nginx 0.5.1
*) Bugfix: the "post_action" directive might not run after a
unsuccessful completion of a request.
*) Workaround: for Eudora for Mac; bug appeared in 0.4.11.
Thanks to Bron Gondwana.
*) Bugfix: if the "upstream" name was used in the "fastcgi_pass", then
the message "no port in upstream" was issued; bug appeared in 0.5.0.
*) Bugfix: if the "proxy_pass" and "fastcgi_pass" directives used the
same servers but different ports, then these directives uses the
first described port; bug appeared in 0.5.0.
*) Bugfix: if the "proxy_pass" and "fastcgi_pass" directives used the
unix domain sockets, then these directives used first described
socket; bug appeared in 0.5.0.
*) Bugfix: ngx_http_auth_basic_module ignored the user if it was in the
last line in the password file and there was no the carriage return,
the line feed, or the ":" symbol after the password.
*) Bugfix: the $upstream_response_time variable might be equal to
"0.000", although response time was more than 1 millisecond.
