In the Hair Generate SOP, don't recreate skinprim and skinprimuv attributes when in Extrude and Blend mode. Existing setups may require an additional Guide Skin Attribute Lookup SOP on the guide input.

Introducing a new environment variable ($HOUDINI_LOP_STITCH_DEDUPLICATE_SAMPLES) to control whether or not to avoid authoring duplicated time samples during layer stitching. The default for this variable is `0`, which disables the code which previously always ran.

Merging geometry where detail attributes conflict will now preserve the first detail attribute consistently. Previously, this was the case for float / integer attributes; but strings / dictionaries / arrays behaved differently. They are now consistent in keeping the first.

On Windows, the value of the TEMP environment variable is no longer modified to be the same value as HOUDINI_TEMP_DIR on Houdini start up.

MaterialX height-to-normal node now outputs in tangent-space, which aligns with the 1.38 specification (previously the normal was output in world-space)

How the Ray SOP's jittered rays are computed has changed. The new method allows the sop to multithread in this case, but will thus generate different results.

The Python SOP now has a 'Maintain State' toggle which controls whether the node's Python context is cleared after each cook or not. The effective previous behaviour was not to clear the context, but the new default behaviour is to clear the context. For the previous behaviour, simply enable the toggle.
