Will https://www.facebook.com/dialog/oauth API call be valid after OAuth2 migration?

I am desperately looking for an answer to the following question that was also asked on the Forums by bromo http://forum.developers.facebook.net/viewtopic.php?id=106817 .

What is the difference between what we are currently using

https://www.facebook.com/dialog/oauth?client_id=XXXXXXXX&redirect_uri=YYYYYYY

and what now appears in the documentation

https://graph.facebook.com/oauth/authorize?client_id=XXXXXXXX&redirect_uri=YYYYYYY

I cannot find any reference in Facebook docs about "https://www.facebook.com/dialog/oauth" being still valid or if it will be deprecated with Oauth2 m开发者_如何学Cigration.

Thanks Dave
