Which version of CB Connect to Use?

My project has surpassed it's expected finish time and thus my membership at Joomlapolis. I was just wondering... I have 2 versions of CB Connect that I can use. I have a regular download of version 6.0.5 and I have a beta version (plug_cbconnect_7.0.0-beta.4+656b99275.zip). Any suggestion whether it's safe to use 7.0 since it was still in beta back then? Or if I will lose any potent functionality if I use the non-beta?

DON'T USE THE BETA!!! I just installed it this morning since I couldn't get the other one to work correctly (the documentation is like 5 years old, by the way). It completely broke the website (500 errors all around). Did a site restore and will deal with the old version 6.

CB Connect 7.x Beta works perfectly fine on CB 2.x. The documentation for it is found directly below and includes full up to date step by step configuration instructions.

Most likely you're having errors due to a bug in CB it self which causes plugin fields to always prefix with cb_, which they should not. This causes CB Connect to be missing is fields (well not missing, but wrongly named so it doesn't find what it's looking for). This is fixed by installing latest CB 2.x nightly then reinstalling CB Connect 7.x Beta.

I don't know what the issue is. I just can't get it to pull the email address from Facebook. There is no special permissions for that. If I put [profile_email] in for the 'username format' field, it does not work. It gets some 15 digit number and puts that in for the profile. I know that's the field I'm looking for because if I put [provider_name] into it, the username is 'Facebook'.

If I put anything into the 'fields' area (from -> to), it just breaks the signin completely. For example, I've tried putting from 'Email' to 'username' it says 'signup with facebook failed: error please enter a username'.

No matter what I do, it always says, signup incomplete please enter email address.
