It is a > behavior change, so it should be confined to master branch. Not sure about that part. I think both changes should be considered as bug fixes and as such should also be eligible for 5.3/5.4. The set_error_handler(null) change has no impact on BC whatsoever and the return value change only has a theoretical BC impact (why would you check the return value if it is *always* true?) Nikita
