New:
- Cycles renderer with a new Realistic display mode alongside Raytraced (ProRender), including GPU rendering via CUDA with zero-copy Vulkan interop
- Default Cycles hair material with per-strand hue variation and root-to-tip lightening
- GPU denoiser for the ProRender and Cycles viewports
- Implicit viewport lights (two point lights plus ambient) shared across all display modes
- Flat display mode and a configurable viewport background gradient
- Orthographic views with camera/view switching, view-name UI and shortcuts
- Per-plane orthographic grids with coplanar fade; viewport grid on by default and stored with the groom
- Orientation tripod: click the axis tips to switch views
- Operator Stack quick-add bar of context-aware operators
- Operator Stack display modes (Focused / Final / Both)
- Edit Texture tool to visualize texture operator output, procedural texture node creation, and texture-map preview thumbnails
- Operator properties ordered to match Maya, parameter sets as toggleable tabs, and shared headers/presets across property views
- Freeze (non-selectable) toggle and show/hide icons for scene geometry
- Copy / Cut / Paste of scene nodes and operators
- Click-and-drag on viewport shortcut hints
- Groom Properties view to view and edit groom parameter scripts
- Recursive groom folder browsing, New from Template menu, automatic groom thumbnails, Recent Files thumbnails with hover preview, and a dedicated Thumbnail view
- .oxz file association and command-line loading; drag-and-drop of grooms and importable files into the window
- Embedding of referenced files into groom archives, and automatic per-scene directory management and file-path resolution
- Target-host primvar export for Alembic and USD
- OBJ and FBX mesh importers
- Improved graft-groom surface fitting (Wrap and Geodesic projection, anchor-based editing)
- Interactive Python console, an MCP server for driving the app, and a built-in profiler with session capture
- macOS and Linux support
- Automatic update check with guided installer download
- Main window position, size and maximized state persisted across sessions

Fixed:
- Selection and other colors not visible in wireframe display mode
- Graft surface presets losing their mesh on save; thumbnails and icons rendering too bright
- Modal dialogs dimming the background the wrong way
- Intermittent crashes/hangs on startup, on scene fetch, when reparenting scene nodes, when creating a graft groom, and when deleting a node in the Node Graph
- Focused clump/overlay hair not showing in the Raytraced and Realistic viewports
- Brushes and selection affecting strands hidden behind the character mesh
- Orthographic hair-width, near-plane clipping and transform-gizmo scaling issues
- Paint Texture tool selection, color, and behavior on grooms with both mesh and hair
- Viewport overlay and stale-frame glitches when switching display modes
