「Microsoft Edge」v89.0.774.45On March 4th (local time), Microsoft released the latest stable (Stable) version of Microsoft Edge v89.0.774.45. New features, such as the hibernation Tab and Vertical Tab booted in Edge88, are enabled by default.
The hibernation tab (Sleeping Tabs) is a feature that actively releases inactive tab resources to reduce load. In the initial setup, the tag that has not been used for two hours is the target, and the title of the background tag for resource release (migration to sleep) becomes thinner.
スリープタブ（Sleeping Tabs）The company said that through this feature, memory usage in the general environment can be reduced by an average of 32% and CPU utilization can be reduced by 37% on average. In the system section of the setup screen (edge://settings/system), you can change the time before you transition to hibernation and manage the excluded site.

Another vertical tab is the ability to display the tab bar on the left panel, rather than on the bar at the top of the browse screen. You can easily turn it on / off with the icon in the upper-left corner of the screen, and it's easy to return to the familiar tab bar.
The advantage of vertical tags is that even if you open a lot of tags, it's easy to see the title. It is suitable for wide screen display and other environments with abundant horizontal display. Narrowing the display area of the content due to the width of the panel is disadvantageous, but if you fold it, you can switch to the Favicon display, so it won't be too much of a problem. The preview version of "Edge" also tested the ability to adjust the width of the tab panel with the mouse, and a stable version is expected to be introduced sooner or later.

When replacing the old and new "Edge", there are several points to pay attention to in the application of the "KioSque mode" mode, so the manager wants to use the transition file. In addition, a new administrative page (edge://compat) has been set up for browsing and editing the list of sites for "IE mode".
