What's new in 4.1.1

  • Angular tab: component tree; in development builds properties and signals (editable live), inputs, outputs, directives, listeners and providers.
  • State tab for Redux, Redux Toolkit, Zustand, NgRx, Jotai and every library that supports Redux DevTools: action log, state, diff, time travel.
  • Preact apps in the React tab.
  • Framework tabs appear only on pages that use that framework.
  • Resize handle rebuilt for phones: bigger touch area and a smooth drag even on older devices; double-tap to maximize.
