  MCP Bridge for Claude.ai - Release Notes (v1.0.2)
================================================================================

WHAT'S NEW
================================================================================

  Auto-Connect on Page Load
  --------------------------
  - Enabled MCP servers now connect automatically when you open Claude.ai
  - No more manual toggling required after a page refresh
  - Tools appear in Claude.ai as soon as the connection is ready

  Reliable Tool Injection
  -----------------------
  - Fixed race condition where tools failed to appear in Claude.ai on the
    first page load despite the server connecting successfully
  - Extension now waits for Claude.ai's UI to fully mount before handing
    off the connection, preventing missed messages
  - Toggling a server off in Manager now immediately disconnects it from
    Claude.ai without requiring a page refresh

  Manager Page Cleanup
  --------------------
  - Manager page now properly disconnects all active connections when
    the tab is closed, preventing orphaned background connections


BUG FIXES
================================================================================

  - Fixed disabled servers occasionally still attempting to connect
  - Fixed server config sent to page context could include raw unsanitized
    server data on storage changes (now always sanitized via allowlist)
  - Fixed connection resource leaks: port1 channels, pending request Maps,
    and warning timeouts are now properly cleaned up on disconnect
  - Fixed concurrent syncConnections() calls causing race conditions when
    toggling servers rapidly (mutex guard added)
  - Fixed disconnect() being unsafe to call multiple times (idempotency guard)
  - Fixed stale "Claude.ai hasn't responded" warnings firing after a server
    was already disabled
