+'@backstage/config': patch
+---
+
+Adds an optional type to `config.get` & `config.getOptional`. This avoids the need for casting. For example:
+
+```ts
+const config = useApi(configApiRef);
+
+const myConfig = config.get<SomeTypeDefinition>('myPlugin.complexConfig');
+// vs
+const myConfig config.get('myPlugin.complexConfig') as SomeTypeDefinition;
+```
