+## Updating sample artifacts and LHR JSON
+
+```
+yarn run update:sample-artifacts # update all artifacts
+yarn run update:sample-artifacts ScriptElements # update just one artifact
+yarn run update:sample-json # update sample LHR based on sample artifacts

+When updating artifacts, usually you'll need to revert changes to the `*.devtoolslog.json` and `*.trace.json` files and manually review changes to `artifacts.json` to make sure they are related to your work.

 ## Tracking Errors
 
 We track our errors in the wild with Sentry. In general, do not worry about wrapping your audits or gatherers in try/catch blocks and reporting every error that could possibly occur; `lighthouse-core/runner.js` and `lighthouse-core/gather/gather-runner.js` already catch and report any errors that occur while running a gatherer or audit, including errors fatal to the entire run. However, there are some situations when you might want to explicitly handle an error and report it to Sentry or wrap it to avoid reporting. Generally, you can interact with Sentry simply by requiring the `lighthouse-core/lib/sentry.js` file and call its methods. The module exports a delegate that will correctly handle the error reporting based on the user's opt-in preference and will simply no-op if they haven't so you don't need to check.

+[Full Changelog](https://github.com/googlechrome/lighthouse/compare/v4.3.0...v5.0.0)
+
+## Major new features
+
+* [Stack packs](https://github.com/GoogleChrome/lighthouse-stack-packs) are a new way to present stack-specific advice wihin the Lighthouse report. This initial version detects if a site is running on WordPress and adds additional information to the report on how to take advantage of Wordpress plugins and configuration to improve performance. ([#7243](https://github.com/googlechrome/lighthouse/pull/7243), [#8169](https://github.com/googlechrome/lighthouse/pull/8169), [#8633](https://github.com/googlechrome/lighthouse/pull/8633), [#8536](https://github.com/googlechrome/lighthouse/pull/8536), [#8778](https://github.com/googlechrome/lighthouse/pull/8778))
+* [Performance budgets](https://developers.google.com/web/tools/lighthouse/audits/budgets) are a new feature of Lighthouse to help prevent your site performance from regressing over time. Set budgets for the resources a page should load and have Lighthouse alert if the budgets aren't met. ([#8539](https://github.com/googlechrome/lighthouse/pull/8539), [#8522](https://github.com/googlechrome/lighthouse/pull/8522), [#8727](https://github.com/googlechrome/lighthouse/pull/8727), [#8709](https://github.com/googlechrome/lighthouse/pull/8709), [#8427](https://github.com/googlechrome/lighthouse/pull/8427), [#8708](https://github.com/googlechrome/lighthouse/pull/8708))
+* The HTML report has been redesigned!
+
+## New Audits
+
+* `apple-touch-icon` PWA audit ([#8857](https://github.com/googlechrome/lighthouse/pull/8857))
+* `max-potential-fid` (new in HTML report) ([#8729](https://github.com/googlechrome/lighthouse/pull/8729), [#8817](https://github.com/googlechrome/lighthouse/pull/8817))
+* `performance-budget` ([#8539](https://github.com/googlechrome/lighthouse/pull/8539))
+* `resource-summary` ([#8522](https://github.com/googlechrome/lighthouse/pull/8522))
+
+## Breaking changes
+* Node 10 (LTS) or later is now required. ([#8117](https://github.com/googlechrome/lighthouse/pull/8117))
+* `rawValue` has been removed from audit results. If the audit had a meaningful numeric result (like a metric), this result will now be on `numericValue`. ([#8343](https://github.com/googlechrome/lighthouse/pull/8343), [#8385](https://github.com/googlechrome/lighthouse/pull/8385), [#8421](https://github.com/googlechrome/lighthouse/pull/8421))
+* The accessibility category scoring has been reweighted based on severity. ([#8823](https://github.com/googlechrome/lighthouse/pull/8823))
+* FCP accuracy has improved (in 'simulation' throttling) and may noticeably affect scores. ([#7513](https://github.com/googlechrome/lighthouse/pull/7513))
+* The deprecated `--disable-device-emulation` flag has been removed. Use `--emulated-form-factor`. ([#8289](https://github.com/googlechrome/lighthouse/pull/8289), [#8334](https://github.com/googlechrome/lighthouse/pull/8334))
+* The `dom-size` now ignores elements in `<head>` and limits scoring to only DOM nodes in the body. ([#7241](https://github.com/googlechrome/lighthouse/pull/7241))
+* The `diagnostics` audit details have had their `type` value changed to `debugdata` ([#8298](https://github.com/googlechrome/lighthouse/pull/8298))
+* The format of the `screenshot-thumbnails` screenshots has changed. They are now a full image data URL. ([#8299](https://github.com/googlechrome/lighthouse/pull/8299))
