If you're creating a new plugin today, what are the latest resources? Most articles are from 2020-2022 and lots has happened since. It seems that some (all?) native plugins have two implements (one for K1 and one for K2). I'm assuming that FirDeclarationGenerationExtension is only for K2. If that's the case I'm wondering if it's even worth implementing support for K1 seeing that K2 is around the corner

That seems to be a great start for FIR plugins at least

And I've confirmed FIR is for K2 only.

As 2.0.0 is almost released, I wouldn’t expend time in K1

[ansman]

Yeah that's my conclusion too

Those docs link to samples using all extensions
