Fence Gate

The Fence Gate, first mentioned on Get Satisfaction then confirmed by Jeb on Twitter will be one of the many new additions to Beta 1.8, also known as "The Adventure Update".

Fence gates will be in the PAX Prime version of the adventure update.

Fence gates are only opened by right-clicking (unlike doors and trapdoors, which can be opened by left- or right-clicking) and are not affected by redstone.
