The Switch TOP now has a parameter to explicitly control how out of bounds switch indices are handled. The default behavior is to display a warning on the node as before, but it's now also possible to ignore out of bounds indices or treat them as errors.

Fixed an issue where Houdini could crash when calling some lopcamutils functions from multiple threads at the same time.

Bumped up the libarchive library that Houdini ships with to version 3.6.2.

Fixed an issue with PDG's handling of disabled TOP parameters. Parameters inside of a locked TOP asset will no longer be flagged as disabled unless their parm conditional expression indicates that they should be. Prior to this change, parameters in a locked TOP asset would always be treated as disabled by PDG. This was affecting PDG attribute control flow, since disabled parameters won't affect the static vs. dynamic state of a PDG node.

Prevents a crash that can occur in UVFlatten 3.0 SOP that can occur when Axis-Aligned Vertex Groups are specified with invalid conditions.

Various fixes for the animation editor.

• Fixed values and time marks not showing numbers when selected.
• Fixed time marks being cropped after pressing H to home the viewport.
• Fixed a crash that would occur if all keys of a channel are deleted.

The collection tree pane will now find and show collections defined on instance proxy primitives.

The Mac OS version of Houdini now properly handles spaces in installation path names when compiling OpenCL code for the Vellum and Pyro solvers, among others.

The Graph Color SOP is now faster and uses less GPU memory when in Primitive mode, which also speeds up graph coloring in the Vellum Solver.

Fixed a bug in the work item file deletion dialog which was causing the Cancel button to consider all files to be selected, rather than dismissing the dialog without making changes to the node.

Fixed a bug in the Crowd Source SOP where randomizing the initial state only supported pattern matching against clips from the first input agent, ignoring the effects of the Randomize Agent Primitive option.

Husk will now consistently provide upper case channel names for OpenEXR files. There's a new property that husk looks for on Render Var primitives named driver:parameters:aov:channel_lower_rgb which will cause the channel names to be created with lower case.

Fixed a bug where changing purpose attribute had no effect in IPR update until render restart.

Improved the performance of the Merge LOP when changing upstream nodes.
