 ## Upgrading
 
-- `grpclib` was removed, if you used `grpclib` you should switch to `grpcio` instead.
-
-  You should also update your dependency to `frequenz-client-base` (without any `[grpclib]` or `[grpcio]` suffix).
-
-- The `parse_grpc_uri` function (and `BaseApiClient` constructor) now enables SSL by default (`ssl=false` should be passed to disable it).
-
-- The `parse_grpc_uri` and `BaseApiClient` function now accepts a set of defaults to use when the URI does not specify a value for a given option.
+<!-- Here goes notes on how to upgrade from previous versions, including deprecations and what they should be replaced with -->
 
 ## New Features
 
-- The connection URI can now have a few new SSL options:
-
-  * `ssl_root_certificates_path` to specify the path to the root certificates file.
-  * `ssl_private_key_path` to specify the path to the private key file.
-  * `ssl_certificate_chain_path` to specify the path to the certificate chain file.
+<!-- Here goes the main new features and examples or instructions on how to use them -->
