Formless 3 has been released and is available in the psc-0.14.7-20220303 package set.
This release entirely rewrites the library into a single file. It removes many rough edges from Formless 2 (no more spec, no more proxies, no more unwrapping & wrapping newtypes, no more Initial type class, no more injAction or injQuery, no more Validation type), and gives you much more control over validation and handling events that arise from the Formless component. Most importantly, you can now run validation within the context of your form component’s HalogenM directly, which means your validation functions have full access to the component state including all the form fields.
