Well, either I misunderstood the policy or it's broken. Here are some (note: please do not argue whether these are more correct than before, they very well might be but they broke backwards compatibility): For example, in 5.4 array_diff_assoc began to throw a notice when casting to string. Again in 5.4, using a string offset against a string throws a warning. It wasn't doing that before. If you want I can dig around in our issue queue for more backwards compatibility breaks but there are some.
