 # Node Bing API
 Node.js lib for the Azure Bing Web Search API
 
+## Changelog v3
+Thanks to the contribution of @franciscofsales, version 3 supports the
+new API (Cognitive Services). This version is not compatible with the
+Azure version, so if you are still using an Azure access key, please
+stay with v2.
+
 ## Changelog v2
 In order to follow JavaScript best practices and allow the library to
 be promisified, the callback function is now the last parameter.
