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

See more metrics and benchmarks after creating a Site

We redesigned the email you receive after adding a new tracked Site to Calibre. Now, you can see three key metrics—Performance Score, Time to Interactive and Largest Contentful Paint and how they compare to the Calibre test dataset. This change should bring more context into where your Sites are at from the very first minutes of testing.

Initial Test email showcasing key metrics and benchmarks for the Site.

Additionally, all of our other emails also got a splash of new paint to match.

Extend testing capability with Test Packs

We launched Test Packs to allow increasing testing capacity without upgrading your Plan. Each Test Pack adds 5,000 tests to your account and can be added or removed at any time, depending on your needs.

Add or remove Test Packs to control testing capacity without changing your Plan.

Learn how to use Test Packs or add one in Billing → Overview by clicking the Change plan and manage Test Packs button.

Inspect Pull Request Reviews test usage

You can now see how many tests were generated with Pull Request Reviews. If you are an administrator, head to Billing → Overview and click the Show per Site usage link.

The test usage will be split between Snapshots and Pull Request Reviews.

New documentation: GraphQL API and Test Packs

We documented the Calibre GraphQL API that powers the CLI and Node.js API. While it might work for your use case, we recommend trying to use other automation options before resorting to GraphQL as the API might change without prior notice.

We explained how managing Test Packs works, so you can make most of your extra test allotment.

CLI 3.1.0

A minor version of the CLI has been released with the addition of milliunit measurement support. This will be necessary to report the Cumulative Layout Shift metric once Lighthouse 6 is available.

React Live Chat Loader now supports Facebook Messenger

React Live Chat Loader, our open source component that mitigates the negative performance impact of live chat tools, now supports Facebook Messenger.

If you are using Intercom, Help Scout or Facebook Messenger in your React-powered site or application, you will be able to use the component out of the box and improve your performance metrics. To see its benefits, read about how we improved the speed of our live chat by 30%.

Upcoming releases: Lighthouse 6

We are preparing for the upcoming Lighthouse 6 release, scheduled sometime in May. Calibre is already capable of running the latest Lighthouse beta and the infrastructure will be upgraded once a stable version is available.

Key differences between Lighthouse 5 and 6 scoring algorithm for Performance Score.

Lighthouse 6 introduces many additions and improvements—one of the biggest ones being the change to Performance Score algorithm that most likely will affect your scoring. We wrote about the most important developments, so you can be ready when not only Calibre but also Page Speed Insights and Chrome Developer Tools switch to using the newest version.
