This page contains information about updating the various stable links to part of CLDR and "latest" versions, etc. Most of the redirects are in the ".htaccess" file of http://www.unicode.org/cldr/ and some are in the /etc/apache2/httpd-rewrite.conf file on www.unicode.org. (Note: at this point, you should not have to touch cldr/.htaccess which should be stable, just the rewrite conf file.)
