I don't understand that part. We don't support binary compatibility with binaries compiled for -CURRENT or pre-release libraries, do we? Bumping it now would allow using 6-STABLE binaries on -CURRENT, which is my main point here. If we ever break ABI in -CURRENT later on not a big deal, because no vendor should compile its production binaries for -CURRENT anyway. -Maxim
