nginx 0.8.20
*) Change: now default SSL ciphers are "HIGH:!ADH:!MD5".
*) 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: nginx did not treat a comma as separator in the
"Cache-Control" backend response header line.
*) Bugfix: nginx/Windows might not create temporary file, a cache file,
or "proxy/fastcgi_store"d file if a worker has no enough access
rights for top level directories.
*) Bugfix: the "Set-Cookie" and "P3P" FastCGI response header lines
were not hidden while caching if no "fastcgi_hide_header" directives
were used with any parameters.
*) Bugfix: nginx counted incorrectly disk cache size.
