hook_mp_file_name from the heaviest module takes precedence over lighter modules.

Code operated differently based on the db used (mysql vs pgsql).  Code is now database insensitive.

May need more thought but let's get 6.x functional for starters...

'callback' changed to 'page callback' for 6.x compatibility as in http://drupal.org/node/103114

the starting point for developing a 6.x release.  Further addition of new features for 6.x
will be minimal as stabilization of this version of mp_file will be a priority.

http://drupal.org/node/663326 - File requirement feature (may still need work)
http://drupal.org/node/594844 - Commit checkbox initial value (fixed)
http://drupal.org/node/595008 - File can be named by the user through a hook (fixed?)
http://drupal.org/node/608464 - Should be fixed as in 595008
http://drupal.org/node/601980 - Permission to "Administer own product features" added
Drupal coding standard compliant
A few more admin checkboxes under seller configuration
and a few other changes...
