+
+## Notable Changes
+
+### PWA Category Removal
+
+As per [Chrome’s updated Installability Criteria](https://developer.chrome.com/blog/update-install-criteria), Lighthouse [has removed the PWA category](https://github.com/GoogleChrome/lighthouse/pull/15455). For future PWA testing, users will be directed to use the [updated PWA documentation](https://developer.chrome.com/docs/devtools/progressive-web-apps/).
+
+### SEO Category Reorganization
+
+The SEO category has been updated to reflect the priorities of Google search in 2024. As such, several audits have been removed or moved to other categories:
+
+* The `is-crawlable` audit is now weighted high enough to fail the SEO category on its own. ([#15933](https://github.com/GoogleChrome/lighthouse/pull/15933))
+* The `viewport` and `font-size` audits are no longer priorities for SEO, but are still important for UX in general so they have been moved to the best practices category. ([#15930](https://github.com/GoogleChrome/lighthouse/pull/15930))
+* The `plugins` audit is no longer a priority for SEO and has been removed. ([#15928](https://github.com/GoogleChrome/lighthouse/pull/15928))
+* The `tap-targets` audit is no longer a priority for SEO and has been replaced with the `target-size` audit in accessibility. ([#15906](https://github.com/GoogleChrome/lighthouse/pull/15906))
+
+### Overall Savings Deprecation
+
+The `overallSavingsMs` value on performance diagnostic audits has been deprecated ([#15902](https://github.com/GoogleChrome/lighthouse/pull/15902)). We recommend using `metricSavings.LCP` or `metricSavings.FCP` to understand the estimated metric savings of performance diagnostics.
+
+### 🆕 New Audits
+
+* The [`aria-conditional-attr`](https://dequeuniversity.com/rules/axe/4.9/aria-conditional-attr), [`aria-deprecated-role`](https://dequeuniversity.com/rules/axe/4.9/aria-deprecated-role) and [`aria-prohibited-attr`](https://dequeuniversity.com/rules/axe/4.9/aria-prohibited-attr) Axe checks have been added to the Lighthouse accessibility category. ([#15963](https://github.com/GoogleChrome/lighthouse/pull/15963))
+* The `redirects-http` audit has been brought back, but will only passively check for a http -> https redirect if the provided URL happens to be on http ([#13548](https://github.com/GoogleChrome/lighthouse/pull/13548))
+
+### Other Audit Changes
+
+* The `layout-shifts-elements` audit is removed. Improved layout shift information can be found in the `layout-shifts` audit. ([#15931](https://github.com/GoogleChrome/lighthouse/pull/15931))
+* The `no-unload-listeners` audit is removed. Unload listeners are deprecated and are still flagged in the `deprecations` and `bf-cache` audits. ([#15874](https://github.com/GoogleChrome/lighthouse/pull/15874))
+* The `duplicate-id-active` audit is removed because it's corresponding Axe check is deprecated. ([#15900](https://github.com/GoogleChrome/lighthouse/pull/15900))
+* The `uses-rel-preload` and `preload-fonts` audits have been moved to the experimental config. Preload advice is still on hold and these audits were already in a disabled state. ([#15876](https://github.com/GoogleChrome/lighthouse/pull/15876))
