This is a major version upgrade from Lighthouse v6 to v7, which introduces significant breaking changes for programmatic users of the Node CLI and module.

Key Breaking Changes:

• Node API: The function signature for running Lighthouse has changed. The second argument is now an options object, and the config is now a property on that object (options.config). Previously, flags and config were separate arguments. Code using the Node module must be updated to this new structure.
• LHR (JSON Report) Structure: The structure of the Lighthouse Horizontal Rule (LHR) object has been modified. The audits object is no longer a flat map at the root of the LHR; consumers will need to adjust their parsing logic to account for the new format.
• Metric Updates: The definition of Cumulative Layout Shift (CLS) has been updated to include shifts from subframes. This may result in different CLS scores and requires re-baselining of performance metrics.
• Audit Changes: The redirects audit has been removed, and its data is now incorporated into the server-response-time audit.

Recommendation: Developers using the Lighthouse Node module or parsing its JSON output must review the v7.0.0 release notes and update their integrations to support the new API signature and LHR report structure. Thoroughly test and re-baseline performance metrics due to the change in CLS calculation.
