New:
- Copy version button in the About dialog
- Edit Guides: Isolate Selected is a reversible visibility layer that nests, with a Ctrl+Alt+Q shortcut
- Refresh button under the graft groom list, rescanning the grooms directory
- Groom operator has a graft surface subdivision level, so graft groom hair follows a curved target mesh
- Recompute Surface Positions option in Multiplier, so copies moved by Spread or Shift get their own surface position instead of keeping the source strand's
- Grooms saved with a distribution mesh keep its hard edges
- Guides From Mesh and Hair From Guides store their Remember Roots state in the groom, so it survives a groom export
- Faster hair generation with Even distribution
- Generate Strand Data expressions are now evaluated by an in-house engine, and noise based expressions produce a different pattern than before
- Alembic import loads unprefixed float and vector geometry parameters as strand channels

Fixed:
- Edit Guides comb strokes reversed and distorted when looking up at hair placed away from the world origin
- Arnold rendered the hair at the scene origin when the object was moved
- Arnold translator did not export the Min. Pixel Width parameter
- Clump Guides method and clump stem shapes followed the bottom-most stack guides instead of the ones that generated the hair
- Clumping became very slow with many strands when the amount ramp displaced the roots
- Mesh From Strands crash after lowering the hair count
- "Invalid strand index" warning when planting a guide after deleting one in Edit Guides
- Edit Guides with Surface tracking: untouched guides jumped and reverted when a stroke was composed
- Graft grooms sharing a file name were listed and loaded as the first one
- Graft groom fit scale is now measured on the surface area instead of the fit handle chord
- Graft surface vertex edits were ignored by the Wrap and Nearest fit methods with Soft Selection Iterations at 0
- Moov Physics ignored Friction and Restitution changes until the simulation was reset
