Microsoft is rolling out a new button option for the Edge toolbar.
Before this new button, to get to your browser history you had to press Control+H or find your History in the Edge menu.
Now Microsoft has added the option of adding a History button to your toolbar.
When clicked the new button brings up a floating panel with your history items.
From the panel, you can search your history and also delete history items.
You can also pin the panel to the side of your browser to have it permanently displayed.
The feature is currently in controlled rollout to the Canary and Dev versions of the Edge browser, and should come to mainstream users in a few weeks.
