nginx 0.5.0 *) Change: the parameters in the "%name" form in the "log_format" directive are not supported anymore. *) Change: the "proxy_upstream_max_fails", "proxy_upstream_fail_timeout", "fastcgi_upstream_max_fails", "fastcgi_upstream_fail_timeout", "memcached_upstream_max_fails", and "memcached_upstream_fail_timeout" directives are not supported anymore. *) Feature: the "server" directive in the "upstream" context supports the "max_fails", "fail_timeout", and "down" parameters. *) Feature: the "ip_hash" directive inside the "upstream" block. *) Feature: the WAIT status in the "Auth-Status" header line of the IMAP/POP3 proxy authentication server response. *) Bugfix: nginx could not be built on 64-bit platforms; bug appeared in 0.4.14.
