v2.3.0

• The package name is changed from using an underscore (email_validator) to a dash (email-validator) to match PyPi's normalized package name.
• The library no longer checks that the local part is at most 64 characters because a more careful reading of RFC 5321 indicates the limit is optional and such email addresses have been found in the wild. However the check can be restored using a new strict=True parameter, and the overall 254 character email address length limit is still in place.
• New EmailSyntaxError messages are used for some exiting syntax errors related to @-sign homoglyphs and invalid characters in internationalized domains.
• When using allow_display_name=True, display names are now returned with Unicode NFC normalization.
• TypeError is now raised if something other than str (or bytes) is passed as the email address.
