+modulus operator support added for ``np.timedelta64`` operands
+--------------------------------------------------------------
+The modulus (remainder) operator is now supported for two operands
+of type ``np.timedelta64``. The operands may have different units
+and the return value will match the type of the operands.

 There are two Timedelta units ('Y', years and 'M', months) which are treated
 specially, because how much time they represent changes depending
 on when they are used. While a timedelta day unit is equivalent to
