Performance Newsletter
[issue 88]()
 
#### Editor’s note
 

Not that long ago, many of us started monitoring and improving Core Web Vitals—the [new generation of web performance metrics](https://calibreapp.com/blog/new-generation-of-performance-metrics). Since then, the page speed space has been moving rapidly.

Now, we’re looking at least two new metrics to measure responsiveness and animation. While those developments are likely to be positive, it’s hard to navigate a constantly changing landscape. This task becomes even more challenging when we need to communicate changes across teams, roles and varying degrees of web performance knowledge. We need to become experts to relay those developments.

But, in becoming an expert, we must not rely on complexity and jargon. Transparency and direct communication go a long way.
