nginx 0.3.8 *) Security: nginx now checks URI got from a backend in "X-Accel-Redirect" header line or in SSI file for the "/../" paths and zeroes. *) Change: nginx now does not treat the empty user name in the "Authorization" header line as valid one. *) Feature: the "ssl_session_timeout" directives of the ngx_http_ssl_module and ngx_imap_ssl_module. *) Feature: the "auth_http_header" directive of the ngx_imap_auth_http_module. *) Feature: the "add_header" directive. *) Feature: the ngx_http_realip_module. *) Feature: the new variables to use in the "log_format" directive: $bytes_sent, $apache_bytes_sent, $status, $time_gmt, $uri, $request_time, $request_length, $upstream_status, $upstream_response_time, $gzip_ratio, $uid_got, $uid_set, $connection, $pipe, and $msec. The parameters in the "%name" form will be canceled soon. *) Change: now the false variable values in the "if" directive are the empty string "" and string starting with "0". *) Bugfix: while using proxied or FastCGI-server nginx may leave connections and temporary files with client requests in open state. *) Bugfix: the worker processes did not flush the buffered logs on graceful exit. *) Bugfix: if the request URI was changes by the "rewrite" directive and the request was proxied in location given by regular expression, then the incorrect request was transferred to backend; bug appeared in 0.2.6. *) Bugfix: the "expires" directive did not remove the previous "Expires" header. *) Bugfix: nginx may stop to accept requests if the "rtsig" method and several worker processes were used. *) Bugfix: the "\"" and "\'" escape symbols were incorrectly handled in SSI commands. *) Bugfix: if the response was ended just after the SSI command and gzipping was used, then the response did not transferred complete or did not transferred at all.
