For those of you using custom themes, the new liking ability requires a small change to your theme. You must replace the comments block in your theme ({block:Comments}) with the new responses block ({block:Responses}). With most themes, this is a simple switch, and in many cases, you can replace the entire comments block with {block:Responses /}.

For further cleanup, you should remove any instances of {block:Fans}...{/block:Fans}, {block:Favorite /}, and {FavoriteCount}, as these elements are now deprecated.

We have also changed {CommentCount} and {CommentCountPluralized} to {ResponseCount} and {ResponseCountPlurlized}. You can use these new elements anywhere inside {block:Posts} (they used to only work inside {block:Comments}).
