Is www.facebook.com/share info for doing a Share Button compatible with old and new JS SDK?

I heard of yet another way to do the share button, which is on

http://www.facebook.com/share/

It include this Javascript file:

<script src="http://static.ak.fbcdn.net/connect.p开发者_JAVA技巧hp/js/FB.Share" type="text/javascript"></script>

Is it compatible with the old and new Facebook Javascript SDK too?

The share functionality is part of the old Javascript SDK. The share functionality is being deprecated and replaced with the "like" functionality. I would not recommend using a share on a site that also uses the new Javascript SDK.

From facebook on http://developers.facebook.com/docs/share:

"We don't recommend the Share button for new developers. If you aren't already using the Share button, we recommend you use the Like button and Open Graph protocol instead of Share for sharing pages from your website. The Like button is simpler to user and is the recommended solution moving forward."
