Changelog 23: Heat Maps 🔥
Blog post from Replay
Heat Maps have been introduced in DevTools to enhance debugging by allowing users to view function call counts in the outline view, making it easier to identify and refactor hot code or remove dead code. The Hit Count Tooltip now appears instantly instead of in 200ms, and all backend functionalities, including Heat Maps, are well-documented for user experimentation. Additional updates include a Multi Line Terminal feature for adding lines in the Console, bug fixes for flickering comments, and a new Focus Mode that sets the pause position as the start or end of a focus window. The Redux setup is being refactored to Redux Toolkit by its maintainer, Mark, with an invitation to join the Discord server for collaboration. A case study highlights how Replay facilitated debugging issues related to user prompts and comment loading in the Transcript, showcasing the tool's dynamic analysis capabilities.
