. The gdImageScale*() and gdImageRotate*() helpers are now internal in the
bundled libgd, like they have been in external libgd as of gd-2.1.1.
- ext/json
. php_json_encode_serializable_object() now assumes `EG(active)`,
if not a bailout is caused. Therefore a minor BC break exists if the
`PHP_JSON_PARTIAL_OUTPUT_ON_ERROR` option is in use.
However, this situation is highly unlikely.
- ext/libxml
. The refcount APIs now return an `unsigned int` instead of an `int`.
