+## Release and Upgrade Notes
+
+The release 7.0.0 of the `awx.awx` collection is intended to be identical
+to the content prior to the migration, aside from changes necessary to
+have it function as a collection.
+
+The following notes are changes that may require changes to playbooks.
+
+ - Specifying `inputs` or `injectors` as strings in the
+   `tower_credential_type` module is no longer supported. Provide as dictionaries instead.
+
 ## Running
 
 To use this collection, the "old" tower-cli needs to be installed
