The engines built today are exactly the same as the very first ones produced. That’s the entire point of the LO206 program…
That is what is nice about it. It is a great thing in that respect. It does not force you to upgrade. A real pain when you just bought in and then a mfgr drops a new upgrade right after you just shelled out money on an initial investment.
I find the LO206 pretty hassle free overall in terms of the overall package. For fun and entry level it is an obvious choice.
