order emails

-- HikaShop version -- : latest
-- Joomla version -- : 3.x

Hi guys,

I am trying to correct my order emails and I removed all my modifications and noticed that the email design is very different now with code such as
<!--{IF:BILLING_ADDRESS}--><td>{VAR:BILLING_ADDRESS}</td><!--{ENDIF:BILLING_ADDRESS}-->
<!--{IF:SHIPPING}--><!--{IF:SHIPPING_ADDRESS}--><td>{VAR:SHIPPING_ADDRESS}</td><!--{ENDIF:SHIPPING_ADDRESS}--><!--{ENDIF:SHIPPING}-->.

Where has all the php code gone and what should i be doing to make my order emails work like yours do now?

Please note that by using the code above everything is working. I'm just interested to learn more.
