New Features

Profiler: Introduce new onCommit and onPostCommit hooks to enhance performance tracking during component rendering, providing developers with more detailed insights.
Event System: Add support for the useEvent hook, enabling components to attach event listeners directly to DOM elements, improving event handling in React applications.
DevTools: Improve the editing interface by allowing users to rename object keys and add or remove properties from objects and arrays, enhancing the overall user experience.
Profiler: Introduce a new prop to the Suspense component type, unstable_expectedLoadTime, which allows React to skip over expensive trees during the initial mount, improving performance for complex applications.
React: Introduce a new useMutableSource hook that allows components to subscribe to mutable sources, enhancing state management capabilities.

Improvements

DevTools: Enhance the context test harness for better testing capabilities, making it easier to validate component behavior in different contexts.
DevTools: Improve the error boundary handling by adding support for dark mode and a retry option for corrupted profiler data, enhancing usability.
React: Improve the performance of input updates by decreasing the expiration time from 1000ms to 250ms, allowing for more responsive user interactions.
DevTools: Enhance the Components panel with resizing support, allowing users to adjust the panel size for better visibility and usability.

Fixes

Fix: Resolve an issue where the Profiler would crash when inspecting certain components, ensuring a smoother debugging experience.
Fix: Address a bug that caused the DevTools to display incorrect error messages when inspecting document elements, improving the reliability of the tool.
Fix: Prevent phishing attacks by ensuring that links opened in new tabs do not have access to the original page's window object, enhancing user security.
Fix: Resolve an issue where the useMutableSource hook would not properly handle updates, ensuring that components remain in sync with their data sources.

Others

DevTools: Update the interface to allow users to switch between rendered components using keyboard arrow keys, improving navigation efficiency.
DevTools: Add a feature to break on warnings, allowing developers to pause execution when a warning is triggered, facilitating easier debugging.
