Hello, I've got a question about the release notes: Can it really be called binary compatible if it can introduce breakage in userland? I think that the required changes to userland are quite minimal but I'd understand binary compatible in a way that replacing a 9.0.0 binary by a 9.0.1 binary should'nt introduce any troubles at all, which according to the patch notes isn't really the case (at least on 64-bit arches.
