And what is here? Between 88 and 121?

I found in changelog:
"fix license issue, it's GPL-2.0+ only in the current version"
and I do not understand.

The license is wrong, so what did you fix?

Probably I asked about this... why indices are not continuous? You know
that consumers are allowed to use number 2 and it will be your ABI, even
though you did not write it in the binding? That's a tricky and
confusing pattern for no real gains.
