 Upcoming version (not yet released)
 -----------------------------------
 
+Significant new features
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+- Actuators and sensors now support arbitrary delays via history buffers, and sensors values can be computed at
+  intervals larger than the simulation timestep. Using a delay or interval introduces a new ``mjData.history`` variable
+  to the :ref:`Physics state<siPhysicsState>`. See :ref:`Delays<CDelay>` for details.

+- Added new :ref:`flexvert<equality-flexvert>` equality constraints that enable cloth simulations with coarser meshes.
+  This adds a new option ``vert`` to flexcomp edge :ref:`equality<flexcomp-edge-equality>` and the new equality type
+  :ref:`flexvert<equality-flexvert>`.

+- Rangefinder sensors can now be attached to a camera using the :ref:`ragefinder/camera<sensor-rangefinder-camera>`
+  attribute. In this case, the sensor will cast multiple ray, one for each pixel.
+- :ref:`Rangefinders<sensor-rangefinder>` can now report various kinds of information besides ray distances,
+  including surface normals.

 - Camera frustum visualization is now triggered by setting :ref:`resolution<body-camera-resolution>` to values larger
   than 1. Relatedly, frustum visualization also works for :ref:`orthographic<body-camera-projection>` cameras.
-- Rangefinder sensors can now be attached to a camera using the :ref:`ragefinder/camera<sensor-rangefinder-camera>`
-  attribute. In this case, the sensor will cast multiple ray, one for each pixel.
-- Rangefinder sensors can now now report various kinds of information besides ray distances, including surface normals.
   See :ref:`rangefinder<sensor-rangefinder>` for details.
 - Cameras now have an :ref:`output<body-camera-output>` attribute, parsed into the ``mjModel.cam_output`` bitfield.
   Unused by the renderer, it serves as a convenient location to store a camera's supported output types.
