Released: October 19, 2026
🍏 Apple Silicon & Platform Architecture

  • Automated Installer Resolution: Added an intelligent preinstall routine to the macOS PKG installer that silently resolves Rosetta 2 in the background on Apple Silicon systems if missing.

🎵 Resilient Audio Engine & Importer
  • Direct YouTube Stream Fallback: When importing Spotify playlists, if metadata lookup times out or stream matches cannot be found, CrateIQ now automatically retries with direct high-speed YouTube audio search (ytsearch1:), dramatically increasing download success rates.
  • Python 3.12 Engine Modernization: Completely eliminated yt-dlp/SpotDL Python 3.10 deprecation crashes by upgrading local virtual environments to Python 3.12.15.
  • Anti-Bot Deno Runtime Path Linking: Dynamically links Deno into the execution PATH to seamlessly solve YouTube anti-bot JavaScript extraction challenges.
  • Precise Error Diagnostics: Failures now log exact reason strings instead of generic notices, simplifying troubleshooting.
🛡️ UI & DRM Clarification
  • Streamlined DRM Notification: Replaced cluttered top-of-page popups, modal dialogs, and floating toasts with a single, clean, dismissible banner directly beneath 📥 Playlist Importer PRO advising: "Enter the Artist - Song Title instead."
  • Port Conflict Auto-Freeing: Improved background server process teardown on port 5050 to prevent Address already in use errors on restart.
