+### Added Support for Tomcat 10
+
+This version supports all the necessary building-block modules for our users to use `camunda-bpm-platform` community and enterprise editions in conjunction with `Tomcat 10.1`.
+
+{{< note title="Heads-up!" class="warning" >}}
+`Tomcat 10` is compatible with the `jakarta` namespace. 
+If you wish to use it, the `jakarta` modules needs to be used (`camunda-webapp-tomcat-jakarta`, `camunda-engine-rest-jakarta`).

+
+* Replace Java EE class references (`javax.*`) with Jakarta class references (`jakarta.*`)
+* You might have a look at [`org.eclipse.transformer:transformer-maven-plugin`](https://github.com/eclipse/transformer)
+* Replace Camunda class references:
+* `org.camunda.bpm.application.impl.EjbProcessApplication` → `org.camunda.bpm.application.impl.JakartaEjbProcessApplication`
+* `org.camunda.bpm.application.impl.ServletProcessApplicationDeployer` → `org.camunda.bpm.application.impl.JakartaServletProcessApplicationDeployer`
