+## What's New in v1.2.0
+
+**Friction reduction release** — fewer steps, faster output, smarter defaults.
+
+- **Auto-clipboard** — All 8 content commands (`post`, `quick`, `react`, `pipeline`, `first-post`, `video`, `multiplatform`, `carousel`) automatically copy finished content to your clipboard. No more manual copy-paste
+- **Reduced interactive steps** — Angle, format, and post type are inferred from context. Maximum 2 questions per post (down from 4-6)
+- **Deterministic state management** — Post tracking, streak updates, and content history are handled by `state-updater.mjs` (pure functions, tested, no AI involved). Content history auto-prunes entries older than 90 days
+- **MCP image carousel pipeline** — `/linkedin:carousel` can generate professional slide images via mcp-image with text overlays (1080x1350, 3:4 ratio). Falls back to Mermaid diagrams or text-based slides
+- **Progressive onboarding** — New users see a cleaner experience: personalization score hidden until 3+ posts, voice guardian suppressed until 5+ voice samples
+- **iCal calendar integration** — `/linkedin:batch` generates an `.ics` file importable into macOS Calendar, Google Calendar, or Outlook. Each post gets a calendar event with reminders
