v8.0.0

Full Changelog

We expect this release to ship in the DevTools of Chrome 93, and is already in PageSpeed Insights!

Notable changes

• The Performance Category had a number of scoring changes to align with other performance tools and to better reflect the state of the web.

  • The Performance Score has been reweighted (#12577)
  • The TBT and FCP score curves have been updated (#12576, #12556)
  • CLS has been updated to its new, windowed
    definition (#12554)

  See the v8.0 Performance FAQ for more detail.

  

• The report includes a new metric filter. Pick a metric to focus on the opportunities and diagnostics most relevant to improving just that metric:

  

• The Lighthouse Treemap is now available across all the major Lighthouse clients. If your site exposes source maps to Lighthouse, look for the "View Treemap" button to see a breakdown of your shipped JavaScript, filterable by size and coverage on load.

🆕 New audits

• The new audit csp-xss has been added to Best Practices to evaluate Content Security Policies and suggest ways of making them more secure. This can be a challenging audit to pass depending on hosting environment and page content, so for now it is unscored (#12514, #12551)

🤖💥 Breaking changes for programmatic users

• Legacy metrics estimated-input-latency and first-cpu-idle have been deprecated, unweighted, and hidden since Lighthouse 6. They have now been removed (#12553)
• Starting with Node 13, Node is built with full-icu by default, so the very large intl polyfill has been removed from Lighthouse's dependencies. See the readme FAQ if you're stuck with small-icu but need localization support (#12426)
• Long-time audit uses-webp-images has a new ID, modern-image-formats. WebP is now rather mainstream, and this frees the audit to start including details on other cutting-edge image formats in the future (#12535)
• The image-elements artifact has been restructured for clarity (#12568)

🧱 Core

• navigate: only observe longtasks in PerfObserver (#12545)
• script-treemap-data: do not create nodes with blank names (#12569)

• treemap: add placeholder, gist, and file upload features (#12511)
• treemap: support passing gzipped data in url (#12509, #12519)

Notable Changes

We are releasing the Lighthouse Treemap!

You may already be familiar with treemaps thanks to webtreemap (which we use!) or source-map-explorer. With Lighthouse Treemap, you'll be able to view all the JavaScript bundles on your page easily from a Lighthouse report, in addition to some insights that may help reduce the amount of JavaScript on a page. The only requirement is that source maps are accessible (either publicly, or securely from the same computer that is running the Lighthouse audit).

We even collect code coverage data from Chrome, and extrapolate the coverage of individual modules in a bundle:

Note: this only takes into account a cold-load: code only used after user interaction will be marked as unused. Stay tuned for a future release, which will enable you to configure user flows and capture even more accurate performance insights.

If we detect a large module included by multiple bundles, we'll alert you of that too.

You can access Lighthouse Treemap from the report:

Currently, only reports generated with the Lighthouse Node CLI will connect to the Lighthouse Treemap App. We are working on adding this functionality to Lighthouse in DevTools and PageSpeed Insights.

v7.0.0

7.0.0 (2020-12-17)

Full Changelog

Lighthouse 7.0 includes a number of programmatic breaking changes and new audits in the Accessibility and PWA categories. There were some improvements in the accuracy of metric calculations, but it is not expected that Performance scores will change significantly for almost all sites. There may be larger changes in Accessibility and PWA scores due to the new audits.

This release is expected to ship in the DevTools of Chrome 89. It went live on PageSpeed Insights on Feb 19, 2021.

