@brendankenny brendankenny released this Oct 2, 2019

5.5.0 (2019-10-02)

Notable changes

  • Preliminary implementation of the Largest Contentful Paint metric has landed (devtools and provided throttling only) and can be found in the hidden metrics audit in the raw LHR JSON (#9706)
  • The creation of main-thread tasks from a trace is now more robust. This should significantly reduce the occurrence of Issue #7764, "Fatal trace logic error - expected start event, got X" (#9491)
  • <script> element id has been added to the ScriptElements artifact (#9718)
