Fixed a bug in the Houdini embedded help browser where the browser's zoom factor resetted back to 1 whenever loading a new page.

Renamed RBD Car FollowPath SOP's "Wheel Spin" parameter to "Wheel Spin Scale" for clarity.

Added an option on the Edit Prototypes LOP to not author any composition arc on the selected prim(s). This lets you use this node to create a class prim structure at the destination of an existing inherit arc.

Attempt to improve the performance of the LOP viewport when interacting with handles.

Fixed a bug in motion paths on Abstract Controls that cause the entire path to be drawn, ignoring the values of the "Limit Frames" options.

Fixed a potential crash in the viewport when displaying an agent shape which contained packed primitives with a boneCapture attribute inside the packed geometry.

Add a name alias for the Attribute Adjust Tags for Attribute Adjust Array. In order to make it for the use case of tagging more discoverable in the tab menu.

Fixed a bug where shading normals erroneously used pre-displace normals for motion segments when a mesh has displacement shader and rendered with deformation blur. This bug was introduced in 20.5.305.

Fixed a "No active drawable selector available" python error in the Curve state when attempting to do a selection through the select icon on the left side of the viewport while in the curve state.

Changed default behavior of the Bright COP to leave the alpha channel untouched.

XPU: Fixed a bug in expanding a custom MaterialX node

Fixed a python error in the point weld state when attempting to weld to a point in a different node's geometry.

Fixed a potential crash when using the opexclude command for an operator which had not been loaded yet.

Fixed a potential crash when using the opexclude command for an operator which had not been loaded yet.

Fix a bug that broke in some cases variable reassignments in for loops and conditional blocks in apex script

Add print() and warning() functions and the option to use raise error() to APEX script based on the Log callback. Add a log viewer button to the APEX Script node to improve debugging.

Fix bug where geometry in LOPs view is removed from viewport after finishing incremental updates, in some cases

Fixed a bug in the Agent SOP where the "Use Pivot from First Frame" parameter was incorrectly visible in the FBX import mode. This parameter only affects the Character Rig input mode.

Added a "Log" callback to APEX and added an "APEX" source in the Log Viewer. This callback can be used to print error messages to the APEX log.

Fixed a bug in the Normal SOP that could cause some edges to be unexpectedly cusped.

Fixed an issue in APEX Script where using an augmented assignment statement inside of a scope block could leave the node unconnected resulting in sorting issues. Also, update geometry foreach loops to allow passing a group string to iterate over a subset of the geometry.

Fixed a class of bugs in APEX Script that could arise when using '_portalias' or graph attributes such as 'graph.nodename' inside or after scope blocks which could result in the scope blocks being unexpectedly disconnected or the spare ports being created with incorrect names. Also fixed a bug in APEX Script where nodes would be positioned incorrectly when using relative positioning metadata to position a node relative to some other node that did not have a fixed position.

Fix an issue in APEX Script where using '_portalias' after a loop or if scope could result in the out-going spare port being created with the incorrect name, and another issue where subnet outputs could be created with the incorrect name if using '_portalias' before the return with a different name than was returned.

Some hydra delegates were expecting the data returned by GetRenderStats() to automatically make it through to the renderered image's metadata. This was the behaviour in H19.5 and earlier. There's now a new setting in UsdRenderers.json which specifies with data from the render stats should be translated verbatim to image metadata. This default to "*" so that if a delegate hasn't set up metadata translation, all of the render stats will be saved as metadata.
