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.
