- Deprecated Methods
  Method and Description
  com.google.appengine.api.datastore.Query.addFilter(String, Query.FilterOperator, Object) Use `Query.setFilter(Filter)`
  com.google.appengine.api.datastore.TransactionOptions.Builder.allowMultipleEntityGroups(boolean) Use `Builder.withDefaults().setXG(enable)` instead.

  com.google.appengine.api.images.ImagesService.getServingUrl(BlobKey) Replaced by `ImagesService.getServingUrl(ServingUrlOptions)`.
  com.google.appengine.api.images.ImagesService.getServingUrl(BlobKey, boolean) Replaced by `ImagesService.getServingUrl(ServingUrlOptions)`.
