Check the Chrome changelog for the most recent changes. Updates that may influence mPulse metrics include:

Chrome 133+: Cross-origin Largest Contentful Paint elements (such as images) without the Timing-Allow-Origin HTTP now return LCP time with greater accuracy (up to 4 milliseconds of granularity). This change may increase the LCP time for websites with cross-origin content.

See the Chrome Platform Status documentation and When Is LCP Reported? at Web.dev for more details.
Chrome 115-133: Changed responseStart's definition to the start of the final document response which affected NavigationTiming and Early Hints. Chrome 133 reverted this update after compatibility issues.
