-## Use the version 3.1 of the send API
+## New !! Version 3.1.0 of the Nodejs wrapper !
+
+This version modifies the way to construct the Client or the calls. We add the possibility to add an array with parameters on both Client creation and API call (please, note that each of these parameters are preset and are not mandatory in the creation or the call) :
+
+Properties of the $settings (Client constructor) and $options (API call function)
+
+url (Default: api.mailjet.com) : domain name of the API
+version (Default: v3) : API version (only working for Mailjet API V3 +)
+perform_api_call (Default: true) : turns on(true) / off the call to the API
+secured (Default: true) : turns on(true) / off the use of 'https'
