This list will is an overview of all possible improvements for v 4.0. I'll try to give some order, details will be specified in separate tickets as specified in the boxteam slack

1. change cbvalidation settings to module style like all newer modules.

2. translations for all default messages in en,es,de,fr,nl (and more?). Name language resource `cbvalidation`

3. specify your own language resource to override the defaults, which means: add your own resource named `cbvalidation_custom` or something simular.

4. different way to specify custom messages for more flexibility and same syntax for global and local customizations

5. option to specify a translation for the fieldname itself, so it can be used in a localized message.

6. values array to specify translations for special values in localized messages

7. ordered validation rules per field

8. bail option

9. simpler syntax to specify rules (and options to keep more advanced syntax)

10. replace (or add simpler syntax for type validator)

11. better validators for unique

12. more validators, like file upload, ipv4, ipv6 and more.
