+
+feature: the key of a credential store may be a path of keys, so stores of several kinds share one object of config.json.
+
+- `CredentialStore.key` is a key of `config.json` or a path of keys separated by dots, such as
+  `connections.pg`; read, validate, write and `credentialValues` use the list at that path, and a
+  write creates the objects of the path that are missing and keeps their other keys.
+
 ## 0.2.1
 
 fix: a credential store holds credentials of one kind, without a kind field in its entries, and the dialog edits several stores in tabs.
