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.
