+  [#2069](https://github.com/ory/kratos/issues/2069):
+
+  This PR introduces the upstream OIDC query parameters `login_hint` and `hd`.
+
+  To send additional upstream parameters the form can post this on a login,
+  registration or settings link submit. For example the form below does an OIDC
+  flow to Google. We can now add additional parameters such as `login_hint` and
+  `hd` to the upstream request to Google login with a pre-filled email
+  `email@example.com`:
+
+  ```html
+  <form action="https://kratos/self-service/login?flow=">
+    <input type="submit" name="provider" value="google" />
+    <input
+      type="hidden"
+      name="upstream_parameters.login_hint"
+      value="email@example.com"
+    />
+    <input type="hidden" name="upstream_parameters.hd" value="example.com" />
+  </form>
+  ```
