Bing search has added a dropdown menu to restrict your search to certain dates. The last option on this menu is to put in your own date but for some reason it defaults to ten days ago. This adds in a "Past year" entry after the "Past month" and before the custom date.
On Chrome if you change pick one of the other options (like "Past week" or something) then the Past Year entry disappears. On Firefox it stays though. I can't figure out how to make it stay on Chrome so I thought I might as well release this update
