Added a temporary workaround to an issue that will cause Houdini to lock up when SessionSync is active and an HDA with a Python Script node is cooked through HAPI. The fix is only activated by enabling the HOUDINI_ENGINE_SESSIONSYNC_EXPERIMENTAL environment variable. When using the workaround, there is a limitation that any Python Script nodes that are cooked cannot spawn additional threads that call into HOM.

Fixed an issue with simple drawable outlines that caused a white outline as well as the custom colored one in certain situations. Also fixed a bug that caused the outline color of the object in the back to be taken when an object was partially covered by another object.

Added a Clean SOP inside the Ocean Foam SOP to handle degenerate geometry at low camera angles that could lead to no foam particles being emitted.

Updated the UV Textures Preview in SOPs viewport, to use new maps.

Fixed a bug where objects with defaultshader (i.e. no material assignment) would ignore 'displayOpacity' primvar in offline renders.

Fixed a number of issues when using the Layout LOP to edit an existing point instancer. This workflow should now behave properly, though as before, if the point instancer is changed upstream, the downstream Layout LOP won't adopt these changes unless you "Reset Changes" to reinitialize the Layout LOP, which loses all work done so far.

The Modify Point Instances LOP can now take instancing attributes to modify instance transforms. i.e: scale, pscale, orient etc...

Fixed an issue where cooked landscapes would be deleted correctly.

Added support for material instances in landscapes.

Fixed an issue where edited landscape layers would be deleted correctly.

Added support for material instances in landscape import.

The USD Schemas for Karma have been renamed.

Karma now reads the primvars:angularVelocities primvar for instance velocity blur.

Improved the performance of the Volume LOP when loading VDB files.

Fixed a bug in the PolyExtrude-2.0 SOP that could result in incorrect extrude direction when extruding edges.

Added a `isPersistent` flag to PDG services that indicates whether or not a service should be saved to disk, and exposed it on the Service Create TOP.

Fixed the LOP Import Camera object to set the correct focal langth, aperture, and other Camera parameter settings when the Primitive Path parameter is using a prim pattern like `%type(Camera)`.

Fixed a bug with fluid sinks not working correctly in a FLIP simulation if full reseeding was not enabled.

Fixed a bug where the PolyCut SOP could produce NaNs when cutting at an attribute crossing if both points of an edge had the exact same value as the cut value.

Fixed an issue with the plugin not handling UV or Cd attributes correctly when the attribute had a tuple size other than 3, which was leading to crashes in the plugin.
