With snapshot 24w45a, Minecraft now allows you to assemble two separate models into one item. This is showcase of how you can use that by showing the bow with its arrow separated to give it depth. While the item texture remains the same, the bow model held in your hand changes even if it's held in your off hand or viewed in third person.
The latest version of the pack should be compatible with any version after snapshot 24w45a, but the pack will only be updated to remove the "made for an older version" marker with each full update release.
