• fb:time now supports internationalization and behaves as times across the rest of Facebook. Note that in the en_US local, this means that dates will now have (time) and (date) switched from the old implementation. October 6, 2007 1:27am is now 1:27am October 6th, 2007, which is more consistent with standard Facebook dates.

• Fixes a bug that was introduced as part of the first fix. In the past, we've not thrown any exceptions when the template data passed to feed.publishUserAction mapped 'images' to the empty array, but now it does. We should be able to handle an array of length 0, so now we do again.
• bug 3508

• Previously, when calling the user preference API functions, you needed a valid user session. The user whose preferences you were accessing was derived from the session key. Now, you can call the preference functions without a user session by passing the optional $uid parameter. This lets you access user preferences for users even when they are not using your app. (If you don't pass a $uid parameter, the session key will be used to get the target user.) The affected functions are data.setUserPreference, data.setUserPreferences, data.getUserPreference and data.getUserPreferences.
