 - The binary of the package `cloud-sql-proxy` has changed from `cloud_sql_proxy` to `cloud-sql-proxy`.
 
+- The module `services.apache-kafka` was largely rewritten and has certain breaking changes. To be precise, this means that the following things have changed:
+
+  - Most settings have been migrated to [services.apache-kafka.settings](#opt-services.apache-kafka.settings).
+    - Care must be taken when adapting an existing cluster to these changes, see [](#module-services-apache-kafka-migrating-to-settings).
+  - By virtue of being less opinionated, it is now possible to use the module to run Apache Kafka in KRaft mode instead of Zookeeper mode.
+    - [A few options](#module-services-apache-kafka-kraft) have been added to assist in this mode.
+
 - Garage has been upgraded to 0.9.x. `services.garage.package` now needs to be explicitly set, so version upgrades can be done in a controlled fashion. For this, we expose `garage_x_y` attributes which can be set here.
 
 - `voms` and `xrootd` now moves the `$out/etc` content to the `$etc` output instead of `$out/etc.orig`, when input argument `externalEtc` is not `null`.
