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

Core Web Vitals are now default metrics

Previously, we displayed Performance Score, First Contentful Paint and Time to Interactive as default metrics in Calibre. This meant that you’d see those three metrics across Your Sites, Pulse, Pages Leaderboard, Pull Request Reviews and Insights reports. Now, Core Web Vitals (Largest Contentful Paint, Cumulative Layout Shift and Total Blocking Time) are the default metric set.

Core Web Vitals are now the default metric set, which means you will see it across all Calibre reports.
Core Web Vitals are now the default metric set, which means you will see them prominently displayed across all Calibre reports.

Core Web Vitals have been actively improved for several years and provide a holistic view on different aspects of user experience. Google also uses them as ranking signals for page experience. You can see Core Web Vitals across the previously mentioned areas. You can still customise metrics displayed in Pull Request Reviews, Pages Leaderboard and Pulse if you’d like to amend them. All measurements are colour-coded, so you know if they’re good (green), need improvement (orange) or poor (red).

In the future, we’ll be introducing more ways of view and metric customisation, as well as keeping track of KPIs.

Sign up and log in with Google

We introduced Google Single Sign-On, so you can quickly sign up and access your Calibre account. With Google SSO, you are also benefitting from an additional security layer protecting your account.

You can change the way you sign in to Calibre in Profile Settings.

If you’re new to Calibre, choose from email or Google-based registration. If you’re already using the platform, you can migrate to using Google authentication at any time.

Easily delete your account

We know it’s essential always to control your data and be able to delete your account without needlessly contacting support. Now, you can delete your personal account in two clicks if you don’t want to use Calibre anymore.

Lighthouse 8 and Chrome 91

Our Test Agents now use the latest Lighthouse 8 and Chrome 91 to test your Sites. Lighthouse 8 comes with a few notable changes to metric collection and Performance Score calculation. Here’s a handy explainer of what you might notice in your metrics.

Open Source: React Live Chat Loader supports Chatwoot

React Live Chat Loader now supports Chatwoot and five other live chat providers. If you’d like to decrease the negative speed impact of live chat, install react-live-chat-loader through npm and implement it in your React application.

New documentation: Delete personal account and manage your profile

We documented the difference between deleting an organisation (cancelling your subscription) and deleting a personal account. We also refreshed how to manage your profile: name, surname, email address, avatar and method of authentication.
