Minecraft 1.7 Biomes Update - Preview
NOTICE: This is old information, but there are still things in here that are being implemented and will and could be in the new 1.7 update.
This should still work with 1.5
In this video I go through Notch's tweets from the last seven days and grab mainly 1.7 info along with a few other bits of informations. NOTE: Changed for 1.7 to 1.8 to 1.9 to 1.4.2
This video still has effective information regarding the 1.2.3 update which is the other half of the adventure update
