Fixed a bug where calling the hou.frame() and hou.time() HOM functions remotely through the hrpyc module reported the wrong frame and time respectively.

Added several help examples for Vellum Solver SOP/DOP, and Vellum Rest Blend, Edge Fracture, and Solid Fracture SOPs.

Fixed a bug that could cause the viewport to attempt to change to an invalid state when changing networks.

Added support for passing a custom list of extra arguments to the Python Script TOP node, when the script is being run out-of-process.

Fixed a bug in material stylesheet where "Attribute Binding" override script may aribitrarily fail if the override parameter data types mismatch between targets (or if some parameters are missing entirely). This also addresses broken Cryptomatte layers that use user properties with attribute binding, when there are objects in the scene that do not share the same set of user properties.

Changed from "pdg" to "houdinipdg" for HOUDINI_SCRIPT_LICENSE env var to specify PDG license for hython.

We now switch to the non-volatile select state when a user sets the component type from the object level volatile select state.

Fixed a periodic viewport artifact on AMD GPUs which looked like a sawtoothed black diagonal across the viewport.

Fixed a crash in TOPs when editing parm interfaces or using the parm choose widget on the Wedge TOP.

In the viewport view state, Ctrl+Alt+MMB now pans the camera screen window to support the existing Ctrl+Alt+RMB feature, which does a box crop of the screen.

Fix a bug in the creation of undo blocks when using HOM to change the size of a Network Box or Sticky Note.

The Partition All (partitionall) TOP node has been renamed to Wait for All (waitforall).

Renamed convertEnvMapToAscii to convertEnvMapToUTF8, and fixed case where it was throwing error when trying to encode to utf8.

Renamed the Mantra Render (mantrarender) TOP node to Render IFD (renderifd), and renamed the Mantra Bake TOP tool to Generate IFD.

Rotations specified in degrees that are exactly multiples of 90 degrees are now often handled exactly, e.g. in Transform SOPs, Objects, UV Project SOPs, etc, instead of being subject to roundoff error due to conversion to radians.

Fixed bug where the python code for setting sticky note text generated by the asCode() methods did not properly account for multi-line text.

Error when hou.Node.destroy() is called while the current evaluation node is cooking to prevent crashes due to illegal behaviour. As a temporary measure, the HOUDINI_ERROR_ON_ILLEGAL_NODE_EDITS environment variable can be used to disable this when set to 0. In general, any scene modification while cooking is illegal and more checks will be added in the future as well as removing the ability to disable these checks.

Made several improvements to the edge detail for concrete fracturing in RBD Material Fracture to improve performance and robustness.

Fixed bug where the python code for a data parameter generated by the asCode() methods contained a doubled comma.

Changed the inverted pyramid knobs drawn when a scale handle is in Squash and Stretch mode to diamonds.

Fixed some performance regression applying material style sheets (introduced in 17.0.417).

Fixed a bug where the initial clip time on the Crowd State DOP could be wrapped incorrectly when using a custom loop range for a clip (via Agent Clip Properties), leading to the agent jumping after the initial frame.

The Points From Volume SOP is now compilable.

Fixed crash when Geometry Import is given an invalid SOP path. Fixed Geometry Import not automatically dirtying items in some cases.
