There are two new enhancements to the Contacts page:

Sort contacts by either first or last name

On the Contacts page, users can now sort contacts by last name, which is a more useful way to find and organize contacts. Previously, contacts were only sorted by first name. 

View only contacts that still require opt-in on the Contacts page

A new Show option on the Contacts page shows only the contacts that still need to opt-in to text messaging. This option includes contacts with a pending opt-in request and contacts who have never been sent an opt-in request. It is vital for compliance that contacts opt in to text messages prior to receiving communications, and this enhancement makes it easier to find contacts that haven’t yet completed this step.

To access the new option on the Contacts page, next to Show, click the down arrow and select Contacts Pending or Needing Opt-In.
