Fixed a bug in the Scatter 2.0 SOP that prevented detail attributes identified with the "Detail as Detail" parameter from being copied correctly.

The standard output and standard error Log Viewer sources now work on Windows even if HOUDINI_DISABLE_CONSOLE=1.

Fixed shadowmap rendering in the Flipbook ROP.

Fixed a possible core dump in VEX when inferring return types on dict square bracket operators. This line no longer crashes VEX during compiling: removeindex(d@foo["a"][0], "b")

Added Scroll to Current Frame to the Animation Editor with a Shift+F keyboard shortcut.

Fixed a regression introduced in 20.5 related to hou.text.relPath() when the paths have symlinks.

Fixed heighfield shading when a material other than a heightfield material is applied.

Fix a number of issues with decompiling graphs in APEX Script SOP that were causing issues when attempting to decompile the example component graphs.

• Fixed issues decompiling untyped nulls, or geometry for each loops.
• Fixed issues with correctly finding variable names in several cases.
• Fixed issues when name conflicts exist between subnets and variables.
• Fixed issue where underscore suffix was being removed from all namesinstead of just those that are protected keywords.
• Fixed issue decompiling if blocks where a variable reassignment occurs.

Fixed a viewer crash with selections and packed prims.

Fixed a viewer crash when looking through a camera with a foreground image.

Added support for unreal_back_actor_class in curves.

Added support for VEX derivative functions (such as Du, Dv, volume and gradient) on volume primitives.

Added support for unreal_bake_actor_class to curves.

Only fetch editable nodes if edit tools are enabled. Several checkboxes are now disabled, rather than made invisible, if they are not appropriate for the current HDA.

Updated the Ubuntu Dockerfile to use Ubuntu 22.04 and included more required packages.

Fixed an issue with topology mirroring in the Attribute Mirror SOP that would lead to bands of unmirrored elements and unwanted flipping of sidedness. Fixed an issue where the default sidedness would be arbitrary; the source side is now set to the side with the lowest primitive number. Fixed an issue where vertices could be mapped to themselves; their Element Mapping is now set to -1.

Made ML Example more efficient by replacing its internals with a specialized C++ core node.

Fixed an issue in the APEX Animate state where pressing and holding with the mouse on a control without moving the cursor would never select anything. This is now treated as a single click in that location.
