NEC3 ECC: Does anyone know of the change history between the ECSC 2005 and 2013?

This contract (and all others for that matter) in the first few pages of the book have a page that shows the amendments that have been made since the June 2005 edition. In the ECSC this is the page before page 1 (un-numbered). The only ones of any real note are the additional clauses in the compensation event section.
