+Overview of Release 3.2
+=======================

+
+New Features
+------------
+
+Face-Varying Stencil Evaluation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Face-Varying primvar values may now be refined using stencil tables.
+
+The stencil table for a face-varying channel is created by specifying the desired fvarChannel and setting
+the Far::StencilTableFactory::Option interpolationMode to INTERPOLATE_FACE_VARYING when creating the stencil table.
+
+1st and 2nd Derivative Evaluation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The Osd Evaluator API has been extended to support 1st derivative and 2nd partial derivative evaluation for stencils and patches.
+

+| 1st Derivative Surface Normal                      | 2nd Derivative Surface Curvature                     |

+
+On the left is an example of computing a surface normal at each point using the evaluated 1st derivatives,
+while on the right is an example of computing surface curvature at each point using the evaluated 2nd partial derivatives.
+
+Smooth Corner Patch
+~~~~~~~~~~~~~~~~~~~
+
+An option has been added to disable the legacy behavior of generating a sharp-corner patch at a smooth corner.
+Corners which are actually sharp will continue to generate sharp-corner patches.
+
+The differences between the two methods is most apparent at low-levels of feature isolation.
+
+This feature is controlled by the generateLegacySharpCornerPatches option added to Far::PatchTableFactory::Options.
