Unhide several apex subgraphs: GetRig, UpdateRig, AddControlAction, AddControlGroup AddControlGroupPrimary, AddConfigControl and add the according documentation for the given subgraphs

Fixed a potential crash when updating Karma Physical Sky map while HoudiniVK is the active renderer

Clarified the behavior of hou.hipFile.name() in its documentation and improved the scene event registration example to make mention of hou.hipFile.addEventCallback() as the method for registering scene callbacks. Also mentioned the optional kwargs parameter which gives some additional information for various callbacks.

When auto-tiling with checkpoint files, husk will no longer crash when attempting to stitch a checkpoint render product.

Fixed the LOP viewport to show the correct controls for the background viewport renderer when the renderer is set to Houdini VK.

Fixed the LOP viewport to show the correct controls for the background viewport renderer when the renderer is set to Houdini VK.

Fixed a bug in the APEX Animate state which would cause many tool graphs to recompile too frequently. This fixes a bug that was slowing down the ragdoll posing tool prevented it from evaluating correctly.

Fixed a bug in idenoise when ordering of layers for denoising. This may change the Optix denoiser results when denoising multiple AOVs.

Coordsys-based camera projections now work properly in Karma when motion blur is disabled.

Fixed a crash caused by deleting a track in Motion Mixer.

Unified the values of hou.hipFile.name() and hou.hipFile.path() during scene callbacks and 456.py scripts. hou.hipFile.name() should now report the hip file which is loading (not the previous hip file). This restores the behavior which was present in H20.5.

Fixed a bug which may cause a stale "old_hip_file" value to be reported in the kwargs of scene event callback when hou.hipFile.save() is called without a filename.

Fixed a bug causing $HIP, $HIPFILE, and $HIPNAME to not properly update when calling hou.hipFile.saveAndIncrementFileName() during the first name bump (e.g. name.hip -> name1.hip).

Fixed a bug introduced in 21.0.548 that would cause render delegates to be created twice in rapid succession.

Fixed an issue where PCG nodes would not update the number of inputs when an HDA changes in Session Sync.

Fix erroneous cook error in Joint Deform and Bone Deform SOP nodes when the input geometry's position attribute is in 64-bit precision, or if a deforming attribute's precision changes on the next cook.

Fixed a crash when using the Noise<Float,Float> apex node.

Fixed a bug where selections on primitive instances would continue displaying after being cleared

Fixed a bug in the RBD Bullet Solver SOP's constraint breaking "At Frame" which would ignore the specified constraint names.

Add an option to tabbed multiparms and ramps that allows them to receive UI-only changes to their parameter callbacks.

Fixed a bug when stitching deep images that had a data window that included overscan or cropped data. This also affected the itilestitch command line tool.

Fix the scene graph layers pane to resolve layers using the current stage's asset resolver context, so the resolved layers being displayed will match the layers resolved on the stage.

Muscle Tension Lines Activate SOP viewer state improvements.

• Line ID text display matches selection highlighting more closely.
• Better handling of Line ID text positioning to reduce overlaps.
• Parameters added to control Line ID text font size and random offset.
• Keyboard shortcut added to toggle line colour between activation and ID.
• Group list widget size no longer resets when entering the state.
• Group list widget colour display is off by default.

Fixed the "Import SOP Nodes" button on the APEX Graph SOP. It now properly sets up connections between the imported SOP verbs.
