Is there any way you guys could consider using this newer version as it would really be great to get rid of having to use another social sharer plug in.
That's on our plans. You can follow our progress in this ticket:
http://plugins.trac.wordpress.org/ticket/1817
is there any way to add the Facebook recommendation bar in your plug in
Are you referring to this Recommandations feature?
https://developers.facebook.com/docs/reference/plugins/recommendations/
If so, I'd be happy to create a new ticket to log your suggestion, and we'll consider it for a future Jetpack update!
