  1. Format Versions

Most Addon files contain a format_version field, often in the description. Here is an example:

BP/entities/dragon.json

{
  "format_version": "1.13.0",
  "minecraft:entity": {
    "description": {
      "identifier": "wiki:dragon",
      "is_spawnable": false,
      "is_summonable": true,
      "is_experimental": false
    }
  }
}

Format versions exist so that Mojang can add new functionality into the Addon system without breaking old addons. In the example above, the format version is 1.13.0. This means that the entity will be processed using the 1.13.0 entity mechanics.

When you pick a format version to use, you are tying that file to a specific version. You cannot use new components or functionality
