After looking around the forum and at the mechanics changes for magic on this server I have become curious as to what has become of the spell focus and greater spell focus feats. This and this make reference to them being changed, sorta. But what exactly are the modifications, if any?

The changes that have been made are listed on the mechanics changes, anything else may eventually be changed but is sort of up in the air. That's the best answer I can give at this time.
