## Breaking Changes & Deprecations
- By deprecating, we indicate that we will stop maintaining such models, but there is no intention of actually removing those models and breaking support for them (they might one day move into a separate repo/on the Hub, but we would still add the necessary imports to make sure backward compatibility stays). The main point is that we stop testing those models. The usage of the models drives this choice and aims to ease the burden on our CI so that it may be used to focus on more critical aspects of the library.
- Breaking changes ### Default optimizer in the `Trainer` class
