• utilsScript option and loadUtils method now load the utils script using a dynamic import as opposed to injecting a new script tag.
• To make this work, the utils script (build/js/utils.js) is now an ES Module, which no longer uses any globals, like window.intlTelInputUtils (etc). This means it will no longer work to pre-load the utils script yourself, hence the new bundles (see next point).
• For those who are not worried about file size, we now provide two bundles which include the utils script: build/js/intlTelInputWithUtils.js and react/build/IntlTelInputWithUtils.js. If you're using ES Modules, you can import these as "intl-tel-input/intlTelInputWithUtils" and "intl-tel-input/reactWithUtils" respectively (TypeScript types included in the regular declaration files).
• New option validationNumberType which defaults to "MOBILE" - this determines the number type to enforce during validation with isValidNumber, as well as the number length to enforce with strictMode. This replaces the mobileOnly argument which you could previously pass to isValidNumber. (this change snuck in in v23.0.1 very quickly after releasing v23.0.0)
