The main idea has been to simplify the validation process on the client-side by flattening errors output. To achieve such
a goal, the whole validation process has been rewritten (and luckily for us, much simplified). This will be a breaking change and will be released as 1.0.
PR implements DetailedValidationError which inherits from ValidationError and can keep position in lists nested forms. The form will return a linear list of errors instead of a nested dictionary.

This release has been inspired by Problem Details for HTTP APIs - RFC7807 and blog post Structuring validation errors in REST APIs written by @k3nn7.
