Hello everyone and welcome back to another episode of Front End News. It's been a fairly quiet week, but I do hope you will find the following topics both interesting and useful.
Lighthouse 6.1
We just got a significant update to Lighthouse. The most notable feature is that now the tool can use JS source maps to improve the unused-javascript audit.
Oh, and the labels now read as KiB instead of KB.
There are two new audits coming in:
-
long-tasksis a new diagnostic showing the longest main-thread-blocking tasks during load -
crawlable-anchorsis a new SEO audit that checks that anchors link to resolvable URLs
More changes can be found under the hood, including some new experimental features, updated dependencies, and more. The full release notes are available via the link below.
The new 6.1 version is scheduled to be available with the Chrome 86 update (scheduled for early October). That can be a long time to wait, so if you want to try the new features, you should download Chrome Canary which is currently being used to test-run version 86.

Interesting things worth having a look at
I also stumbled upon the following news items and I think they were way too interesting to be ignored, but they were also not fitting in the normal episode structure.
