 ## Summary
 
-This breaking release removes deprecated compatibility modules and symbols, and implicit enum conversions.
+<!-- Here goes a general summary of what this release is about -->
 
 ## Upgrading
 
-> [!NOTE]
-> We recommend upgrading first to v0.3.8 and remove all deprecation warnings (and implicit conversions of enum values to protobuf messages) before upgrading to v0.4.0.
->
-> By doing so you'll be guided by the deprecation warnings and when you are done, upgrading to v0.4.0 should imply not extra work.
-
-* Passing enum values directly to build protobuf messages is not longer supported, you need to call the conversion functions `xxx_(from|to)_proto_v1alpha8()` explicitly.
-* Replace `frequenz.client.common.metric.Metric` with `frequenz.client.common.metrics.Metric`.
-* Replace `frequenz.client.common.microgrid.components` imports with `frequenz.client.common.microgrid.electrical_components` imports.
-* Replace `frequenz.client.common.enum_proto.enum_from_proto` with `frequenz.client.common.proto.enum_from_proto`.
-* Replace `frequenz.client.common.metrics.proto` conversion imports with `frequenz.client.common.metrics.proto.v1alpha8` imports.
-* Replace `PaginationInfo.from_proto()`, `PaginationInfo.to_proto()`, and `PaginationInfo.to_proto_v1alpha8()` with `frequenz.client.common.pagination.proto.v1alpha8` conversion functions.
-* Replace `frequenz.client.common.pagination.Info` with `frequenz.client.common.pagination.PaginationInfo`.
-* Use API-provided `v1alpha8` pagination protobuf messages directly instead of `frequenz.client.common.pagination.Params`.
