling when the "rtsig" method
       was used; the bug had appeared in 0.3.0.

    *) Bugfix: if the client sent the "Transfer-Encoding: chunked" header
       line, then nginx returns the 411 error.

    *) Bugfix: if the "auth_basic" directive was inherited from the http
       level, then the realm in the "WWW-Authenticate" header line was
       without the "Basic realm" text.

    *) Bugfix: if the "combined" format was explicitly specified in the
       "access_log" directive, then the empty lines was written to the log;
       the bug had appeared in 0.3.8.

    *) Bugfix: nginx did not run on the sparc platform under any OS except
       Solaris.

    *) Bugfix: now it is not necessary to place space between the quoted
       string and closing bracket in the "if" directive.
