Release notes

✨ What's New in v1.2.0

This release introduces a plugin system, custom AI providers, and a set of reader quality-of-life features. It also removes the mobile companion to keep the desktop experience focused.


🚀 Major Features

  • 🧩 Plugin System — first-class extension API
    • Sandboxed plugin runtime loaded from user-data folder
    • Manifest loader with version, permissions, and min-Helix-version checks
    • helix-plugin:// custom protocol serving plugin UIs into sandboxed iframes
    • Permissions model + per-plugin storage API
    • Plugin Manager UI: install from folder, enable/disable, uninstall, reload
    • Full authoring docs (docs/PLUGIN_AUTHORING.md) and a hello-world example
  • 🤖 Custom AI Providers — bring your own OpenAI-compatible endpoint
    • Add / edit / remove / test custom providers
    • Stored in a dedicated custom store and exposed alongside built-in providers in the Providers page

📖 Reader Experience

  • 🔖 Bookmarks Panel — in-article bookmarks with labels, section anchors, and scroll-position recall
  • ⏱️ Reading Time Badge — estimated minutes-remaining on every article
  • ▶️ Resume Pill — one-tap jump back to the last position in the article you were reading
  • 🕘 Recents Section — sidebar-friendly recents with quick remove and clear-all
  • 🧠 Graph view — large rewrite of the knowledge-graph page for faster layout and cleaner visuals
  • 📄 Providers page — redesigned for custom providers and clearer key management

🌍 Translations

  • 🌐 Five-locale coverage kept in sync across the new screens: en, ar, fr, es, de

🗑️ Removed

  • 📱 Mobile companion — the embedded HTTP server, PIN auth, mobile web UI, and "Mobile companion" settings tab are gone
    • Drops the qrcode and @types/qrcode dependencies
    • Existing users: leftover {userData}/Helix/mobile-settings.json is harmless and can be deleted manually

⚙️ Build & Release

  • 🛠️ CI: streamlined release pipeline — direct uploads to the Helix-releases repo, fixed release-creation ordering, fixed Windows shell path handling
  • 📦 Bumped product version to 1.2.0

📝 Notes

  • A package-lock.jsonbun.lock drift exists from prior development; CI uses npm install and will refresh the lockfile on the next developer build
  • The on-disk schema is unchanged — existing libraries, notes, bookmarks, and flashcards migrate cleanly
