nginx-0.1.29-RELEASE importrelease-0.1.29

    *) Feature: the ngx_http_ssi_module supports "include virtual" command.

    *) Feature: the ngx_http_ssi_module supports the condition command like
       'if expr="$NAME"' and "else" and "endif" commands. Only one nested
       level is supported.

    *) Feature: the ngx_http_ssi_module supports the DATE_LOCAL and
       DATE_GMT variables and "config timefmt" command.

    *) Feature: the "ssi_ignore_recycled_buffers" directive.

    *) Bugfix: the "echo" command did not show the default value for the
       empty QUERY_STRING variable.

    *) Change: the ngx_http_proxy_module was rewritten.

    *) Feature: the "proxy_redirect", "proxy_pass_request_headers",
       "proxy_pass_request_body", and "proxy_method" directives.

    *) Feature: the "proxy_set_header" directive. The "proxy_x_var" was
       canceled and must be replaced with the proxy_set_header directive.

    *) Change: the "proxy_preserve_host" is canceled and must be replaced
       with the "proxy_set_header Host $host" and the "proxy_redirect off"
       directives, the "proxy_set_header Host $host:$proxy_port" directive
       and the appropriate proxy_redirect directives.

    *) Change: the "proxy_set_x_real_ip" is canceled and must be replaced
       with the "proxy_set_header X-Real-IP $remote_addr" directive.

    *) Change: the "proxy_add_x_forwarded_for" is canceled and must be
       replaced with
       the "proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for"
       directive.

    *) Change: the "proxy_set_x_url" is canceled and must be replaced with
       the "proxy_set_header X-URL http://$host:$server_port$request_uri"
       directive.

    *) Feature: the "fastcgi_param" directive.

    *) Change: the "fastcgi_root", "fastcgi_set_var" and "fastcgi_params"
       directive are canceled and must be replaced with the fastcgi_param
       directives.

    *) Feature: the "index" directive can use the variables.

    *) Feature: the "index" directive can be used at http and server levels.

    *) Change: the last index only in the "index" directive can be absolute.

    *) Feature: the "rewrite" directive can use the variables.

    *) Feature: the "internal" directive.

    *) Feature: the CONTENT_LENGTH, CONTENT_TYPE, REMOTE_PORT, SERVER_ADDR,
       SERVER_PORT, SERVER_PROTOCOL, DOCUMENT_ROOT, SERVER_NAME,
       REQUEST_METHOD, REQUEST_URI, and REMOTE_USER variables.

    *) Change: nginx now passes the invalid lines in a client request
       headers or a backend response header.

    *) Bugfix: if the backend did not transfer response for a long time and
       the "send_timeout" was less than "proxy_read_timeout", then nginx
       returned the 408 response.

    *) Bugfix: the segmentation fault was occurred if the backend sent an
       invalid line in response header; the bug had appeared in 0.1.26.

    *) Bugfix: the segmentation fault may occurred in FastCGI fault
       tolerance configuration.

    *) Bugfix: the "expires" directive did not remove the previous
       "Expires" and "Cache-Control" headers.

    *) Bugfix: nginx did not take into account trailing dot in "Host"
       header line.

    *) Bugfix: the ngx_http_auth_module did not work under Linux.

    *) Bugfix: the rewrite directive worked incorrectly, if the arguments
       were in a request.

    *) Bugfix: nginx could not be built on MacOS X.
