Previous version of WPDirectory Pro have a security vulnerability. To read about the vulnerability, please head over to the WPDirectory Pro Forums. You’ll also be able to find there everything included with this release, including the addition of reCAPTCHA.

Other updates were scheduled to be release for version 1.6.0 but were pushed back due to the XSS vulnerability found. We can expect those updates to be in the next release, but no offical time has been given on when that will be.

I must say that, in my opinion, WPDirectory Pro is quickly becoming the best Link Directory plugin for Wordpress. It started out as a plugin with limited features, and due to the hard work of Bruce ( WPDirectory Pro Owner ) and his programmer, its morphing into a full fledge Link Directory at an outstanding price.
