We’re currently in the process of preparing the next beta patch for release. As part of this patch, we’ll be wiping all characters and items (including those placed on the auction house).
 
While a specific ETA is unavailable at this time, please note that Beta Patch 5 may go live as early as tomorrow afternoon.

General
All characters have been wiped. As part of this process, artisans, gold, and items (including those placed on the auction house or in a shared stash) have also been reset.
 
Switching out class skills will now require the use of a new feature known as the Nephalem Altar. Nephalem Altars are currently located in New Tristram, as well as in key locations throughout Act I. Clicking on an altar will open up the skill UI, allowing both active and passive skills to be selected or exchanged.
 
Quests
Gold rewarded from quests has been significantly reduced.
 
Experience rewarded from quests after level 4 is now based on the number of mobs you’d have to kill to earn the same amount of experience, rather than being a strict percentage of a level
