    previous behavior.

*   Performing equality operations on Tensors or Variables with incompatible
    shapes an exception is no longer thrown. Instead `__eq__` returns False and
    `__ne__` returns True.

*   Removed `tf.string_split` from v2 API.

*   Deprecated the use of `constraint=` and `.constraint` with ResourceVariable.
