Added a Squash and Stretch mode to scale handles which attempts to preserve bounding box volume on non-uniform scale operations.

Moved the custom index logic from the partition by index TOP node to the partition by attribute node, since the indexing logic is drive by attribute values. Along with this, a new Sort TOP has been added which can be used to reorder work items based on one or more attribute values.

Added ability to undo cuts/pastes in the Pose Library.

PDG: CSV Output node now creates folder path for output file if it doesn't exist.

The Cloud Light SOP node is now compilable.

The Volume Arrival Time SOP node has been enhanced:

• It is now both compilable
• The "Speed" parameter now works as expected by only creating volumes forthe group of primitives specified.
• Naming for multiple output volumes are now supported by using a list ofspace separated list of names for naming each volume individually. If yourequire to name an output with space, please enclose such names withindouble-quotes.

Background enviroment maps in the viewport now respect the quality option in the Background tab of the display options.

Fixes issue when switching which sesinetd hserver points to causes programs not to be able to checkout licenses.

Fix Cloud Light SOP for multiple input volumes. It now creates a set of Ce.[xyz] fields for each input volume.

Unity plugin: Instanced objects now have their transform combined with their source prefab transform. Originally the point transform overrode existing Unity's transform.

Fixed HEU_GeoSync creating extraneous prefab instances due to importing then loading the asset. Removed the import, and kept just the load. Fixed HEU_GeoSync instances properly applying the point transform with the source prefab's transform. Fixed work item tallying for PDG Asset Link interface.

Fixed "Update Input Landscape Data" not working properly with object merge inputs.

Fixed a bug in the Edit SOP that incorrectly disabled display of the cooked selection when dragging away from the selection with secure selection enabled.

The Facet SOP now has a Group Type parameter, giving the ability to specify a numeric point group, making it a replacement for the Unique Points option on the old Fuse SOP.

Fixed the density attribute painting button on the Hair Generate object.

Unity plugin: Added support for part instancers and point attribute instancing for HEU_GeoSync and the threaded geometry loader. This means that prefabs and assets in Unity can be instanced by setting their paths on point attributes.

Added GL tags to a few more parameters in the Principled shader that were missing them, improving the envmap and coat looks and adding support for reflect textures.

Fixed a viewport bug with SOP guides sometimes refusing to update.

Agent base discs now properly display when the viewport is in Z-up mode.

Fix for HAPI_DirtyPDGNode to only dirty the TOP node specified, unless its a TOP_Network in which case it dirties all the TOP nodes within.

Unity plugin: Lots of UI improvements and some bug fixes to the PDG Asset Link: More polished interface, added work items tally, showing work items tally for entire asset, as well as individual top nodes, and progress ratio.

The BlendShapes SOP is now faster than before when no blend weights have become zero or become non-zero since the previous cook if the Cache Input Deltas option is on.

Fixed a crash in the Scatter SOP and a few other nodes if all of the input's point positions are NaN. The Scatter SOP now generates no points if the input is all NaN.

Added a preserve original index toggle to the work item expand node, which is used to configure how the expanded items are index. When the toggle is on the items will inherit their index from the original work item, and when its off the index will be set to the item's position within the expanded list.
