• the construction chapter has been substantially expanded to provide more detailed coverage of the courts' general approach to construction, the evidence that may be taken into account (including more detailed discussion of particular categories of extrinsic evidence), the role of contractual purposes and absurdity;
• in the implied terms chapter, implication for business efficacy and terms implied in law are discussed in greater detail;
• in the restrictions on termination chapter, the sections on the readiness and willingness requirement and relief against forfeiture have been expanded and made clearer;
