Breaking Change
Default email
validator has been made stricter to disallow leading, trailing and consecutive dots in local part of email addresses.
If this new behaviour does not meet your requirements you will need to use a regex
validator or create a custom email address validator for use on the relevant fields instead.
The full new regular expression used is as follows:
/^(?!.*\.\.)[a-z0-9_%+-](?:[a-z0-9._%+-]*[a-z0-9_%+-])?@([a-z0-9]+([a-z0-9-]*[a-z0-9]+)?\.)+[a-z]{2,6}$/i
