 ## Summary
 
-This release focus on improving the config management, but also introduces other minor improvements and fixes an important bug.
+<!-- Here goes a general summary of what this release is about -->
 
 ## Upgrading
 
-- The `ConfigManagingActor` now takes multiple configuration files as input, and the argument was renamed from `config_file` to `config_files`. If you are using this actor, please update your code. For example:
-
-   ```python
-   # Old
-   actor = ConfigManagingActor(config_file="config.toml")
-   # New
-   actor = ConfigManagingActor(config_files=["config.toml"])
-   ```
-
-- The `MovingWindow` now take all arguments as keyword-only to avoid mistakes.
-- The `frequenz-quantities` dependency was bumped to `1.0.0rc3`.
-- The `ComponentMetricsRequest` now produces a channel name without the `start_date` if the `start_date` is `None`. If you are somehow relying on the old behavior, please update your code.
+<!-- Here goes notes on how to upgrade from previous versions, including deprecations and what they should be replaced with -->
 
 ## New Features
 
-- The `ConfigManagingActor` can now take multiple configuration files as input, allowing to override default configurations with custom configurations.
-- A new `frequenz.sdk.config.load_config()` function is available to load configurations using `marshmallow_dataclass`es with correct type hints.
-- Implement and standardize logging configuration with the following changes:
-   * Add `LoggerConfig` and `LoggingConfig` to standardize logging configuration.
-   * Create `LoggingConfigUpdater` to handle runtime config updates.
-   * Support individual log level settings for each module.
+<!-- Here goes the main new features and examples or instructions on how to use them -->
