David Coallier has a quick post to his blog today about a great change in the Text_CAPTCHA_Numeral PEAR package - its move to stable.

I have just made Text_CAPTCHA_Numeral go into stable state as it is not an overly complex package and it's simplicity is working very well.

Interface support is also included in the package (in "Text/CAPTCHA/Numeral/interfaces/NumeralInterface.php"). Check out the package's page on the PEAR website for more details and the downloads.
