+Release 1.4.1 (2018-02-20)
+==========================
+
+This release is mostly bug-fixes, but a few enhancements have made it in too:
+
+* Added ``curve_left`` and ``curve_right`` parameters to :meth:`Robot.forward`
+  and :meth:`Robot.backward`.(`#306`_ and `#619`_)
+* Fixed :class:`DistanceSensor` returning incorrect readings after a long
+  pause, and added a lock to ensure multiple distance sensors can operate
+  simultaneously in a single project (`#584`_, `#595`_, `#617`_, `#618`_)
+* Added support for phase/enable motor drivers with :class:`PhaseEnableMotor`,
+  :class:`PhaseEnableRobot`, and descendants, thanks to Ian Harcombe!
+  (`#386`_)
+* A variety of other minor enhancements, largely thanks to Andrew Scheller!
+  (`#479`_, `#489`_, `#491`_, `#492`_)
