1.6 snapshot!

i just tried out the new 1.6 snapshot.
it was awesome! simple to get (just google "1.6 snapshot download mac/PC"), fun and fast with little lag. plus all my maps, worlds and survers where there to! my issue is that all the survers are unable to connect because thay are on 1.5.
over all i love the snapshot.
now i would live to clear up some things.
1: the sky island biome is a lie and does not real
2: horses are tamed with 64 apples. yes 64.
3: horse saddles are not yet craftable yet.
4: when a zombie is burning in the day he will spawn minions form the sky.
5: the only new mobs are the horse and the donkey.
6: you can put a chest on a donkey but you can't open them
7: the snapshot is only part of what is to come, its just to show what they have done.
