 ## Next
 
+### New and Improved
+
+* Target aliases have been added: You can now create an alias for a target.
+  In most situations where you would use a target id, you can now instead use
+  the alias value. Crate an alias with 
+  `boundary aliases create target -value example.boundary -destination-id ttcp_1234567890`
+  and connect to a target using an alias using `boundary connect example.boundary`
+
 ### Added dependency
 
 * postgres citext dependency added to enable aliases to be globally unique
