React Panel V3's recent release introduced significant performance improvements, reducing load times from 30 seconds to 13 seconds with their suspense data cache layer, and now with V3, they optimized data collection for the entire DOM tree to enable instant element expansion and enhanced keyboard navigation. The update includes a detailed exploration of how Andarist leverages Replay DevTools to debug the TypeScript Compiler, offering insights into the internal workings of TypeScript's type inference. Additional updates feature enhanced WebSocket event handling in the Console Event Listeners and a migration focus on Chromium, leading to Firefox recordings being redirected to legacy.replay.io. Moreover, users can now search for elements by XPath or node text, a long-desired feature made possible by having access to the complete tree.
