+- Support for Carbon 3 added #483
 
 ### Breaking changes
 - `Folder::getStatus()` no longer returns the results of `EXAMINE` but `STATUS` instead. If you want to use `EXAMINE` you can use the `Folder::examine()` method instead.
-
+- `ClientManager::class` has now longer access to all configs. Config handling has been moved to its own class `Config::class`. If you want to access the config you can use the retriever method `::getConfig()` instead. Example: `$client->getConfig()` or `$message->getConfig()`, etc.
+- `ClientManager::get` isn't available anymore. Use the regular config accessor instead. Example: `$cm->getConfig()`
+- `M̀essage::getConfig()` now returns the client configuration instead of the fetching options configuration. Please use `$message->getOptions()` instead.
+- `Attachment::getConfig()` now returns the client configuration instead of the fetching options configuration. Please use `$attachment->getOptions()` instead.
+- `Header::getConfig()` now returns the client configuration instead of the fetching options configuration. Please use `$header->getOptions()` instead.
+- `M̀essage::setConfig` now expects the client configuration instead of the fetching options configuration. Please use `$message->setOptions` instead.
+- `Attachment::setConfig` now expects the client configuration instead of the fetching options configuration. Please use `$attachment->setOptions` instead.
+- `Header::setConfig` now expects the client configuration instead of the fetching options configuration. Please use `$header->setOptions` instead.
+- All protocol constructors now require a `Config::class` instance 
+- The `Client::class` constructors now require a `Config::class` instance 
+- The `Part::class` constructors now require a `Config::class` instance 
+- The `Header::class` constructors now require a `Config::class` instance 
+- The `Message::fromFile` method now requires a `Config::class` instance 
+- The `Message::fromString` method now requires a `Config::class` instance 
+- The `Message::boot` method now requires a `Config::class` instance
