Last week we mentioned that Starbucks was looking to add Passbook support to its iOS app by the end of September. Well, they missed the target by a few days, but this evening Starbucks released an update to its iPhone app that includes, among other things, the long-awaited Passbook support. Here's the full changelog:

• Passbook support
• iOS6 support
• Now easier to sign up and start earning Rewards with our new account creation flow
• Accessibility, data optimization, and performance improvements
• Multiple bug fixes

When setting up Passbook for Starbucks, you can select different Starbucks locations that you want to set as your favorites. This will allow Passbook to pull up your Starbucks card upon arrival, without you having to go looking for it.
