What's new in v0.4.1

  • Shadow DOM support — browser_get_state pierces open shadow roots; shadow inputs and buttons are now reachable as stable refs.
  • Deterministic dialog handling — native JS dialogs are auto-handled (default: accept). browser_handle_dialog sets the policy for subsequent dialogs.
  • Stale-ref auto-retry — element resolution retries once on transient layout failures.
  • Extended observability profile — 15 new tools available via --extended (AGENTYC_EXTENDED=1): console logs, network log, mocks, conditions, request replay, debug bundle, downloads, trace.
  • Token-bounded outputs — browser_get_html and browser_extract_content are now bounded to avoid blowing agent context windows.
  • min is the default get_state mode — smallest reliable payload for agents by default.
  • Deadlock fix — all cdp() helpers now release the state lock before awaiting, preventing any click→dialog hangs.
