** Removed all "empty" loot entries.
** Most items with damage had their average durability increased.

'''[[Minecraft:Respawn]]ing'''
* Changed how respawn positions are chosen for [[Minecraft:bed]]s and [[Minecraft:respawn anchor]]s.

** Respawning players now face the block they respawned at.
** Placing players onto dangerous blocks is now avoided when possible.

** Minor grammatical changes were made.
*** Changed "This pack was made for a newer version of Minecraft and may {{fc||#FFAAAA|no longer}} work correctly." to "This pack was made for a newer version of Minecraft and may {{fc||#AAFFAA|not}} work correctly." (<code>pack.incompatible.confirm.new</code>).

'''[[Minecraft:Tag]]s'''
* Entries can now be marked as optional using <code>"required": false</code>.
** For example, <code>values: ["#minecraft:beds", "minecraft:stone"]</code> allows all [[Minecraft:bed]]s and [[Minecraft:stone]] in the tag. This can also be written as <code>values: [{id: "#minecraft:beds", "required": true}, {id: "minecraft:stone", "required": true}]</code>.{{verify|type=change|edition=java}} Setting <code>"required"</code> to <code>false</code> makes either entry optional.
