So who's all attending @WeLoveSpeed in Paris this week?

Really looking forward to it and hoping my (very, very basic!) French will hold up to still enjoy some of the French talks as well as the English ones.

Come say hi if there and have any #webperf or CWV questions!

We've updated the Web Vitals extension to provide more useful debugging information to help you optimise your Core Web Vitals.

Ohhh... lookie here.

Fetch Priority works in the latest Safari Tech Preview (note it needs to be enabled in Develop->Experimental Features).

I am thrilled to share with you all that I have been awarded the Google Open Source Peer Bonus for my work on the @MYVaccineCount.

Special thanks to @tunetheweb nominating me for this honor.

We've updated our Optimizing CLS guide to give more guidance.

When CrUX field data matches Lighthouse lab data, that indicates you have a "load CLS" issue.

When they differ, you likely have a "post-load" issue

Read the guide to see how to handle both:

How do all you #webperf people debug CLS issues? Particularly post-load CLS issues that aren’t picked up by PSI/Lighthouse or DevTools Perf trace.

DevTools? Web Vitals extension? RUM attribution? Something else?

Updating docs and tooling and keen to hear what y'all currently do.

We've two names for the same feature: Priority Hints and Fetch Priority. That's a bit confusing!

So the
@developers team have decided to try to consolidate on "Fetch Priority" going forwards.

We've updated the docs (with a redirect and a note):
