 ## Unreleased
 
+* Add getSessionId helper method to fetch the current sessionId.
+* Add support for append user property operation.
 * Add tracking of each user's initial_referrer property (which is captured as a set once operation). Referrer property captured once per user session.
 
+## 2.7.0 (December 1, 2015)
+
+* If cookies are disabled by user, then fallback to localstorage to save the cookie data.
+* Migrate sessionId, lastEventTime, eventId, identifyId, and sequenceNumber to cookie storage to support sessions across different subdomains.
+
 ## 2.6.2 (November 17, 2015)
 
 * Fix bug where response code is not passed to XDomainRequest callback (affects IE versions 10 and lower).

+5. `append`: this will append a value or values to a user property. If the user property does not have a value set yet, it will be initialized to an empty list before the new values are appended. If the user property has an existing value and it is not a list, it will be converted into a list with the new value appended.

 Note: if a user property is used in multiple operations on the same `Identify` object, only the first operation will be saved, and the rest will be ignored. In this example, only the set operation will be saved, and the add and unset will be ignored:
