Update Minecraft 1.8.1, it's a small update, released on 24 November 2014 year and will fix a lot of errors and bugs introduced in previous update 1.8.
The only new feature introduced in this update, this new game rule doEntityDrops. Its action is comparable to the rule action doMobDrops, but acts only on the entity. Also, have added some changes to the gameplay and interface of the game. In the credits there are two new name: Ryan Holtz (TheMogMiner) and Searge. The subject of the Lamp Jack began to call upon the iron and snow Golems. Were changed some colors on the map. Monsters no longer run away from the creeper. Improved performance, performed multiple optimizations and improvements. Also, was slightly changed interface.
In the 1.8.1 update we have fixed many of the errors introduced in 1.8. The entire list of fixes includes more than a few dozen points. Were the imperfections of the graphics and interface, the incorrect operation of some commands, bugs server side, and improper operation of some items and potions. Now players will no longer deal with the fact that the monsters fall through the ground, falling blocks do not have animation or with what the foal looks indistinguishable from an adult horse or zombie rider rides not on the chicken, and inside it. Also, fixed a bug with the fact that iron Golems attack the creeper, causing large-scale destruction of the game world, without any involvement of the player.
I can safely say that with the release of Minecraft update 1.8.1, the game became much more stable than before.
