Fixed a bug that would cause Houdini to always use an HDA's definition stored on file even if it had been overwritten with an HDA loaded from memory.

Fixed a Windows-only bug where tablet event information, such as pressure and tilt, was lost if Windows Ink was turned off in the Wacom Tablet Properties.

Added SetHdaSelectionLocked function to the Maxscript API.

Fuse SOP will now properly update when the grid spacing changes and no consolidation is present.

Fixed a bug in the Channel SOP which would prevent it from extracting data from channels into indexed elements of attributes.

Fixed a regression in Animation Layer CHOP when the base layer isn't animated and the weight parameter is. The weights were evaluating at the last time the base layer was cooked. This was causing the animation from weight parameter to be ignored.

Pop Axis Force guide geometry will orient properly now.

Fixed a viewport crash with Alembic when mixed with other primitives in the same detail, and some of those primitives were deleted.

Performance improvements for texture() functions when the filename is a varying value.

Fixed a bug when cloning a geometry HDA that would cause the cloned geometry to be incorrectly offset from the parent dummy object node.

Added the ability to save specific sequences in MPlay with the -s and -S flags, which expect a name from seqls or seqls -f.

Fix FBX import bug at certain frame rates where the channel evaluation results for joints bound to skin deformers at frame 1 may be wrong.

Fixed a bug preventing int8 and int16 attribute data from being copied with HAPI_GetAttributeIntData

Prevent a python exception that could occur in a network editor pane when doing File->New.

Fixed bugs where the cell input field was positioned ever so slightly off when the spreadsheet was resized.

Fixed a viewport crash with packed alembics.

Fix memory leak with intersecting HeightFields.

Modifiers and container nodes for SOP HDAs will now be named according to the HDA name rather than the name of the parent geometry node.

Added 2 new methods to the MaxScript API:

• SetGeometryHdaAutoRecookingEnabled
• SetModifierHdaAutoRecookingEnabled

ROP Mantra Render TOP will now automatically add an HQueue job parm "Tags" set to "single". This ensures that when scheduled with HQueue, only one Mantra job will be run per machine. This is desireable to avoid oversubscribing the CPU resources.

Updated the default value of the Bend SOP's "Up Vector Control" parameter to allow backwards compatibility with the Bend SOP in Houdini 17.5.

Added hou.ParmTuple.evalAsJSONMaps() and hou.ParmTuple.evalAsJSONMapsAtFrame() HOM methods.

Fix invalid Qt stylesheet line.

TOP Fetch will now run hython without the --pdg switch, which means it will no longer take a PilotPDG license over an Engine license.

Deadline tasks will now preserve HOUDINI_PATH when it exists in the Job environment.
