New:
- Added a reversible Isolate Selected toggle to Edit Guides, which can be undone; the old permanent behavior is now called Hide Unselected
- Adopt External Guides no longer requires a separate reference guides object
- Added a Match Strand Groups option to Adopt External Guides, so each hair strand follows only the control guides of its own strand group
- Added a Concatenate Strand Groups option to Merge, which renumbers each merged object's strand groups so they cannot collide
- Added even clump distribution with a distribution map
- Reduced groom file size by writing mesh face indices as flat binary arrays

Fixed:
- Fixed a crash when moving a clump knot's position in the viewport
- Fixed a selected regular Surface Comb sink having no Move, Scale or Rotate gizmo
- Fixed importing a groom with an object selected producing no hair
- Fixed per-clump and pattern knot parameters not taking effect until the groom was reloaded
- Fixed the Groom operator producing no hair for a groom whose base object is a procedural Sphere
- Fixed hair spinning around when the base surface is rotated
- Fixed a Mesh From Strands crash with Conform to Surface when the distribution mesh is carried only by the hair
- Fixed groom script parameter values being lost on scene save and reload
- Fixed merged ungrounded strands being moved to the first distribution mesh face
- Fixed merged strands grounded to a different distribution mesh being re-planted
- Fixed merge target hair strands being moved to the first distribution mesh face
- Fixed dynamic grounding not working correctly in all situations, including when no source surface is set
- Fixed a clumping error when UV space is used with a mapping channel the hair does not have
- Fixed guides hidden in Edit Guides reappearing on the next evaluation
- Fixed guides created by the Create brush not inheriting the strand group of the closest guide
