In this release, we made three changes:

1. Updated ESM C tokenizer to no longer depend on ESM3. So now you can use ESM C without having to accept the ESM3 license.
2. Updated the transformer class so it returns hidden states.
3. Pined transformers version to be <4.47.0 to prevent a tokenizer issue. If you are currently seeing tokenizer issues, try reinstalling the new release.
