Java Edition:Vanishing Blocks
Vanishing blocks are blocks which 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.

Suspended String
When it was first added in 12w22a (a 1.3.1 snapshot) to 15w47c (a 1.9 snapshot) string could be "suspended" by placing it on non-solid blocks or air, but upgrading this string to 15w49a to 16w05b (1.9 snapshots) will delete it.[1]

Age 0/1 melon and pumpkin seeds placed in 15w35a and 15w35b (1.9 snapshots) will delete itself whenever reloaded.[2]
