 To use Java-based callbacks, create one or more beans that implement `Callback`.
 Any such beans are automatically registered with `Flyway`.
 They can be ordered by using `@Order` or by implementing `Ordered`.
-Beans that implement the deprecated `FlywayCallback` interface can also be detected, however they cannot be used alongside `Callback` beans.
 
 By default, Flyway autowires the (`@Primary`) `DataSource` in your context and uses that for migrations.
 If you like to use a different `DataSource`, you can create one and mark its `@Bean` as `@FlywayDataSource`.
