nginx 0.7.65 *) Security: now nginx/Windows ignores trailing spaces in URI. Thanks to Dan Crowley, Core Security Technologies. *) Security: now nginx/Windows ignores short files names. Thanks to Dan Crowley, Core Security Technologies. *) Change: now the "009" status code is written to an access log for proxied HTTP/0.9 responses. *) Change: now the default buffer size of the "large_client_header_buffers" directive is 8K. Thanks to Andrew Cholakian. *) Change: now default SSL ciphers are "HIGH:!ADH:!MD5". *) Change: now SSLv2 protocol is disabled by default. *) Change: now $host variable value is always low case. *) Feature: the conf/fastcgi.conf for simple FastCGI configurations. *) Feature: now URI part is not required a "proxy_pass" directive if variables are used. *) Feature: the $ssl_session_id variable. *) Bugfix: if a proxied or FastCGI request was internally redirected to another proxied or FastCGI location, then $upstream_response_time variable may have abnormally large value; the bug had appeared in 0.7.63. *) Bugfix: if the "expires modified" set date in the past, then a negative number was set in the "Cache-Control" response header line. Thanks to Alex Kapranoff. *) Bugfix: nginx closed a connection if a cached response had an empty body. Thanks to Piotr Sikora. *) Bugfix: nginx cached a 304 response if there was the "If-None-Match" header line in a proxied request. Thanks to Tim Dettrick and David Kostal. *) Bugfix: nginx did not treat a comma as separator in the "Cache-Control" backend response header line. *) Bugfix: cached HTTP/0.9 responses were handled incorrectly. *) Bugfix: nginx sent gzipped responses to clients those do not support gzip, if "gzip_static on" and "gzip_vary off"; the bug had appeared in 0.8.16. *) Bugfix: nginx always added "Content-Encoding: gzip" response header line in 304 responses sent by ngx_http_gzip_static_module. *) Bugfix: the "!-x" operator did not work. Thanks to Maxim Dounin. *) Bugfix: a segmentation fault might occur in a worker process, if limit_rate was used in HTTPS server. Thanks to Maxim Dounin. *) Bugfix: a segmentation fault might occur in a worker process while $limit_rate logging. Thanks to Maxim Dounin. *) Bugfix: nginx did not support dates in 2038 year on 32-bit platforms; *) Bugfix: nginx/Windows tried to delete a temporary file twice if the file should replace an already existent file. *) Bugfix: nginx/Windows tried to rename a temporary file twice if the file should replace an already existent file. *) Bugfix: nginx/Windows might not create temporary file, a cache file, or "proxy/fastcgi_store"d file if a worker had no enough access rights for top level directories. *) Bugfix: in UTF-8 encoding support by "try_files" directive in nginx/Windows. *) Bugfix: UTF-8 encoding usage in the ngx_http_autoindex_module. Thanks to Maxim Dounin. *) Bugfix: the ngx_http_autoindex_module did not show the trailing slash in links to a directory; the bug had appeared in 0.7.15. *) Bugfix: nginx did not close a log file set by the --error-log-path configuration option; the bug had appeared in 0.7.53. *) Bugfix: "addition_types" directive was incorrectly named "addtion_types". *) Bugfix: invalid request line in $request variable was written in access_log only if error_log was set to "info" or "debug" level.
