- Lighting: Fix equiangular clipping in presence of infinite lights
- Lighting: Several fixes related to light selection
- Lighting: Fixed a live render bug where the ramp would render backwards initially if begin > end
- Integrators: A crash in the Path Guiding feature of PxrUnified has been fixed
- BxDFs: Added labels for glass parameters to PxrLayerSurface to match PxrSurface: Shading Tangent, Manifold Walk IOR, and Anisotropy
- BxDFs: Fixed presets in LamaConductor
- OSL: Silenced a debug message that was slowing down regex_search()
- OSL: Improved OSL metadata tokenization to correctly handle <primvar:varname>
- OSL: Fix out-of-bounds vector access when a spline is provided with only a single control point
- Alembic: Fix for incorrect renders that could show up with polygonal input data with normals
- Geometry: Fixed a memory leak for the case of general polygons which also occurred for pretessellated subdivision surfaces
- Volumes: indirect visibility of volumes now correctly takes into account scattering events that occur within the volume. Previously indirect visibility was only checked at volume interfaces, which meant that surfaces within volumes that also enclosed the camera could wrongly reflect indirect invisible volumes
- Checkpointing: When using the new variance metric, fixed a problem that prevented resuming from a checkpoint
- Rendering: Fixed an issue that if you edited the shutter value, the framing and sampling unexpectedly changed
- Rendering: Add support for FloatVectorAttribute when setting metadata for EXR output
