Improved FBX import performance when processing string attributes.

Muscle Properties Otis and Muscle Constraint Properties Otis SOPs now update muscle highlighting in the viewport as soon as a new multiparm tab is selected. The group and attribute list size is no longer hardcoded by the viewer state for these two nodes.

The Wedge TOP now supports changing how numeric wedge values are applied to the target node. Previously the wedge would always set the target parameter to an @attrib reference expression, however it's now possible to configure the node to apply values directly.

Fixed documentation for the HOUDINI_DEFAULT_LOG_SOURCES environment variable which wsa giving incorrect information about its default value.

.usdnc should show up in File choosers for USD files, allowing selection of apprentice files.

Fixed a bug in karma CPU where LPE AOVs with expressions ending with 'O' (e.g. emission) that exclude certain LPE tag using `^` metacharacter would erroneously exclude object without any LPE tags.

Fixed an issue on Windows where upgrading hserver would often cause a reboot request.

Have Karma AOV VOP author attributes by the same names as Render Var LOP.

Fixed a bug in 'hitN_facing' ray import where normals facing away from viewer at grazing angles produce bad results.

Fixed issue where filtering in the Scene Graph Details could cause Houdini to hang/crash in certain circumstances.

Added a Render Gallery setting to control whether the LOP Network is captured when taking a snapshot. The default remains true, keeping the pre-control behaviour.

Fixed issue where filtering in the Scene Graph Details could cause Houdini to hang/crash in certain circumstances.

Fixed OpenPBR Surface loading in Edit Material Network LOP.

Fixed an issue where ramp paramters could crash inside PCG nodes.

The Fetch LOP can now act like a Begin Context Option Block node, removing entries in the context option block stack, and applying a layer break. It can also specify which output of the source LOP node to fetch.

Add experimental .hipmin scene file which omits much of the compatibility features that allow .hip files to be opened safely by differing versions of Houdini with different HDAs installed. Requires that HOUDINI_EXPERIMENTAL_MINIMAL_SAVE be set to 1 to enable this feature. .hipmin files must be loaded by a houdini session essentially identical to the one they were saved by.

When saving a USD stage with a ROP, set the USD asset resolver context from the stage being saved so layer save paths are resolved correctly. Also, when saving volume files brought in from SOPs, or an image file from COPs, we now explicitly resolve the specified save file path which is most likely to give us a disk file path to which the VDB/BGEO/EXR can be successfully written.

Fixed a bug where updates to pinned curves in the viewport would display incorrectly after attributes are updates

Fixed a regression in the UV Texture SOP when using a camera projection.

The gnomon on dark viewport backgrounds is again desaturated as it was meant to be.
