The Main Features -
New Mob - Wolves! This is the most exiting part of the update in my opinion as you can tame them by Feeding them(right clicking on them) with a random amount of bones from 2+ and when you tame them they follow you and when you attack something they also attack them, their spawn is quite rare but once you have tamed them they are quite amazing.
New features - Achievements and Stats - This is also quite exiting as it adds an aim to the game the achievements wont be like chores and they will be exiting goals Notch said - they will be exiting different things like, ride a pig off a cliff.
The stats will keep a record of different things such as how many tree's cut down, amount of Blocks broken, how far down you have dug and time played plus much more...
- The rest of the patch is just a few bug fixes and stuff nothing too interesting
The patch overall is quite exiting and the release date hasn't been confirmed yet but it is rumored that it could be 28/3 or 3/4.
Thanks for reading
