 ### Changelog for internal API (ui-api)
 
+### 6.0.0 
+
+Removed `password` from responses to operations which require them. This is for two reasons, 
+
+- Consistency between how rulesets operate and how manual processing works. A rule can `Approve` but require the actual password to be stored in the clef storage. 
+With this change, the same stored password can be used even if rulesets are not enabled, but storage is. 
+- It also removes the usability-shortcut that a UI might otherwise want to implement; remembering passwords. Since we now will not require the 
+password on every `Approve`, there's no need for the UI to cache it locally. 
+  - In a future update, we'll likely add `clef_storePassword` to the internal API, so the user can store it via his UI (currently only CLI works). 
+
+Affected datatypes:
+- `SignTxResponse`
+- `SignDataResponse`
+- `NewAccountResponse`
+
+If `clef` requires a password, the `OnInputRequired` will be used to collect it. 
+
