We previously 
announced on this blog about renaming Status enumeration values in reports for removed objects from 
DELETED to 
REMOVED. To keep the rest of the API consistent, we are also renaming the 
isDeleted method in 
Campaign and 
AdGroup objects to 
isRemoved. The 
isDeleted method is marked as deprecated, and will continue working until 
November 30, 2014. To ensure that your scripts continue to work properly, make sure you fix your scripts to use the new method before 
November 30, 2014.
If you have questions about this change, let us know on our 
forum. You can also provide feedback via the 
Google Ads Developers Google+ page.
