Pack format

This feature is exclusive to Java Edition.
 

Pack format, sometimes referred to as pack version, is a number used in pack.mcmeta to describe what Java Edition versions a resource pack or data pack is compatible with. Each version specifies the pack formats it supports in its version.json. The pack format can be obtained by running /version, or using the F3 + V debug hotkey.

List of data pack formats
