For the non Japanese speaking (that would include me) data of the 2019 model. After all, it does get a little more power, with a higher redline (7500rpm, up form 6800 and 181hp, up form 155).
It is still far form a muscle car, but 181ho in a car of approx. 1000kg is still a lot of fun, especially with a RWD chassis (and a very good one), and especially if it is of the naturally aspirated sort (which it is here). Also, a telescoping steering wheel is added for those poor tall people (again, including me), as well as an updated infotainment system with a new (slightly larger) screen.
Let#s not forget, the original Miata weighed roughly the same, was the same size and had 60% of the power; Most cars have indeed also increased their power by the same percentage or even doubled it in the last 3 decades (let's take a Golf GTI, gone form 129hp to 220/230, and that is a quick car still), but also nearly doubled their weight (or at least 50% increase in weight as well), so I still think that the MX5 does not deserve all the bashing it gets power wise...
