Houdini 17.5.224 Fixed hqueue scheduler errors when scheduling work items. Thu. April 11, 2019
Houdini 17.5.224 The TOPs Deadline scheduler node now works with an empty repository field which allows the user to use the local system default Deadline repository, therefore not requiring to specify the repository or credentials.

Houdini 17.5.224 The Agent Relationship SOP (and the Crowd Solver) now error out if a hierarchy of parented agents contains a cycle. Thu. April 11, 2019

Houdini 17.5.223 Creating an agent primitive through Python (hou.Geometry.createPacked()) now also initializes the 'pointinstancetransform' intrinsic to 1, matching the behaviour of the Agent SOP. Wed. April 10, 2019
Houdini 17.5.223 For the TOP Partition by Bounds node, added bounds and source prefixes to the parm names for the two sets of geometry import parms for improved usability. Wed. April 10, 2019
Houdini 17.5.223 For the TOP Partition by Bounds node, added bounds and source prefixes to the parm names for the two sets of geometry import parms for improved usability. Note that this breaks compatibility.
