New Website, Extensive Documentation, Largest Contentful Paint and More

Release Notes is a monthly summary of new features and product improvements.

New website and documentation

We’ve spent the last few months reimagining the Calibre brand, but even more importantly, designing a better experience for learning about our product and web performance at large. Now you can easily discover features and determine which ones will be most relevant to what you’re trying to achieve.

Because performance education is crucial, we’ve revamped our documentation to include not only information about Calibre but also important web performance concepts. We’ll be publishing even more over the upcoming months.

Find out how to get started with Calibre as a platform, start using our CLI, tag deployments on charts or learn about performance metrics.

New Metric: Largest Contentful Paint

Largest Contentful Paint (LCP) is a new, user-centric metric describing perceived speed by reporting the render time of the largest content element on the page. It differs from First Contentful Paint and First Meaningful Paint by pinpointing when the page’s content is most likely already rendered. Learn more about LCP in our docs.

You can add Largest Contentful Paint to the Pulse page through customising the Metric History view and set budgets against it.

Navigate between Snapshots more easily

On Snapshot page, we’ve added a link to the page that has been tested so you can now easily access it. Also, when viewing Pulse, you can click on a Test Profile name to inspect results for that specific profile in a given Snapshot. Less clicking around!

Reorder Pages

You can now reorder your Site’s Pages under Settings → Pages. On both Pulse and Snapshot view, items in the Page dropdown will be arranged accordingly to your choosing rather than the order they were added in.

Either by using reordering or filtering, you’re able to access relevant pages quicker, especially when testing sizeable sites.

Lighthouse 5.6

Our agents now use the latest Lighthouse release, 5.6.0, which means parity with Chrome Developer Tools and Lighthouse Chrome Extension.
