nginx 0.6.7 *) Change: now the paths specified in the "include", "auth_basic_user_file", "perl_modules", "ssl_certificate", "ssl_certificate_key", and "ssl_client_certificate" directives are relative to directory of nginx configuration file nginx.conf, but not to nginx prefix directory. *) Change: the --sysconfdir=PATH option in configure was canceled. *) Change: the special make target "upgrade1" was defined for online upgrade of 0.1.x versions. *) Feature: the "server_name" and "valid_referers" directives support regular expressions. *) Feature: the "server" directive in the "upstream" context supports the "backup" parameter. *) Feature: the ngx_http_perl_module supports the $r->discard_request_body. *) Feature: the "add_header Last-Modified ..." directive changes the "Last-Modified" response header line. *) Bugfix: if an response different than 200 was returned to an request with body and connection went to the keep-alive state after the request, then nginx returned 400 for the next request. *) Bugfix: a segmentation fault occurred in worker process if invalid address was set in the "auth_http" directive. *) Bugfix: now nginx uses default listen backlog value 511 on all platforms except FreeBSD. Thanks to Jiang Hong. *) Bugfix: a worker process may got caught in an endless loop, if an "server" inside "upstream" block was marked as "down"; bug appeared in 0.6.6. *) Bugfix: now Solaris sendfilev() is not used to transfer the client request body to FastCGI-server via the unix domain socket.
