Broken down, the new elements are the inclusion of the suspended bits (discussed more below), the revised entry into force (necessary after the US pulled out), a new section on withdrawal (the necessity of which was made crystal clear after the US pulled out), a new section on accession (since the old one was too vague anyway), a potentially interesting article 6 that seems to review the whole agreement in the future, and article 7 that copies across all of the original commitments and texts from TPP12.  What this means in practice is that the CPTPP or TPP11 has identical schedules and commitments for members to TPP12.  Everyone should start pulling out their TPP12 materials and reviewing documents to refresh memories now.  Firms need to prepare for entry into force which is coming up fast.
