The water swiming bug was fixed ! Thank god ! (Download Minecraft here)

There were two important new problems in the 1.4.3 pre-release that we had to fix, so here’s a pre-release of 1.4.4 instead! We hope to publish it in the launcher in the middle of next week.

Another 20 or so issues fixed, full list here: 1.4.4 issue list
Fixed the “unable to swim upwards” bug (prevented a 1.4.3 official release)

Download : Minecraft Snapshot 12w40a

We’re now fully into the “prepare for release” mode, so we’ve almost only worked on bug fixing and performance. We’ve decided to aim for October 24 for the full Pretty Scary Update. Here’s this week’s changelog:
Minor terrain additions for the witch
Flatworld configuration now allows you to generate trees, strongholds etc
A number of new NBT tags for items (intended for custom map makers)
The pick block action now works on items
Pressing the 1-9 hotkeys while hovering over an item will put that item into the inventory bar
The left-click action will no longer open doors, pull levers, push buttons or open trapdoors. Use the right mouse button!
Firespread has been slightly nerfed again to prevent infinitely spreading fires
More bugfixes & tweaks!

MAP : Download The Kaizo Caverns - Super Hostile 04

This map is a network of linked underground caverns. The map takes place entirely underground, and the whole thing is wrapped in a giant cube of bedrock (no escape!) This was the first map of the series where I introduced the Victory Monument goal system. To me, it has a very "Super Metroid" or "Castlevania: Symphony of the Night" feel to it.

SNAPSHOT : Minecraft 12w19a

It’s time for the weekly snapshot. We are continuing on the work to separate the client from the server, and have fixed a bunch of stuff related to that transition. We’ve also,
Added cocoa plants to jungles
Added a “large biomes” world type
Added specific names for the different sandstone and smooth stone block 

Get the snapshot here:
Client: http://assets.minecraft.net/12w19a/minecraft.zip* (See below!)
Server: http://assets.minecraft.net/12w19a/minecraft_server.jar (or EXE) 

* The client now comes with both the client-side and the server-side JAR files. The file called “minecraft.jar” should be in your “.minecraft/bin” folder as usual, and the “minecraft_server.jar” file should be in a folder called “.minecraft/server”.
