Following is the enhancement introduced in this release:

Twilio SendGrid Authentication Method Changes

Conga Composer has enhanced the Twilio SendGrid integration settings section and made backend updates to support Twilio SendGrid's upcoming authentication changes from basic authentication, which required a username and a password, to using an API key. 

You must update your authentication method with Twilio SendGrid to API keys exclusively before SendGrid deactivates the functionality on December 9th, 2020 in order to ensure uninterrupted service and improve the security of your account
