#### New Features

* Handles - Added visual viewport handles for editing Scale, Twist, Spiral Radius, and Spiral Turn Distribution. (Toggle handles with the E button, exit with W,E,R key)
* Added a new live Spiral Mode with Radius, Turns, Phase, and ramp controls.
* Added a redesigned Profile Curve CV Editor with direct selection, movement, scaling, CV point insertion, deletion, and Multi Edit functions.
* Added viewport edge-loop highlighting for selected Profile CVs, including Smooth Mesh Preview support.
* Added Linear and Cubic Profile interpolation.
* Added Profile copying and pasting to individual, selected, or all Profiles. Right clicking on the profile curve button to show the options.
* Added Crease and UV reference previews directly in the Profile editor.
* Added Spiral controls to the Randomizer.
* Added customizable handle and Profile-highlight display settings to Scene Presets.

#### Workflow Improvements

* Reorganized the Strand Editor into clearer Shape, Spiral, UV/Crease, Aim, and Misc tabs.
* Improved Profile placement with a position strip and viewport Profile Handles.
* All Profiles are now always visible; checkboxes define Multi Edit and batch-paste targets.
* Improved Profile list layout, active-Profile styling, and insertion/removal controls.
* Added Clear for Crease assignments and allowed removal of the final creased CV.
* Strand Presets, Copy/Paste, Mirror, Duplicate, and Update to Current now support Spiral and Profile interpolation.
* Applying a new Shape or Strand Preset now clears obsolete CV selections.
* Older strands can be upgraded through Update to Current directly in the Strand Editor, without the need to go to Menu.
* Twist Reset (R button) will now reset the Twist value.
* Improved Ramp stability by disabling Maya’s unsafe Ctrl-hover deletion behavior.
* Added a warning when Distribute Evenly is used without any middle Profiles.

#### Fixes

* Fixed Ramp graphs being cropped and restored their bottom deletion controls.
* Fixed Scale and Twist Ramp horizontal flipping.
* Fixed Profile scaling passing through zero and mirroring CVs.
* Fixed Profile Handles crossing neighboring Profiles.
* Fixed Crease and UV assignments shifting to the wrong CV after Profile topology edits.
* Fixed errors after deleting the strand currently displayed in the Strand Editor.
* Fixed the Strand Editor reopening at an excessively wide size.

#### Known Issues

* Deleting all CVs in Profile CV Edit is currently possible and may cause errors. To recover, use Shape > Pick a Preset Shape.
* Crease/UV highlighting may lag behind changes to the tube shape.
* On Linux/VM machines, Handles may not register the mouse button release callback correctly, causing them to appear sticky. As a workaround, try Alt + LMB or MMB to move the viewport. (Planned to be addressed in V15.07.02.)
* Ctrl + LMB will remove selected CVs even when clicking outside the profile curve.
* <mark style="color:$danger;">After saving a scene, and restarting Maya, upon opening the saved scene, hair tubes would appear missing with only curves in place.</mark>&#x20;
  * We are pushing a hotfix for this, in the mean time, please follow these steps:
  * Open Strand Editor > Select a curve > click Update to Current button. Your scene will still appear broken at this stage.&#x20;
  * Reopen the same scene. And your scene should now be back to normal.
