- 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, #8169, #8633, #8536, #8778)
- Performance 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, #8522, #8727, #8709, #8427, #8708)
- The HTML report has been redesigned!
apple-touch-iconPWA audit (#8857)max-potential-fid(new in HTML report) (#8729, #8817)performance-budget(#8539)resource-summary(#8522)
- Node 10 (LTS) or later is now required. (#8117)
rawValuehas been removed from audit results. If the audit had a meaningful numeric result (like a metric), this result will now be onnumericValue. (#8343, #8385, #8421)- The accessibility category scoring has been reweighted based on severity. (#8823)
- FCP accuracy has improved (in 'simulation' throttling) and may noticeably affect scores. (#7513)
- The deprecated
--disable-device-emulationflag has been removed. Use--emulated-form-factor. (#8289, #8334) - The
dom-sizenow ignores elements in<head>and limits scoring to only DOM nodes in the body. (#7241) - The
diagnosticsaudit details have had theirtypevalue changed todebugdata(#8298) - The format of the
screenshot-thumbnailsscreenshots has changed. They are now a full image data URL. (#8299)

- red/orange/green color buckets for scores are tougher now. (#5831)
| Previously | Now | |
|---|---|---|
| Red (bad) | 0-44 | 0-49 |
| Orange (average) | 45-74 | 50-89 |
| Green (good) | 75-100 | 90-100 |
Scoring itself hasn't changed; only what color is used to decorate a score.

The chrome-launcher module is now on npm. Great for working with Chrome headless.
The Lighthouse Report Viewer can now view data from Lighthouse 2.x, including JSON saved from the CLI, exported from the Chrome extension or DevTools Audits panel. (#2521)
Thanks to Katie Hempenius, Artur M, Kevin Farrugia, Piper Chester, Robin Drexler, and Mike Deverell. Due to the effort of these developers we now have an audit for checking for paste-blocked password fields, unified usage of toLocaleString(), a correct gulp recipe, a well-functioning chrome-launcher module, and improved clarity in the audit test descriptions. We truly appreciate all these improvements!

This is a maintenance release on the stable 1.6 branch.
Master branch (tagged at 2.0.0-alpha) is under some heavy refactors, so we're holding off on shipping a new version. Expect one by mid-May. ( Poke around recent PRs and issues if you're curious what we're up to ;)
In the meantime, only a few changes here in 1.6.5:
- Improve HTTPS audit by using network records rather than Security domain, which is broken on Android.(original pr #1918) (#2054)
- Disable unused css rules audit for now, as we want to revisit correctness later (#1912)
- Add legend to decipher iconography left to us by the ancient ones (#1841)
- Print doesn't cut off expanded audit details (#1870)
- Biggin icons for a11y (#1856)
- Tweak report colors so that we are WCAG2AA valid.
- support multiple output modes (#1813)
- add update-notifier. (#1890)
- smokehouse: fix flakiness of dom-size expectation (#1881)
- include a normal CLI run in the travis build.
- remove npm prepublish (#1889)
Thanks to @ebidel and @paulirish for merging this stuff back to stable branch.
There were 44 PRs landed for this release. These are their stories.
Huge thanks to @sendilkumarn, who contributed four epic PRs. Also welcome to @tommycli, @narendrashetty, @mohsen1 and @dentemple. Readme tweaks are how it all starts. ;)

WebPageTest integration is in beta
By popular demand, you will soon have a way to run Lighthouse on demand in the cloud. We've worked closely with WebPageTest to enable Lighthouse auditing and analysis from within a WPT run. Our contribution WPO-Foundation/webpagetest#825 was just merged and Lighthouse on WPT is currently in private beta.
-
Lighthouse's CLI output has taken a chill pill - #1764
While you can view all Lighthouse results on the command line, it hasn't scaled well. A few screenworths of report was generally dumped to stdout right as Lighthouse finished up. Now, to keep your terminal happy, you will no longer see the reams of results printed to stdout. The HTML report is saved to disk by default, and you can automatically open it with
lighthouse --view.
If you still want the stdout output, use --output=pretty. Oh so pretty.
- CI coverage for Windows via AppVeyor - #1280
Thanks to a large effort from @XhmikosR, we now have an eye in the sky on Lighthouse's Windows compatibility. Now, all PRs are tested on both Linux and Windows.

Dropped support for Node earlier than v6 - #1519
Node v6 became the Node long-term-support version in October 2016. After a suitable mourning period for v4 with a
--harmonyflag, Lighthouse has moved on and will only support v6+ going forward. -
Improved selection of First Contentful and Meaningful Paint events from unusual traces - #1632, #1634
Lighthouse has banished the dreaded
-1score that has long plagued runs for certain sites.
First Meaningful Paint is now detected much more robustly. While it is not yet a completely solved problem, a large class of these errors should be eliminated. Reporting on these errors has also improved over the ambiguous
-1, clearly differentiating between an issue with Lighthouse and an issue with the page being tested. -
Open local report in online report Viewer - #1179
When viewing a Lighthouse HTML report generated locally—in the extension or from the command line—a new option is available in the "Export..." dropdown that allows you to upload to the Lighthouse Online Viewer.
You can then use the Viewer share button to get a report URL that you can share freely.
Behind the scenes, Viewer gets your permission via OAuth to create a GitHub secret gist and saves the report there. Since it's done as your gist, you maintain full control over the sharing of the report and you can delete it at any time. You can revoke the Viewer's permission to create gists under your GitHub settings.
-
Performance metrics are injected into trace saved with
--save-assetsfor viewing in timeline - #1446Lighthouse metrics like "First meaningful paint", "Time to Interactive", etc are mocked out as User Timing measures and injected back into the trace taken by Lighthouse.
If you save a run's trace with
--save-assetsand then open it in DevTools or Timeline Viewer, you'll be able to see your key metrics in context with the full trace of the page load. -
Throttling and emulation information in report - #1485, #1608, fc858ea
It's easy to forget what throttling and emulation settings were used for a particular Lighthouse run after some time has passed. The settings used are now saved in the raw JSON results and are printed at the top of the HTML report under the arrow dropdown.
-
UI to interactively block certain page resources and measure the load performance difference
The first version of the Performance Experiment project is landing in 1.5.0. When Lighthouse is run with the
--interactiveflag, a special report is generated that allows interactive selection of costly page resources. The experiment server then reruns Lighthouse on that page with those resources blocked.
This lets you experiment with your page load performance, interactively testing the effects of blocking or delaying assets in your critical path.

CSS usage - #1421, #1479, #1466, #1496, #1557
