+  Starting from version 0.15, when the GPG backend is used the encrypted
+  credentials are stored in the $XDG_STATE_HOME/oama directory.
+  If the XDG_STATE_HOME environment variable is not set then it defaults to
+  $HOME/.local/state.
+
+  That is a breaking change! If you use the GPG backend you need to manually
+  move your credential ~/.local/var/oama/*.oama files into the new directory.
