    • Unboxing a groom operator to extract its constituent operators
    • Groom operator, containing multiple internal operators with ability to expose custom parameters
  • Graft grooms (easy point and click creation of complete grooms on any character model)
    • Built-in eyebrow and hair graft grooms
    • Ability to create new grooms directly within Ornatrix
  • Performance improvements
    • Switched to Embree 3, significantly improving performance in many places
    • Improved hair display performance
    • Using SIMD optimizations to further improve performance
  • Surface Comb operator
    • Allow per-sink rotation adjustments
    • Added "flow" per-sink parameter
    • Channel export
    • Added an option to export sink groups to channel data
    • Exposed sink length setting to the MEL command
    • Added an option to set sink data values based on an absolute length
    • Dim strand channel controls in Surface Comb when not used
  • Hair from Guides
    • Added "Hidden Guide Behavior" option for Hair from Guides (don't generate hair for hidden guides)
    • Parting Tool avoids object selection when in Edit mode if there are no parting planes
    • Multiple distributions maps to allow procedural density map blending
    • Guides from Hair distribution respects distribution map and channel
  • Clumping
    • Added option to set strand groups based on clump ownership
    • "Ground Displaced Roots" option
    • Added an option to exclude already clumped strands from the selection
    • Added Multiplier map support to the Clump Size parameter
  • Normalize operator
    • "By group" option separating its application by strand groups
    • Added a ramp curve
  • Edit Guides operator
    • Allow to move only the roots of strands
    • Allow the Create brush to add strands per-vertex and per-polygon face
    • Preserve strand selection from brush to Control Point/Strand mode
    • Added mirroring support to the Draw tool
    • Update current Attribute Editor channel value based on selection
    • Comb by group options
    • Collision detection during combing options
    • Specify how selection changes when guides are planted
    • Planted guides are interpolated between all selected existing strands (previously only the nearest strand was used)
  • Curl operator
    • Magnitude and Phase randomness for Curl
    • Add range values for Noise Scale parameter
  • Filter operator
    • Added Channel and Map parameters to control random fraction to Filter operator
  • Ground Strands operator
    • Added mesh evaluation at specified time when grounding
  • Arnold render
    • Completed work on Arnold procedural
    • Deploy Arnold extension for both MtoA 4 and 5 in Maya 2019+
  • Baked hair
    • Operator baking now supports baking strand widths
    • Implemented full-stack import with BakedHairNode
  • Animation cache operator
    • Ability to key-frame animation
  • Automatic change tracking of select operators
  • Using Texture Coordinate method for calculating vertex tangents (improved hair smoothness/consistency across surface)
  • Using UV-based vertex tangents by default
  • Switch vertex tangents to use Texture Coordinate generation method by default
  • Using geodesic distance by default to calculate strand group blending effect
  • Added .oxg.zip groom analogs of existing .oxgroom files
  • Maya 2023 support
  • Updated icons
  • Marking/context menus
  • Add "Use Procedural Meshes" option to USD groom export
  • Updated VrayOxHairMaya to work with VRay 5 SDK
