 ## Features
 
-### Real-time Updates
-The change log updates live across all open browser sessions without any page refresh — powered by **Server-Sent Events (SSE)**:
-- **Instant propagation** — when any user registers, edits, or deletes a change, every connected client sees the update immediately
-- **Connection status indicator** — a green pulsing dot in the nav bar shows the live connection; turns amber with "Reconnecting" if the stream drops
-- **Exponential backoff reconnection** — the client automatically reconnects with 1s → 2s → 4s … capped at 30s backoff
-- **Smart fallback** — when the SSE stream is offline, the UI falls back to a manual refetch after mutations so data stays consistent
-- **JWT-authenticated stream** — the `/api/events` endpoint validates the session token; API keys are intentionally not accepted on the SSE endpoint to avoid long-lived credentials appearing in server logs

 ### Change Management
 - **Register Changes** - Log infrastructure, deployment, and configuration changes with rich metadata including system, environment, change type, and detailed descriptions
 - **Real-time Filtering** - Filter changes by system, environment, user, change type, and time range
