-    - In the case of jobs with a single signer, it was previously possible to get the signer's redirect URL from `DirectJobResponse.getSingleRedirectUrl()`. This is now changed to `DirectJobResponse.getSingleSigner()` and you can [get the redirect URL](https://javadoc.io/static/no.digipost.signature/signature-api-client-java/6.1.1/no/digipost/signature/client/direct/DirectSignerResponse.html#getRedirectUrl()) from the returned single `DirectSigner` instance. The URL is represented as a [URI][java.net.URI] instead of previously being a `String`.

 ### Changes v6.1.x ➡️ v7.x
 
+If you are upgrading from an earlier version to v7.x, see also applicable previous section(s).
+
+- see the [Dependency](#dependency) section for how to properly declare your dependency using the BOM
+- see release notes for [v7.0.1][jakarta-support-release] for more details. Only the [configuration API](https://javadoc.io/static/no.digipost.signature/signature-api-client-java/7.0.4/no/digipost/signature/client/ClientConfiguration.Builder.html) has got some minor breaking changes:
+    - "globalSender" is renamed to [.defaultSender(Sender)](https://javadoc.io/static/no.digipost.signature/signature-api-client-java/7.0.4/no/digipost/signature/client/ClientConfiguration.Builder.html#defaultSender(no.digipost.signature.client.core.Sender))
+    - "serviceUri" and "trustStore" has been combined and replaced with [ServiceEnvironment](https://javadoc.io/static/no.digipost.signature/signature-api-client-java/7.0.4/no/digipost/signature/client/ServiceEnvironment.html). Instead of separately specifying the former two, instead specify either `ServiceEnvironment.STAGING` or `ServiceEnvironment.PRODUCTION` depending on which environment you intend to use.
