Not sure how many people use a script to download the latest build of CB, but their change to '1.0.x' has been a royal pain to deal with with the current shell script I use. Instead of using their convoluted download-a-zip approach, I've created a PHP script that just gets the URL for the latest version (RB or edge) and does an HTTP redirect to it, huzzah:
http://thedgtl.net/bukkit/j.phpYou can view the source here, nothing malicious, I promise
http://pastebin.com/jnTdDcaPAnd if you want the latest edge build (Bleeding edge, non-RB) you can use the URL:
http://thedgtl.net/bukkit/j.php?edge
