This agreement means that the main issue that created a lasting tension between Qatar Airways and Airbus has been settled, which probably explains the recent resumption of A350 deliveries by the airline.
Bit of a blow to Pratt isn't it? Although not so much of a surprise anymore.
With these changes, Pratt is certainly the only losing party. QR refused to take delivery of the first A320neo in December 2015, and did not budge later. It seems the temperature issue they raised then could not be solved to their satisfaction.
