(Developer and Platinum versions of the plugin)
Users can now prove they're human without having to solve a CAPTCHA. Instead, with just a single click, they'll confirm they are not a robot. reCAPTCHA replaces the plugin's original captcha module with Google reCAPTCHA, making the process easier and more intuitive.Documentation
