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.
