-    The :func:`.transpile` function has been upgraded to internally convert 
-    `backend` inputs of type :class:`.BackendV1` to :class:`.BackendV2`, 
-    which allows the transpilation pipeline to now access the backend 
-    constraints through a :class:`.Target`. This change does not require any 
-    user action.
+    The :func:`.transpile` function has been upgraded to, in most cases,
+    internally convert transpiler constraints into a :class:`.Target` instance. 
+    If a `backend` input of type :class:`.BackendV1` is provided, it will be 
+    converted to :class:`.BackendV2` to expose its :class:`.Target` to the pass manager. 
+    This change does not require any user action.
