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.
