Hi there,

Are there any plans to update this module for compatibility with Zend Framework 3 at all ? The Zend_Captcha module references this and when you try to pull it down via composer it fails due to version requirements.

Thanks

Google launched a new ReCaptcha api version 2, but the actual is still working (don't know for how long). I have all set for a PR (already using on the development of a new project) but I need some insights.

There are some changes that would generate some backward incompatibilities. So either we create a ReCaptcha2.php and the developer can specify which one or a 3.0 version. and the dev specify in the composer configuration (2 or 3)

Since ZF2 uses this for it's ReCaptcha form helper (form/view), it needs to be changed too (i have it's PR ready too).

If we create a ReCaptcha2.php here, we need it on ZF2 too and when creating the captcha you can specify \Zend\Captcha\ReCaptcha or \Zend\Captcha\ReCaptcha2 (BC ok).

If we use a version 3.0 here, to try to maintain BC, the ZF2 form and view helpers should try to detect the version installed and use it.

Not sure the best approach here ... Any thoughs?

Regards,
Leandro
