Version 2.1 of the Drupal reCAPTCHA module has been released and includes a number of enhancements.
Update: Version 2.2 fixes some minor things...
- Support for the updated Captcha 3.0 RC1 API - The new API is much cleaner, and features a number of usability enhancements
- Multiple theme support - Change the look of the reCAPTCHA form to either White, Red or Black Glass (more coming soon)
- Separation of the reCAPTCHA Mailhide - Having Mailhide held in the reCAPTCHA module meant that in order to use the input filter, you were required to have the Captcha module enabled. Now you don't have to have the captcha module in order to use reCAPTCHA Mailhide.
