   . Removed ability to use array_key_exists() with objects. Use one of isset()
     or property_exists() instead.
+  . Made the behavior of array_key_exists() regarding the type of the key
+    parameter consistent with isset() and normal array access. All key types now use
+    the usual coercions and array/object keys throw a TypeError.
   . Any array that has a number n as its first numeric key will use n+1 for
     its next implicit key. Even if n is negative.
