Thank you for the summary philidor.
Regarding the hydraulic temperature issue, this was mentioned by Airbus during the Innovation Days in May.
Regarding the startup time: this has been reduced from 3 minutes to just 90 seconds, and will be further reduced to ~ 70 seconds this autumn. Note that 90 seconds is already pretty good (in line with the current V2500 engine).
That cannot be right, we are already in Q3 and flight activity has resumed to 'normal' since early this month.
Perhaps, though 90 seconds should be fine for many operators.

The A320neo ramp up and delivery schedule is expected to be back on track in Q2 this year.

The second tweak being promised no sooner than September may still lead some customers not to take delivery until Q4.

PW1400G-JM geared turbofan engine, aimed for the Irkut MS-21-300 aircraft, share the same, not just the engine architecture, but the fan´s and core´s geometry (fan diameter: 2.057,4 mm / 81,0 in; eng. architecture: F]G[3LPC-8HPC ^ 2HPT-3LPT) with the PW1100G-JM engine (among some differences in engines´ design, like the accessory drives and the secondary subsystems generally, the engines differ in FADEC Hardware & Software PN and Data Storage Unit PN - Ratings Plug), I expect that, until the first flight, Irkut MS-21-300 first prototype will get a new pair of the engines and that with all the construction and software modifications already implemented in the PW1100G-JM engine aimed for the 
A320neo family of the aircraft.
