Make sure VOP subnets respect TAB menu filtering of the parent manager.

Fixed bugs with undoing exclusions of take data from the take list pane.

Fixed an undo ordering issue when undoing removal of node flags from a take.

Added hou.Geometry.isReadOnly() method that will return True if the geometry is read-only.

Fixed FBX import regression introduced in 18.0.553 where child nodes of ths scene root that used hierarchical inheritance stopped importing correctly.

Fixed a potential bug in path delocalization when an output file would container __PDG_DIR__ incorrectly.

Fixed a bug where python script jobs running on Deadline would fail when using pdgcmd RPCs

Fix crash when loading FBX files for KineFX or agents that do not have an explicit frame rate set.

Increased tolerance for detecting 2 input vectors being co-linear in makebasis() vex function. This addresses potential artifacts in direct refractions in mantra when using cone or phong BSDF.

primuvconvert() VEX functions now support integer-based input geometry selection.

The Copy and Transform SOP's re-select action button should now work.

POP Group now has a descriptive parameter for its group.

Volume Rasterize Attributes SOP now has dropdown menus for easy attribute selection.

The .ply conversion code will no longer attempt to create integer attributes from groups - this did not work in any case, and could have caused name collisions. Instead groups should be explicitly converted to integer attributes prior to export if they are to be round-tripped through .ply.

The deprecation link for the gas disturbfield cl now points to the 2.0 version of gasdisturb.

Fixed a bug with turbulence visualization on the pyro solver SOP.

Fixed a crash in Sop Merge Field that occurred when the specified DOP mask was not a scalar field.

Fixed a bug with the Scalar Field Visualization DOP that produced incorrect results when smoke was remapped.

Fixed a bug in the vertex() and prim() hscript expressions that could result in loss of precision when reading large integer values from attributes.

Fixed a crash in the Geometry Import TOP that could occur when canceling a cook mid way through work item generation.

Added support for a file-based Tractor scheduler login. $PDG_TRACTOR_PASSWORD_FILE can be set to the path to a text file containing the base64-encoded password.

The post_outputInstance SOHO hook has been re-ordered so that it occurs before the ray_end() statement. This allows the post_outputInstance hook to add data to the instance while it's still in scope.

The Agent SOP now allows importing agents from a non-animated USD skeleton.

Added an 'Unsaved HIP file' confirmation dialog to the submit- graph-as-job TOP scheduler workflow.

Added a batch_size argument to pdgcmd.reportResultData. This is used in the rare case of sending a large number of result paths in one shot back to PDG. It controls the maximum number paths sent per multicall RPC.

Fixed progress reporting for HQueue. The MQ job will no longer affect the overall job progress calculation.
