Vanishing blocks are blocks that disappear after an upgrade or downgrade. The game sets a block it doesn't recognize to air when loaded. After the block is set to air, no updates are given to neighboring blocks. The ability to set a block to air without causing updates is a versatile tool for discontinued block configurations.

April Fools' Blocks

Warning: April Fools' 

This feature requires the usage of April Fools' versions, often requiring file renaming or file deletion to load. See the help page for information on loading these versions.

2.0

In April Fools' version 2.0 (fork of 1.5.1), there were a few block that were added that could be applied to this method.

Block of Coal - A fake block of coal. Could be downgraded to versions before 2.0 as a vanishing block, but upgrading is slightly harder, as the fake coal block used a data value of 162, which will later become the Acacia Log, or Log2 in 13w43a (1.7.2 snapshot).
