As far as I can see there is no artwork change between v1.1 and v1.2. Only the values have changed.

That is what I used to begin with bu there a several differences to the PCBs.
Nice work, what is core material with this big gap? BD241 must have heatsink.

I install the heat sink, I do not have it, I need to buy. Material 2000NM core, you can put a ring on EPCOS. The size 45*28*12
