 The new macros can be polyfilled for older PHP versions, which is also why this introduces new macros rather than modifying existing ones.
+The ''zend_hash_get_current_key(_ex)'' function is removed. Instead, one of the following two functions can be used (where the former already exists on older PHP versions, while the latter is more efficient):
+<code c>
+/* This function populates `key` with a copy of the key, or a null zval if exhausted. */
+ZEND_API void  ZEND_FASTCALL zend_hash_get_current_key_zval_ex(const HashTable *ht, zval *key, HashPosition *pos);
+/* This function returns the key zval directly, or NULL if exhausted. */
+ZEND_API zval* ZEND_FASTCALL zend_hash_get_current_zkey(const HashTable *ht, HashPosition *pos);
+</code>
+The ''zend_hash_get_current_key_type(_ex)'' function and the ''HASH_KEY_IS_LONG'', ''HASH_KEY_IS_STRING'' and ''HASH_KEY_NON_EXISTENT'' constants are also removed, and should be replaced by taking the type of the key zval.
