to the newest. It would try to change tables that had not yet been created
  causing major problems to the node module. (NOTE: if you are doing a x.xx
  update to another x.xx version you might have to force MySQL to perform it
  using the -f flag. Remember to always backup your data before making
  changes).
- Prevented 2.00-to-x.xx.php from executing. It would simply give a PHP error
  and not execute. Will wait for Dries to return before attempting to make it
  functional or remove it.
