+
+Removed support for deprecated publisher auth configuration within the `scaffolder` configuration block, such as `scaffolder.github.token`. Access should instead be configured through `integrations` configuration.
+
+For example, replace the following configuration in `app-config.yaml`
+
+```yaml
+scaffolder:
+  github:
+    token: my-token
+```
+
+with
+
+```yaml
+integrations:
+  github:
+    - host: github.com
+      token: my-token
+```
