There is a new {function} {/function} block tag.
This allows to reuse code sequences like a function.
It can call itself recursively.





New {foreach} syntax to loop over an array:
{foreach $myarray as $var} .... {/foreach}
$var@key will deliver the key
$var@iteration will deliver the iteration
$var@index will deliver the index
$var@total will deliver the total number of array entries
$var@first will deliver true for the first iteration
$var@last will deliver true for the last iteration





New assign
{$foo = myfunct( ($x+$y)*3 )} as function parameter





$foo_{$bar} variable name containing other variable





-- Delimiters surrounded by whitespace are no longer treated as Smarty tags.
Therefore, { foo } will not compile as a tag, you must use {foo}. This change
Makes Javascript/CSS easier to work with, eliminating the need for {literal}.
