The file browser now inserts <UDIM> for the file digits for UDIM sequences (rather than the older %(UDIM)d). Both forms are still accepted, but only <UDIM> will be generated.

Fixed a bug in the Stage Manager LOP tree view that would make it appear that changes to the variant selection of a duplicated row would affect all duplicates of that row.

Fixed assert for invalid light shape being triggered for the light handle.

The Distance Along Geometry SOP, Distance from Geometry SOP, and Distance from Target SOP now have an option to set the mask's radius from the maximum computed distance.

Fixed a potential crash when importing string attributes via the SOP Import LOP.

Added light LOP viewer state with light placement modes.

Fixed a bug with the tie-view-to-camera toggle in the LOPs viewport where it wouldn't take effect if the viewport wasn't looking through a camera already.

When promoting a parameter that has a menu, the '-a' option is now included in the opmenu command to preserve separators from the source menu.

Added the ability to ignore incoming transformations on Input Geometry nodes.

Fixed a bug in the Vellum Solver's String constraints that could lead to NANs and stalled simulations, usually when in use with the OpenCL CPU driver.

HDA Processor: the option to save a debug HIP file will now additionally work in the event that the work item was successful (previously it would only save the debug HIP file if there was an error).

The menus for the 'Attributes' and 'Set Default Values' parameters on the SOP Import LOP now include 'bounds', 'transform', and 'visibility'. These tokens can be used to control whether e.g. extents are authored or are time-dependent.

Fixed bug that could cause Houdini to crash when rendering with a USD ROP in the case where a LOP node was fed into the first and second inputs of a Reference LOP. Fixed the generation of USD in this case as well by ensuring that attempts to write multiple different layers to the same location on disk now automatically generate unique file paths for each layer.

Fix viewport performance problems for animated geometry inside SOPnet manager nodes.

When saving a hip file, we now open the file chooser again if the user chooses not to overwrite an existing file.

Added new HAPI_SetNodeDisplay and HAPI_GetPDGGraphContextId. Updated PDG section in HAPI documentation about PDG cooking, events, and added code samples.

Fixed disappearing instances in the scene graph view if only an instanced prim's transform changed and not the instancer's transforms.

Added strict value comparison modes to the Volume Bound SOP.

HDA Processor will attach attributes in both onGenerate and onPrepareTask now. This ensures that any attributes produced as a result of an upstream node cooking can properly be synced to any HDA Processor attributes that use that upstream attribute.

Sphere lights in the scene graph view are no longer considered single-sided by default.

Fix some cases where the optransform() and originoffset() would evaluate always evaluate as being time dependent.

Setting the viewport pivot will now restart the renderers in LOPs.

The pivot is no longer at the camera origin when the view is locked to a camera in LOPs and the rotate begins over empty space.

Fixed viewport crash in LOPs if a volume changed from a VDB volume to a native volume (or vice versa).

Duplicate shape bindings are now ignored when loading or creating a layer. This scenario previously could result in a variety of display issues in the viewport.
