nginx 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; bug 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; bug 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.
