I'm getting ready to get back into an old personal project with some new ideas. Before I do, I need to ask a question regarding the stability of CPython bytecode. Before you say it, I am well aware and fully understand that the opcodes may change in value and semantics between 3.x and 3.(x+1) without notice, and that's acceptable to me.
My question is, are the opcodes guaranteed stable across the lifetime of a single 3.x release? In other words, are they guaranteed to not change values or semantics between 3.x.y and 3.x.(y+1)? Reading through the list of opcodes in the dis documentation, it seems that all changes have occurred in 3.x.0, so it seems the answer would be yes, but then the "CPython implementation detail" paragraph at the top doesn't specify that and is a little vague on whether that's true or not. (For context, my personal project is a BASIC implementation in Python that would compile to Python bytecode.)
