I believe there have been no substantive changes (a few procedural changes excepted..) to MR2 post XV230, neither have there been any changes to the design of MRA4.
If the BOI come up with any change recommendations, I for one (as a UK taxpayer) will want to know why it’s taken over 14 months (to date) to decide that changes are necessary (that’s 14 months of flying to date (& more tomorrow) without any changes…)).
