Fence Gate

The Fence Gate, as confirmed by Jeb on Twitter will be one of the many new additions to Beta 1.8, also known as "The Adventure Update". The item will likely behave similarly to a door (or more specifically a half-door), in the matter that it opens when clicked on. A fence gate would most likely match the style of the fence, so if they choose, players don't have to use doors with fences (which some people find unappealing).

According to Jeb, fence gates will be in the PAX Prime version of the adventure update.
