Fixed a bug where cooking a TOP network for the first time would flag the current scene file as modified, when at least one node in the TOP network had a non-default scheduler override.

The attribute wrangle and volume wrangle SOP's snippet cache is no longer reset on changing binding names; this in particular speeds up the attribute paint SOP with many layers.

Fixed a bug where rayimport() call for smooth normal (and subsequently N AOV) on non-poly mesh would output in incorrect space. This also addresses shading artifacts on curves and point meshes under "Simplified Shading" mode.

Prevent crash in PolyBevel-3.0 SOP that occurs when input has vertex attributes of type texture coorindate that are not of size 3.

Improved IPR interactivity under variance convergence mode with area/dome lights.

The video export dialog has been updated.

• The encoding process is now aware of OpenColorIO colorspaces
• A progress bar is now shown while exporting

If a MaterialX-based shader does not have bind export for nested dielectrics IOR ('ndior'), use IOR value of the first transmissive dielectrics BSDF declared in the shader.

In the dopesheet, switching between Region and Select tools keeps the existing selection(s).

Fixed a bug that could result in a crash after an item is evicted from the Alembic archive cache.

Add Channels > Enable/Disable Channel options to the parameter RMB menu that enable/disable the corresponding animation channel(s).

Many bugfixes for the animation graph editor.

• Fixed a bug where disabled segments still visually appeared to be enabled.
• Fixed a bug where selecting value handes was inconsistent.
• Fixed a bug where moving a key horizontally could result in the wrong key being highlighted.
• Fixed ctrl+lmb dragging to remove selection not working.
• Fixed a bug where deselecting a value handle could make it render incorrectly.
• Minor performance improvements.

Updated UE plugin's Curve input UI to match new Geometry and World input UI, added curve point selection controls.

When saving .usd files to disk, work around what seems to be a bug in the USD library which would write these .usd files in ascii format if the destination file is specified as a URL that needs to be resolved by an asset resolver.

Fix another recent Merge LOP behavior change where a "closed" active layer could be modified by nodes following a Merge LOP in "Flatten Into First Input's Active Layer" mode.

Added Karma Material Properties VOP.

Added Karma AOV 2.0 VOP.

Fix another recent Merge LOP behavior change where a "closed" active layer could be modified by nodes following a Merge LOP in "Flatten Into First Input's Active Layer" mode.

Fixed a bug in the Merge LOP that could appear when using "Flatten Into First Input's Active Layer" mode with only a single input connected, and where the input node produced an empty active layer. Also fixed a crash that could occur if the Merge LOP had no inputs connected.
