Husk will now consistently provide upper case channel names for OpenEXR files. There's a new property that husk looks for on Render Var primitives named driver:parameters:aov:channel_lower_rgb which will cause the channel names to be created with lower case.

Fixed a bug where changing purpose attribute had no effect in IPR update until render restart.

Improved the performance of the Merge LOP when changing upstream nodes.

Fixed a bug in the animation editor where rapidly moving a keyframe using CTRL+LMB DRAG could make its value change.

When saving out USD files that refer to files inside $HFS, Houdini now converts these full paths to "search paths" by stripping off the $HFS prefix. When starting Houdini, if PXR_AR_DEFAULT_SEARCH_PATH is not set, set it to $HFS so that these search paths resolve as expected.

Prevents a crash that can occur in UVFlatten 3.0 SOP that can occur when Axis-Aligned Vertex Groups are specified with invalid conditions.

Fixed a bug with the pyro shader producing incorrect results with negative density values.

Added Stencil Field support to the SOP Merge Field DOP.

It's now possible to create partitions in a pdg.PartitionHolder using a string name instead of an index. When the partition step is finished, the names of all string-based partitions are sorted and the partitions are assigned an index based on their position with the sorted list.

Added a new mode to the Cone Twist constraint to behave as a soft constraint. This is primarily useful when the motor is enabled, as it allows the target orientation to be followed in a spring-like manner which is not easily achieved with the motor's Max Impulse controls. When enabled, the position and rotation limits also behave as soft constraints, so lower stiffness values can allow the boundaries to behave in a softer manner.

Fixed gplay crash trying to open the geometry info window when there is no geometry.

IMG_File::open()/create() now return a unique ptr.

Add support for logging when we checkout a license seat and checkin a license seat and update the heartbeat message to follow the same pattern.

checkin: IN [licenseid] [seatid] [product] checkout: OUT [licenseid] [seatid] [product] [user@machine] heartbeat: HEARTBEAT [licenseid] [seatid] [product] [pass/fail]

Added a density gravity feature to the Pyro Solver which allows the force of gravity applied to the fluid to be scaled differently based on the density.

Fixed a bug where changing purpose attribute had no effect in IPR update until render restart.

Removed the message "Retrieving information about installed licenses..." from sesictrl.

Added hou.Parm methods to move multi parm instances.

• hou.Parm.moveMultiParmInstances(moves)
• hou.Parm.moveDownMultiParmInstance(inst_index)
• hou.Parm.moveUpMultiParmInstance(inst_index)
