I like that too. For the record, I uploaded both to my server and did a compare. If anyone is curious:
Upgrade vs Full for beta3 (upload_full is the upload directory for the full version):
Only in upload_full: .htaccess (but there is a htaccess.txt, which is identical for both)
Only in upload_full: data (directory)
Only in upload_full: internal_data (directory)
