Rails - Oct 2012 - SyntaxError in Posts#index ?

For some reason getting this...  Any ideas?

Extracted source (around line *#13*):

10: 			<%= link_to "Show", post %> |
11: 			<span class="admin">
12: 				<%= link_to "Edit", edit_post_path(post) %> |
13: 				<%= link_to "Delete", post, method: :delete, data:
{confirm: "Are you sure?"} %> |
14: 			</span>
15: 			<div>
16: 	</div>

Ok, looked at the rails guides.  Aparently the syntax is different from the 
tutorial I''m following.. they use

<%= link_to ''Remove'', book, :confirm => ''Are
you sure?'', :method => :delete
%>


How can I be sure to use the correct syntax in the future and know what 
changes have happened?  I tried finding the notation at 
http://api.rubyonrails.org/ .. but failed.  Possibly because I don''t
know
how to use it.

The trick is to make sure that you are using the version of rails that
the tutorial expects.  Make sure the tutorial is for rails 3.n you
will be wasting time if it is a rails 2 tutorial you are following.
railstutorial.org is good and is free to use online.
