Added viewerstate.utils.hotkeyContextForState() and viewerhandle.utils.hotkeyContextForHandle() to make backporting fixes to 19.5 easier.

Fixed "Vector2 to Vector4" VOP's VEX source code to correct variable names.

Fixed group parm in MusclePaint hda so that prim selections made using @muscle_id=muscle syntax are converted to a valid point group internally for the AttributePaint sop inside.

Fixed an issue with running LOP VEX code on more than 5120 elements, where per-element data is being pulled from SOPs.

Added a new "Generae Node (Static)" option the context menu on TOP nodes. This performs the same operation as the "Generate Node" menu entry, however it doesn't trigger any cooks even if the selected node is dynamic. It causes static work items to be generated until the first dynamic node in the chain is reached.

Added a new optional argument to hou.TopNode.generateStaticWorkItems(..) that specifies the list of nodes to generate. When a node list is specified static items are generated for each of the nodes in the list, instead of for the whole graph.

Fixed a bug with unpacking USD geometry where non-array primvars did not have their typeinfo correctly converted to the SOP attribute.

Fixed macOS-only checks in Houdini that failed to detect the Apple GPU on M1 and M2 machines. This resulted in a viewport performance hit for some use cases.

Added a multigrid solve to the Point Cloud Surface SOP to improve the global surface.

Extract Instances LOP now has an option to deactivate point instancers when all instances are extracted. Point Instancer array primvars with an elementsize of 0, and optionally unauthored elementsize, are inherited as scalar primvars.

Fixed a bug in the Cone Twist Constraint DOP where the guide geometry for twist limits could be incorrectly displayed.

In animation editor Dopesheet, showing and hiding the "All Displayed Channels" row now properly moves the currently active selections up or down so they remain valid.

In animation editor Dopesheet, pasting into the "All Displayed Channels" row from a copy that did not include all displayed channels is now disallowed and gives a warning.

Fixed accidental change to Merge LOP output with no connected inputs.

Added new configuration keys to the HQueue server configuration file, hqserver.ini, for controlling the `waitress` web server component in the HQueue server. Specifically, new `ignore_logging` and `threads` keys are supported under the `[waitress]` section.

'Material Builder' re-labeled to 'VEX Material Builder', to clarify the types of shaders found insde.

Render delegate developers can now put environment variables in the "menulabel" field of their UsdRenderers.json file, and they will be expanded in the render delegate menu in the viewport.
