+These changes aims to add:
+- A brand-new omnichannel contact profile
+- The ability to communicate with known contacts only
+- Communicate with verified contacts only
+- Merge verified contacts across different channels
+- Block contact channels
+- Resolve conflicting contact information when registered via different channels
+- An advanced contact center filters
