For the URLs under 'latest/' the server returns a "301 Moved 
Permanently" response, which is used to indicate that the original URL 
is no longer in use and that references to it should be updated to the 
target URL [1]. Hence, search engines will only index the targets of the 
redirects and ignore the original URLs [2]. Using a "302 Found" redirect 
instead might produce better results, at least for Google [2].
