Changes to the split by attribute feature on partitioner nodes:

• When splitting by attribute with a partitioner TOP, it is now possible tospecify a default attribute value for work items that are missing thesplit attribute.

• Partitioner nodes that are configured to split by attribute, with allinput work items missing the specified attribute, will now still havetheir onPartition callback invoked when the Split Missing parameter isset to "Handle In Python Code".

Add support for reading the new keystring format from license files.

Fixed a bug where "Use Menu Item as Token Value" wasn't copied.

Better support for the 'sidefx::shader_parmname' parm tag when creating input/output during USD shader translation.

Fixed an issue where "Show Images" option in the file chooser was ignored. Also changed hou.ui.selectFile's image_chooser argument such that when the argument is specified, the user preferences will be ignored.

Added missing hou.confirmType.SaveEmbeddedDefinitions enum value for completeness and fixed bugs with the use of hou.confirmType enum that could cause dialogs opened by hou.ui.displayConfirmation() to set the wrong suppression preference when suppressed by the user.

Fixed a bug in the network error handling when Deadline jobs fail to contact the MQ.

The LOP viewer will now follow the Scene Graph Tree selection and view masks when inside LOP subnets.

Fixed potential crash when running an opparm command that added a missing multiparm instance followed by a chlock command, which is something that can occur when changing a node's type.

Hardened some GL code to avoid viewport crashes on MacOS.

Forcing the JOB variable to be always global.

Fixed bug where growing/shrinking point selections did not work on curve primitives.

Added support for hemax_node_name_output as a primitive attribute, which can be used to override the 3ds Max node name for geometry objects created from packed primitives.

Fixed a bug that could cause HDA Processor to break when used within a blackboxed HDA.

Fixed a bug where the peak usage of a license could be slightly higher then it should be in some cases.

Fixed a bug where changing the "TOP Scheduler Override" parm would not take effect on the next cook.

Fixed crash when doing a flood fill selection in toggle mode with no existing selection.

VDB to Spheres SOP will no longer revert to spacing of 0.1 when in world space mode.

Fixed a bug in Group Promote when promoting edge groups to vertex groups with Include Only Element Entirely Contained in Original Group.

Fixed a bug where interrupting a render that was initiated from Python code caused a KeyboardInterrupt exception to be raised when Houdini executed subsequent, but unrelated, Python code. The bug manifested itself as random failures in Houdini from Python error stack traces appearing in the Network View to Python error dialogs popping up.

Fixed issues that prevented custom HDAs from being used as a crowd trigger (e.g. as the input to a trigger logic or transition DOP). Any node that has a 'triggerattrib' parameter can now be used as a trigger (similar to 'streamname' for POP streams).

The USD ROP, USD Render ROP, and Karma LOP now all have a parameter to control whether layers authored above layer break LOPs should be written to the USD files on disk or not. Default behaviors remain unchanged, with the USD ROP stripping layers above layer breaks, and the USD Render ROP and Karma LOP saving layers above layer breaks by default.

Added IsSessionActive method to the MaxScript API.

The camera LOP has a new parameter that can hide the camera from the viewport camera menu (in cases where the camera is for utility purposes, not meant for looking through).
