-Release 25.0 (Unreleased)
--------------------------
-As announced
-`before <https://github.com/labgrid-project/labgrid/discussions/1467#discussioncomment-10314852>`_,
-this is the first release using `gRPC <https://grpc.io/>`_ instead of crossbar/autobahn for
-communication between client/exporter and coordinator.
-
-Crossbar/autobahn are unfortunately not very well maintained anymore. The
-crossbar component was moved to its own virtualenv to cope with the high number
-of dependencies leading to conflicts. Support for Python 3.13 is still not
-available in a crossbar release on PyPI.
-
-That's why labgrid moves to gRPC with this release. gRPC is a well maintained
-RPC framework with a lot of users. As a side effect, the message transfer is
-more performant and the import times are shorter.
-
-This is a **breaking change**. Version 25.0 exporters / coordinators / clients can
-not communicate with Version 24.0 and earlier exporters / coordinators / clients.

 Breaking changes in 25.0
 ~~~~~~~~~~~~~~~~~~~~~~~~
 Maintaining support for both crossbar/autobahn as well as gRPC in labgrid would
-be a lot of effort due to the different architectures of those frameworks.
-Therefore, a hard migration to gRPC is deemed the lesser issue.

+Therefore, hard migration to gRPC is required.

+Previously, the coordinator was running as a component started by the crossbar.
+Now, it is a standalone service which exposes a gRPC API directly.

+Due to the gRPC migration, 25.0 includes the following breaking changes:
 
-- The labgrid environment config option ``crossbar_url`` was renamed to
-  ``coordinator_address``. The environment variable ``LG_CROSSBAR`` was renamed
-  to ``LG_COORDINATOR``.
+- The labgrid environment config option ``crossbar_url`` was replaced by
+  ``coordinator_address``.
+  The environment variable ``LG_CROSSBAR`` was replaced by ``LG_COORDINATOR``.
 - The labgrid environment config option ``crossbar_realm`` is now obsolete as
   well as the environment variable ``LG_CROSSBAR_REALM``.
 - The coordinator is available as ``labgrid-coordinator`` (instead of
   ``crossbar start``). No additional configuration file is required.
 - The systemd services in ``contrib/systemd/`` were updated.
 
+To update your deployment to 25.0, you'll need to:
+
+- Update the coordinator, all clients and all exporters to the new release.
+- Start ``labgrid-coordinator`` directly (instead of via the crossbar
+  configuration file).
+  If needed, you can set the listening address using the ``--listen`` option.
+- Update any existing client and exporter configuration by replacing the
+  crossbar URL with the coordinator address.
+
 Other breaking changes include:
 
 - Support for Python 3.8 was dropped.
