Fences are decorative wooden wall blocks added in the Seecret Friday update 8. They count as one and a half blocks tall for player collision, and one block tall for all other purposes. They cannot be jumped over from the same level as the fence but can have other blocks placed on top of them. A fence occupies the center space of blocks and automatically connects to one another when another fence is placed next to it. Fences are one of the many blocks that are broken more quickly with a sword, but deals double damage to it.
Standing on top of a fence in multiplayer counts as an illegal move, and can cause players to get stuck. This action may also crash the server. This has been confirmed as a bug and has been fixed in the Beta 1.3 update[citation needed], which is due to be released on the 22nd February 2011.
Despite being made of wood, fences are not flammable (will not disappear due to fire). However, placing fences near lava will result in fire blocks appearing as the lava attempts to burn it.
Uses
A fence's primary use is enclosing an area, to keep ouside mobs and players out, inside mobs and players in, or both. A wide area can be made monster-proof by enclosing it in fences and lighting the inside portion heavily. This keeps any monsters from spawning within the fence, and keeps any monsters which spawned outside the fence from coming in, though spiders can jump over the fence and skeletons can shoot over it.
Fences can also be used as railings, especially on the edges of balconies or floating platforms. Since fences cannot be jumped over, this keeps players and mobs from falling off while still allowing them to easily see past the fence.
If a grassy area is fenced in and lit, during the night a large amount of passive mobs will spawn within the fence. This can be used to quickly collect a large amount of drops such as wool or raw porkchops. Additional blocks can be placed along the outside perimeter of the fence, allowing mobs to enter the pasture, but making them unable to leave.
Fence corners do not need to be complete in order to be sealed. A corner where two directions meet at a right angle can be created without the actual corner piece. This will create two separate fences which terminate next to each other without actually touching. While there is a visible gap, players and mobs will still be unable to pass through. This feature can be used to create lengths of diagonal fences, which will appear as nothing but posts, yet will still prevent anything from passing.
Stacking

Multiple fences can be stacked on top of each other by creating a wall of blocks one layer shorter than the intended height of the fence and working down. Removing blocks from underneath the fence doesn't cause it to collapse like cacti and doors, so the lower layers of the wall can one-by-one be replaced by fences easily. This allows the players to make thin pillars or chandeliers to seemingly support floating blocks for decoration purposes.

Future Plans
There may be plans to add a gate, which would most likely be placed like a fence, and fit aesthetically with other fence pieces. However, it would act like a door, where you would click it to open it. Doors work fine as a substitution, but they just look out of place between fence posts. This topic is most recognized at this thread on Getsatisfaction.com, where Notch himself commented saying "Hmmm... Possibly! Why not?"
