What's the 3 best updates in minecraft pe?

Well I think 0.12.1 is first place it adds nether and sprinting and crouching and lots more!
0.13.1 would be next but sadly all it did was add desert biomes and redstone.
0.10.5 is 2nd place with new blocks new flowers and more!
0.9.1 Adds villagers and lots of new stuff! (Including better graphics and minecarts)
0.4.1 and 0.13.1 are 4rth
