🆕 New audits
largest-contentful-paint-elementis a companion audit that gives information about which element triggered the LCP (#10517, #10713).layout-shift-elementsis another companion diagnostic that gives information about the elements that shifted as the page loaded (#10702).unused-javascriptis an audit that has been kicking around for some time but is only now turned on by default. It accounts for what JavaScript was loaded but never executed during page load and estimates the load time that could be saved via code splitting, dead code elimination, or judicious use of the delete key (#9854).maskable-iconjust looks better on your homescreen, so this new audit encourages you to have at least one available in your manifest (#10370).timing-budgetexpands budget assertions to now be settable on all the performance metrics (#9901, #9925).charsetaudit ensures a proper character encoding for page content (#10284, #10389, #10689).image-size-responsivechecks that images have an aspect ratio and resolution that match well with how they are displayed on a page (#10460).axe-corehas unlocked a number of new accessibility audits:aria-hidden-body,aria-hidden-focus,aria-input-field-name,aria-toggle-field-name,duplicate-id-active,duplicate-id-aria,form-field-multiple-labels,heading-order(#9798).⚗️ Experimental audits
These audits are not yet part of the default Lighthouse experience, but they will provide performance advice based on analysis of a page's JavaScript bundles. They can be tested today on the command line with the
--preset=experimentalflag.legacy-javascriptrummages through your bundles looking for polyfills and bundler transforms that aren't necessary or are outdated (#10303, #10568, #10564).duplicated-javascriptalso takes a dive through a page's JavaScript looking for code that has ended up duplicated within bundles or across multiple bundles (#10314).unused-javascriptnow runs by default (as mentioned above), but when run underexperimental, the audit can use source maps to show what original source code was never run and could be postponed or eliminated (#10090).New contributors!

💥 Breaking changes
frameNavigatedevents are now used to track redirects, which means JS redirects are now accounted for when determining the run'sfinalUrl(#10339).mixed-contentpreset has been removed as it was not widely used and takes too long to be added to the default Lighthouse experience (#10159, #10750).fullpreset has been renamedexperimentalto signify that the code there may not be ready for running by default (#9930, #10311, #10333, #10585).installable-manifest: icons in the Web app manifest must be fetchable to be considered installable (#10168, #10320)🤖💥 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.
LH.Audit.Contextpassed into audits is now treated as immutable. If code previously pushed tocontext.LighthouseRunWarningsto get a top-level warning, it should now pass that back inrunWarningson the audit's product (#10555).Audit.computeLogNormalScorehas been redefined to specify log-normal curves with median and p10 points (dropping the "point of diminishing returns"). Existing audits have been moved to this new definition so that no score changes should occur (#10715).loadFailureModesetting has been added toConfigpasses to control behavior in case of page load failure. Previously this was implicitly controlled (e.g. no offline page available did not cause an error) (#9987)time-to-first-bytehas been renamedserver-response-timeto better reflect what is being measured by the audit (#10735).resource-summary:details.items.sizehas been renamed totransferSizefor clarity (#10700, #10743).🧱 Core
