-Upcoming version (not yet released)
------------------------------------
+Version 2.3.7 (July 20, 2023)
+-----------------------------
 
 General
 ^^^^^^^
 
-- Added primitive collider for sphere-cylinder contacts, previously this pair used the generic convex-convex collider.
-- Added :ref:`joint-actuatorforcerange<body-joint-actuatorforcerange>` for clamping total actuator force at joints and
-  :ref:`sensor-jointactuatorfrc<sensor-jointactuatorfrc>` for measuring total actuation force applied at a joint. The
-  most important use case for joint-level actuator force clamping is to ensure that
-  :ref:`Cartesian actuator<actuator-general-refsite>` forces are realizable by individual motors at the joints.
-  See :ref:`CForceRange` for details.
-- Added an optional ``content_type`` attribute to hfield, texture, and mesh assets. This attribute supports a formatted
-  `Media Type <https://www.iana.org/assignments/media-types/media-types.xhtml>`_ (previously known as MIME type) string
-  used to determine the type of the asset file without resorting to pulling the type from the file extension.
-- Added analytic derivatives for quaternion :ref:`subtraction<mjd_subQuat>` and :ref:`integration<mjd_quatIntegrate>`
-  (rotation with an angular velocity). Derivatives are in the 3D tangent space.
-- Added :ref:`mjv_connector` which has identical functionality to :ref:`mjv_makeConnector`, but with more convenient
-  "from-to" argument parametrization. :ref:`mjv_makeConnector` is now deprecated.
-- Bumped oldest supported MacOS from version 10.12 to 11. MacOS 11 is the oldest version still maintained by Apple.
