+###### What's new
+- The insight data schema for orders has changed. Configurable and bundle products no longer output as separate line items; instead, parent data is used to augment child products.
+- Simple products in order sync were commonly showing price 0 - we're now looking up parent prices for these where possible.  
+- We've added _parent_id_ to catalog insight data schema. 
+- We have deprecated some of our External Dynamic Content URLs. We've added notes on how to replace these in your campaigns.
+
+###### Bug fixes
+- We've fixed an error with updating products following an order sync - an exception was thrown once all available orders had been synced.
