Hello everyone, I’m excited to announce a brand new major version of fclabels. This library provides first class labels that can act as bidirectional record fields. The labels are implemented as lenses. This new version contains some interesting new features like support for polymorphic updates and lens derivation for GADTs. Furthermore the API has been cleanup significantly and should be easier to work with.