Notable changes

• A full-page screenshot is taken and used to improve the experience of viewing DOM element details. Now a thumbnail will be shown and clicking reveals a lightbox showing where in the page the DOM node lived. This screenshot increases the size of the Lighthouse JSON by ~33%. (#11769, #11768, #11829, #11846, #11852)
• The PWA Category changed fairly significantly.
  • The Installable group is powered entirely by the capability checks that enable Chrome's installable criteria. These are the same signals seen in the Manifest pane in Chrome DevTools. As such, the "Registers a service worker…" audit moves to the PWA Optimized group, and the "Uses HTTPS" audit is now included as part of the key "installability requirements" audit.
  • The Fast and reliable group has evaporated into thin air. 🌬 Now that revamped "installability requirements" audit includes offline-capability checking, we've removed the dedicated audits for checking if the current page and start_url respond with 200 when offline. Separately, the "Page load is fast enough on mobile network" audit was removed—while it's no longer part of the PWA section, we encourage folks building a PWA to consult the Performance category to ensure their web app is speedy and delightful.
• A nightly Lighthouse build is now available as lighthouse@next on npm. Note that while automated tests pass before publishing, it's expected that this version will be more unstable than the regular releases (#11792, #11805, #11810)
• The accessibility-testing library axe-core has been updated to the latest 4.1.1 release. The accessibility audits are now faster, more robust, and include multiple new checks (#11661)
• Lighthouse runs a small benchmark at startup, and will now include a warning if the test machine appears underpowered and may be affecting the accuracy of the Lighthouse metrics (#11350)
• Joomla and October CMS detection has been added, so pages on those platforms will now get customized advice on some Lighthouse audits (#11788)

New contributors

Thanks to Kohta Ito (@koh110) and Sam Stoelinga (@samos123) for their first contributions!

🆕 New audits

• The new installable-manifest PWA audit, mentioned above, uses Chrome's own installability criteria so it will always stay in sync with installability requirements (#11745)
• third-party-facades looks for third-party embeds in the test page that can be lazy loaded with a static "facade". If the embed isn't necessary for immediate interaction by a user, consider using one of the facades to speed up page load (#11290)
• With the axe version upgrade comes new audits ensuring accessible naming: aria-treeitem-name, aria-command-name, aria-tooltip-name, aria-meter-name, and aria-progressbar-name (#11661)

♻️ Removed audits

• The update to latest axe-core also removes two audits that weren't checking much: layout-table and video-description (#11661)
• works-offline and offline-start-url audits were removed as their checks are now covered by the new installable-manifest implementation (#11806)
• The load-fast-enough-for-pwa audit has also been removed since Lighthouse's existing performance metrics more than cover the needs there (#11764)
• without-javascript has been removed (#11711)

💥 Breaking changes

• Device-emulation config settings and CLI flags have changed to be clearer and have less overlap. If you've used --emulated-form-factor or other emulation-related configuration, you'll need to make changes. The new settings should be considerably simpler to use with custom Lighthouse runners using real devices, Puppeteer, or system-level throttling. See the emulation docs for migration guidance. (#11779)
• When waiting for the page to be fully loaded, Lighthouse will now wait if there are active high-priority network requests. In rare cases, like where the app initialization is dependent on a single, slow-returning XHR, some performance metrics may worsen; however, the new measurements are now accurate. (#11738, #11851)
• Support for Node 10 has been dropped. The minimum required Node version is now 12 (#11656)

🤖💥 Breaking changes for programmatic users

These changes are unlikely to affect end users, but may be important if you are writing custom configs, plugins, or processing the Lighthouse JSON output.

• ConsoleMessages is a new artifact that is a combination of the old ConsoleMessages and RuntimeExceptions artifacts, with some expanded data on items logged to the console. RuntimeExceptions has been removed (#11663)
• DOM "node details" data formerly spread throughout existing artifacts are now gathered in a NodeDetails property on each element (#11474, #11695, #11752)
• The ImageElements artifact has been streamlined to better represent the data collected and how it's used (#11703, #11707, #11733)
• Previously, extends: true was allowed as an alias for extends: 'lighthouse:default' to extend a config from the default Lighthouse config file. The boolean option has been removed to prepare the way for extending from any valid config file (#11835)
• A never-used feature to pass options from the config to gatherers has been removed to be compatible with future changes (#11743)

🧱 Core
