Microsoft.XRM.SDK.dll upgrade

Hi All,

I have one small doubt regarding Microsoft.Xrm.SDK.dll. Recently i received an email from Microsoft saying they are turning off support for any Microsoft.Xrm.Sdk.dll version less than 8.2.  

I am using Dynamics CRM 2016 (App version: 8.1.1.1183, DB Version: 8.1.1.1183),  and sdk client to connect to this CRM. This sdk client uses Microsoft.Xrm.Sdk.dll v6.1.

I want to know will it continue to work or i have to make change in the code and upgrade the dll?

Thanks
