Yesterday, Microsoft Edge v87 was rolled out with only a few new features and fixes, but with a lot of excitement about the future releases.

As it is, the new Edge version isn’t spectacular, but the release notes rather insist on the long-awaited tools that should improve on memory and battery usage.

What to expect from Edge v87?

Edge users now get dark theme support to sidebar Search, but also for new Kiosk Mode features like idle timeout and automatic download deletion (via management policy).

If you’re a Mac user, installing the latest Safari version shouldn’t cause Edge to crash anymore.

Some PDF features have also been updated, along with improving behavior for PDF loading and display.

Indeed, the developers have been working on a collection of features, called sleeping tabs, which are not available for general use yet.

Who can enable Sleeping Tabs?

According to internal testing, Sleeping Tabs should reduce memory usage by 26%, and CPU usage by 29%. This is going to be an improvement, considering that Edge is a rather demanding browser.

Besides accessibility to developers, the feature is also available in the Canary version, but not for every user.

To test it, you have to install Edge Canary and enable the experimental flags called Sleeping Tabs in edge://flags menu. To turn them off, you have to toggle the option in edge://settings/system.

The feature is currently undergoing deployment, so it will take some time before it’s going to be available for general use.
