Added an option on the Unpack USD SOP to perform additional iterations of unpacking, or continue unpacking as far as possible. An optional integer attribute can also be added to the geometry to record the nesting level when unpacking point instancers.

The Flop option on the Flip COP is now called Flip Diagonally to be more clear as to its operation.

Fixed issues that could cause volumes inside Packed USD primitives to not be displayed in the viewport.

Fixed a bug in the Unpack USD SOP where unpacking to packed primitives with no traversal produced empty geometry, rather than outputting the original packed prims.

Added an option on the Unpack USD SOP to perform additional iterations of unpacking, or continue unpacking as far as possible. An optional integer attribute can also be added to the geometry to record the nesting level when unpacking point instancers.

Fixed a bug with subnets in Remote TOP Graphs copying input nodes into the subnet, for each Input inside the original subnet. In addition to causing the graph to have an excessive number of nodes, this was also causing unecesarily large .hip file sizes when saving a TOP network with a Remote Graph node in it.

Attribute Fill SOP is now able to work on multiple destination attributes in one node.

Saving Recipes to UNC path on windows appears to be bust

• Fix a bug in hutil.path.resolvePath when handling a UNC path on Windows.

Python States - Binding a Geometry Selector and a Dynamic Handle results in

strange behaviors when hitting 'trs'

• Fix a bug in python states to allow tools to be invoked when a bound selectoris active.
• SOP and LOP states can now invoke tools as expected.

Python HUD Handles - New preference to show/hide HUD handles

• Add new preference (hudh.enabled_state) for enabling and disabling HUD handles.
• HUD Handles are enabled by default.
• All HUDs can be disabled by setting hudh.enabled_state to OFF with theHUD Handle preference dialog. However, HUDs bound to python states cannot.

Package Browser - Update

• Add HOUDINI_SCRIPT_PATH legacy support
• Add new dialog for creating packages and package archives
• Add support for activating and deactivating packages
• Add drag and drop support for loading packages and package archives.
• Add delete package support
• Now unset package environment variables when unloading a package
• Add new documentation

XPU: reduced CPU memory usage from the Optix device

Fixed a crash caused by running the `hou.ui.desktop()` HOM function in the Python Shell.

Enable the option "Use #import for Prequel Code" on OpenCL nodes in the Sample COP.

Fixed a bug where fallback value wasn't being applied when using Mtlx USD Primvar Reader VOP.

Fix potential issue in Python script that may block saving tools to files.

Added new environment variables HOUDINI_DEFAULT_LOG_FILE and HOUDINI_DEFAULT_LOG_FILE_SOURCES to cause Houdini to send logs to a file on disk. Especially useful for debugging crashes or issues during Houdini startup before the log viewer pane is accessible.

Fixed a bug with the Detail from Single Mode method on the Attrib from Parms SOP where the node would not recook when the spare parameter list on the target node was updated.

Fix an issue with primitive snapping to curves in the Curve state that could result in snapped positions being slightly off of the snapped primitive.

Added a new COPs sample compositing setup to the Background Plate LOP's quick setup menu.

XPU: fixed an Optix device crash that could happen when XPU is used with COPs

Fixed a bug in Path Deform and Chain SOPs on curves with points with multiple vertices that could cause incorrect results.

Fixed the filtering of attribs and groups on sim points on the RBD IO SOP.

Fixed a bug with subnets in Remote TOP Graphs copying input nodes into the subnet, for each Input inside the original subnet. In addition to causing the graph to have an excessive number of nodes, this was also causing unecesarily large .hip file sizes when saving a TOP network with a Remote Graph node in it.
