Changes with nginx 0.8.20 14 Oct 2009

    *) 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.
