 # Changelog
 
+## [1.0.0](https://github.com/wuespace/telestion-core/compare/v0.9.0...v1.0.0) (2024-09-05)
+
+
+### ⚠ BREAKING CHANGES
+
+* **api:** `DecodedMessage` was renamed to `ResponseMessageWrapper`
+* **api:** Remove the second constructor from `TelestionVerticle` that allowed to skip loading loading the default config (`public TelestionVerticle(boolean skipDefaultConfigLoading)`)
+* **api:** Improve the method naming: In the `TelestionVerticle`, `getGenericConfig()` is now called `getUntypedConfig()`
+* **api:** Improve the method naming In the `TelestionVerticle`, `getGenericDefaultConfig()` is now called `getUntypedDefaultConfig()`
+* **api:** Move `Class<T> getConfigType()` in `TelestionVerticle` to `Class<T> VerticleConfigStrategy.getConfigType(Class<X extends TelestionVerticle<T>> clazz)`
+* **api:** Remove `defaultStorageKey` method in `WithSharedData` interface.
+* **api:** Rename method `get` to `getString` in `HeaderInformation` class.
+* **api:** Rename `JsonMessage` interface to `JsonRecord`.
+* **api:** Remove `GenericConfiguration` class. Use `UntypedConfiguration` to indicate generic, untyped configuration or `NoConfiguration` to indicate no configuration options instead. To build your own typed configuration options, implement `TelestionConfiguration`.
+* **api:** Remove `Config` class in favor of `TelestionVerticle`
+* Remove `Configuration` and `VerticleConfig` from services module and add them to the application module.
+* **services:** Remove `ConfigurableApplication` because it implements the same behaviour as the `Telestion` class in the application module, and is not used at the moment.
+* **application:** Remove the `Application` class from the application module because it is empty
+* **config:** The deprecated `config.json` is no longer available
+
