Minecraft 1.19-pre2
Another 1.19 pre-release is out. See the changelog.
Warden
When the warden starts digging, it will force unmount off of any entity it is riding.
The warden can listen to the new teleport game event.
Teleport Game Event
The game will send the teleport game event from the destination of an enderman, shulker, or chorus fruit teleport. Players do not send the teleport game event when using an ender pearl, though any sensors nearby would detect the projectile_land game event first anyway. Players do not send the teleport game event when using a teleport command.
Tags
A new tag, worldgen/biome/mineshaft_blocking, was added that determines which bimoes block mineshafts from generating. It only contains the deep dark by default.
