Do I need to do anything else? Unlike what the comment in boostrapexternal.py suggests, this "magic tag" will not change every time a bytecode is added, but only on every minor release. Which implies that if we have a micro release that adds an opcode, we'll in fact break the promise in the comment. You will want to bump the number on the following line: https://hg.python.org/cpython/file/default/Lib/importlib/bootstrapexternal.py#l231

Thanks. That part I've done (but forgot to mention). I was just concerned about the "magic tag" part, which Barry cleared up.
