From GroupScript documentation
Changes since 3.2.1
- Fixed a bug in e-mail queue using SMTP delivery
- Anti-spam field is shown for contact form
- Fixed Buy for friend option not working if the recipient was user who was not registered
- Added reCAPTCHA for "E-mail a friend" form to avoid spammers. This can be disabled in site settings.
- In some rare cases, when capturing credit card data failed, user would still receive an e-mail containing coupon code. This code would not show up anywhere in coupon export or admin, but still could make confusion.
