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

"Cache-Control" backend response header line.
*) Bugfix: cached HTTP/0.9 responses were handled incorrectly.

gzip, if "gzip_static on" and "gzip_vary off"; the bug had appeared

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.

Thanks to Maxim Dounin.
*) Bugfix: nginx did not support dates in 2038 year on 32-bit platforms;

file should replace an already existent file.
*) Bugfix: nginx/Windows tried to rename a temporary file twice if the

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.
