Would using the v3 embed link be an issue? (instead of v2)

[ONg]

The embed for a form is as such:

<script charset="utf-8" type="text/javascript" src="//js.hsforms.net/forms/embed/v2.js"></script>
<script>
  hbspt.forms.create({
    region: "na1",
    portalId: "xxxxx",
    formId: "xxxxx"
  });
</script>

... Just wondering instead of using //js.hsforms.net/forms/embed/v2.js, would using //js.hsforms.net/forms/embed/v3.js be ok?

Context: We embedded the form with no issues as an iframe, but we need it as a raw HTML form instead. After switching it to a HTML form, the captcha on the form stopped working. 

Stumbled upon this post: https://community.hubspot.com/t5/APIs-Integrations/Forms-Api-Captcha-Handling/m-p/248800 ... tried the v3 link and it worked properly. Contacted Hubspot Support to see if it's a viable solution, and they told me to ask the question here instead so here I am.

Would this v3 link be okay?
