The Twitter Blog has detailed a new version of the Twitter client for Android.

Push notifications are now present which allow you to be notified when someone interacts with you, e.g. @ replies you or DM’s you. To enable go to your account settings, select “automatic refresh” and choose to receive updates for Direct Messages, @Mentions (from the people you follow or anyone), and Tweets.

Multiple Accounts – something users have been crying out for, for some time. Now you can set-up multiple identities within the Twitter client and switch between profiles to check different groups of updates, and respond from the appropriate account.

You can download this updated version of Twitter for Android now from Android Market.
