This week, Mojang has begun the long process of separating the server logic from the client. They hope to make it easier to add features in the game going foward - essentially not having to program in game additions twice, for two functionally different "Minecrafts" - and also to make it possible for players to invite their friends to play on their local computer without setting up a server. While the intent to begin migrating was announced in the past, this Snapshot begins taking the first step into realizing it fully. Note - the changes are NOT complete, but the game should run normally.
Now, on to the changelog:
More fixes to silk touch and block picking
Wooden tools work in furnaces
Villagers spawned from spawning eggs will get a random profession
Updated language files
The download links are slightly different than prior Snapshots - the link below is the client ZIP, not JAR; it contains both client-side and server-side JAR files. The Server JAR link is as it has been for previous Snapshots.
Client ZIP: [url='http://mcf.li/JtsrdC']Download[/url] (This is a ZIP file containing client- and server-side JAR files)
Server JAR: [url='http://mcf.li/IIJUCG[/url]Download[/url]
Enjoy this first glance into some very exciting changes!
