Newton Browser 0.4.0

[0.4.0] - 2026-07-11

Added

• MIT licensing and package metadata.
• Extension visual identity, generated PNG master icon, toolbar connection state, and deterministic icon packaging.
• CI and release workflows; newton-browser npm packaging via npx, a Node 20 runtime floor, and a --install <client> config helper.
• First-run onboarding page and a minimal session-visibility popup with a stop-all control.
• Host/extension version-skew reporting on browser.status.
• browser.observe text mode (mode:"text") returning bounded, redacted page text.
• JavaScript dialog handling: dialog_accept (with promptText) and dialog_dismiss act kinds, plus pendingDialog on observations.
• Owned-tab viewport resize act kind, persisted across debugger re-attach.
• Batch fill_form act kind with per-field floor and stop-on-first-failure.
• Read-only browser.console and browser.network tools (headers never exposed; network bodies origin-gated).
• Screenshot region capture and format:"jpeg"/quality encoding.
• Privacy-preserving owned sessions with browser.session.start({ incognito: true }),
  including typed incognito_not_allowed guidance when extension access is disabled.

Fixed

• Host-side observation redaction is now wired into the live result path, so accessible values and mode:"text" page text reach the client secret-redacted (BB-035).

Security

• Renamed from Browser Bridge to Newton Browser; retired the old env-var prefix, auth protocol id, and config directory.
