Patch 8 has hit the Diablo III beta and aside from introducing the new BattleTags feature, it brings significant changes to the monk and does a wipe on previous characters and achievements.

Diablo III Beta Patch 8 – v.0.5.0.8059

General

Battle.net BattleTags are now live! To learn more about BattleTags and how to set up yours today, check out the official FAQ (http://us.battle.net/d3/en/blog/4132437). Please note that in order to log into the Diablo III beta, you must create a BattleTag via Account Management.
Due to a change in the way we store character data, all characters have been wiped. Please note that this wipe will also affect gold, achievements, followers, and artisans.
Achievements have been temporarily disabled and will not be available again until a future patch. During this time, characters will be unable to earn new achievements or complete any additional objectives of achievements in progress.
Players will now see recommended items for their active character when accessing the auction house Search tab.
