12.2.3 (2024-12-02)

Full Changelog

This release is only for PageSpeed Insights and we expect it to ship within 2 weeks.

Notable Changes

The CPU throttling factor for PageSpeed Insights has been adjusted (#16256) to account for the low CPU performance benchmarks typical in PageSpeed production environments. In general, TBT metric times for all sites should improve when testing with PageSpeed Insights.

All other Lighthouse clients (Lighthouse CLI, the Node API, Lighthouse panel in DevTools, etc) should not be affected by this change.

Tests

• inline-fs: fix error in Node 20 (#16262)
