Fixed an issue where the most recent Houdini GL selection outline would be drawn over the Karma selection outline after switching renderers.

Added hou.ChannelPrim object for managing channel primitives through the hom api. Also added createChannelPrim method to hou.Geometry for creating new channel primitives.

Fixed a threading bug where nested instances 2 levels deep (or deeper) sometimes failed to render.

Added an option to the AttribFromParms SOP to create Channel Primitives from animated parameters.

Fixed a bug where attempting to home all graphs in the animation editor would not update the screen properly

Fixed an issue in the Bend SOP that could result in inaccuracies when the bend amount is very close to 0 due to floating point issues.

Dragging and dropping nodes into USD Primitives parameters will now do nothing if the node is not a LOP node. If it is a LOP node, it will set the parameter to the "last modified paths" of the dropped node.

The Log Viewer has a new logging type for performance monitor events.

Improved performance monitor tracking of LOP operations, breaking down cook time into more specific tasks like USD composition.

Prevent a crash in the Volume LOP when it points to a BGEO file without a name attribute.

Scene graph tree collections subpane now shows collection namespaces as "folders", and all operations can be performed on a whole branch, to apply the operation to all collections under the branch. Also, a new toggle allows the hierarchy to be "flipped" so that collection names are the root of the hierarchy, and prims are the leaf nodes. This view is useful if you have collections with the same name defined on many separate prims in the scene.

Prevent crash when exiting Houdini with a LOPs viewer set to quad viewports with one viewport rendering with a non-Houdini GL renderer.

Added support for shift-clicking in the Select Primitives window to expand or collapse all descendents recursively.

Fixed a bug that caused the "hemax_material" and "hemax_node_name" attributes to not be marshalled for some modifier HDAs.
