| Category | Enhancement | Practical Impact | |----------|-------------|-------------------| | | Improved handling of gradients, embedded fonts, and transform attributes. | Designs created in Inkscape or Illustrator retain visual fidelity, reducing manual clean‑up. | | Dynamic Power Preview | Real‑time color‑coded overlay showing power variations along a path (green = low, red = high). | Instantly see if a “power‑ramp” will produce the intended effect; reduces trial‑and‑error. | | Heat‑Map Simulation | Overlays cumulative energy per square‑mm on the workpiece preview. | Helps avoid scorching or under‑exposure on dense engraving areas. | | Batch Export Wizard | Guided interface to export many files to LBRN , DXF , SVG , or G‑code in one go. | Saves hours when preparing a catalog of parts for production. | | Pause/Resume Improvements | Multi‑pass jobs now resume exactly where they left off, preserving the pass counter. | No need to restart long jobs after a brief interruption. | | Air‑Assist Integration | Added a dedicated UI control that can toggle the air‑assist on/off during a job (via controller command). | Enables fine‑tuning of cutting quality for thin materials. | | Enhanced MacOS Compatibility | Resolved a lingering issue with permission prompts on macOS 14 (Sonoma). | Installation is smoother and the app runs without “requires admin” warnings. | | Bug Fixes & Stability | • Fixed a rare crash when loading large (>200 MB) raster images. • Resolved occasional UI freeze when editing text objects with long strings. • Minor performance boost for the UI on low‑end GPUs. | Overall smoother user experience, especially for high‑resolution jobs. |
