Changes with nginx 0.6.27 12 Mar 2008 ``` *) Change: now by default the rtsig method is not built on Linux 2.6.18+. *) Change: now a request method is not changed while redirection to ``` a named location via an “error\_page” directive. ``` *) Feature: the "resolver" and "resolver_timeout" directives in SMTP proxy. *) Feature: the "post_action" directive supports named locations. *) Bugfix: a segmentation fault occurred in worker process, if a request was redirected from proxy, FastCGI, or memcached location ``` to static named locations. ``` *) Bugfix: browsers did not repeat SSL handshake if there is no ``` valid client certificate in first handshake. Thanks to Alexander V. Inyukhin. ``` *) Bugfix: if response code 495-497 was redirected via an ``` “error\_page” directive without code change, then nginx tried to allocate too many memory. ``` *) Bugfix: memory leak in long-lived non buffered connections. *) Bugfix: memory leak in resolver. *) Bugfix: a segmentation fault occurred in worker process, if a request was redirected from proxy, FastCGI, or memcached location ``` to static named locations. ``` *) Bugfix: in the $proxy_host and $proxy_port variables caching. Thanks to Sergey B.. *) Bugfix: a "proxy_pass" directive with variables used incorrectly ``` the same port as in another “proxy\_pass” directive with the same host name and without variables. Thanks to Sergey B… ``` *) Bugfix: an alert "sendmsg() failed (9: Bad file descriptor)" on ``` some 64-bit platforms while reconfiguration. ``` *) Bugfix: a segmentation fault occurred in worker process, if empty stub block was used second time in SSI. *) Bugfix: in copying URI part contained escaped symbols into ``` arguments. ---

Many incompatibilies will be showed by nginx -t Other incompatibilies: ``` *) 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. and since 0.6.25 $server\_name is always the first name in server\_name. ---
