@n1ru4l I think this is ready for your review.

[saihaj]

we also want to upgrade codegen version before we merge this so it is a single major bump. So let's sequence all those in one release.

[saihaj]

@domdomegg looks like we have some conflicts, can you help resolve those?

[HermanBilous]

@saihaj, This change should be obsolete since #348 already dropped support for v12 and v14.

[saihaj]

thank you
