Add HAPI_NODETYPE_COP to the HAPI_NodeType enum, which, for example, allows you to filter for COP nodes using HAPI_ComposeChildNodeList(). Note that HAPI_NODETYPE_COP previously referred to the old compositing nodes, but now refers to modern COP nodes. The old compositing nodes are now HAPI_NODETYPE_COP2. This makes the naming scheme for COP and COP2 consistent with other parts of Houdini.

Changes to a COP networks default resolution will cause interactive renders that reference that COP as a texture to restart.

itoa() will work with 64bit integers in VEX.

Fixed a bug where husk would try to use undefined values for resolution, pixel aspect, or data window property if there are multiple render products and there are products that defines the property while the first product doesn't.

Performance improvements when importing landscapes into Unreal from Houdini. Can be 2x speed up on very large landscapes.

Importing parameters and refreshing existing imported parameters now copies any tags (spare data) from the source parameters. This fixes an issue where we failed to copy button icons and makes importing more consistent with dragging node parameters to copy them.

Added new hou.LopNode.uneditableStage method for use in Python LOPs using the editableLayer approach. Provides read only access to the current state of the USD stage.

XPU: Fixed bug on averaging the shading normal which caused artefacts with non grey weights were used.

Output processors now have a new endSave method which is called after all files have been saved to disk by the ROP node. All output processor methods can also raise exceptions to interrupt the save process and flag an error on the ROP node.

Fixed bug refreshing parameter import blocks where refreshed "Spacer" parameters would output as an unrecognized type in the dialog script and end up being loaded as float parameters.

The `-o` (`--output`) command line argument to husk can now override delegate render product names. So, if there's a single "arnold" productType render product, the `-o` argument will now override the filename as expected.

If there are multiple render products being rendered simultaneously, an override for every render product is needed for this behaviour (otherwise only raster product names are overriddedn, as in earlier versions).

Fixed an issue with shelf edits getting sometimes dropped and reset after updating Houdini to a new daily build.

Fixed an issue where editing level instances could cause a crash after commiting the data if an Houdini Asset Component was present. Ensure level instances do not cook when they are not being edited. Fixed an issue where duplicate mesh components could occur when opening a level instance containing an HDA.

Fixed an issue with Selection Sets in the APEX Animate state where pinned or isolated controls under "All Controls" would not be saved and reloaded when exiting and re-entering the state.

The TOP Geometry SOP node can now be configured to import work itesm from any external TOP network, in addition to the one already embedded in the TOP Geometry.

Added initial version of adaptive quad sizing in Quad Remesh SOP.

Updated main hotkeys documentation to include some info previously only mentioned in the What's New in 20.0.

Fixed issue selecting filenames when using the --frame-list command line option.

Fixed negative scales when leveling controls in the multiik component.

Updated main hotkeys documentation to include some info previously only mentioned in the What's New in 20.0.

Removed the "Pin Root" option from the ragdoll tool's settings, which had some confusing behaviour and could not vary per character. The replacement for this option is to select the root collision shape and turn off the Active toggle in its settings.

Fixed a bug with distance_pointline and distance_pointray VEX functions producing incorrect results with non-normalized direction inputs.
