Comparing changes: https://github.com/smarty-php/smarty/compare/v4.3.1...v4.4.1 It is noticeable that Smarty 4.3.1 does not officially support PHP 8.3. Is only supported with 4.4.0. Remark: During tests with Smarty 4.5.1, it was noticed that the following warning occurs: Deprecated: Using the unregistered function "function_exists" in a template is deprecated and will be removed in a future version. Use Smarty::registerPlugin to explicitly register a custom modifier. As of Smarty 5.X.X, templates must be revised again. The Smarty release 5.0.2 is already officially available. However, integration into FlatPress is not entirely trivial.

Escaping Smarty parsing
It is sometimes desirable or even necessary to have Smarty ignore sections it would otherwise parse. A classic example is embedding Javascript or CSS code in a template. The problem arises as those languages use the { and } characters which are also the default delimiters for Smarty.
Note
A good practice for avoiding escapement altogether is by separating your Javascript/CSS into their own files and use standard HTML methods to access them. This will also take advantage of browser script caching. When you need to embed Smarty variables/functions into your Javascript/CSS, then the following applies.
In Smarty templates, the { and } braces will be ignored so long as they
are surrounded by white space. This behavior can be disabled by setting
the Smarty class variable $auto_literal
to
false.
Examples
<script>
// the following braces are ignored by Smarty
// since they are surrounded by whitespace
function foobar {
alert('foobar!');
}
// this one will need literal escapement
{literal}
function bazzy {alert('foobar!');}
{/literal}
</script>
{literal}..{/literal}
blocks are used
for escaping blocks of template logic. You can also escape the braces
individually with
{ldelim}
, {rdelim}
tags or
{$smarty.ldelim}
,{$smarty.rdelim}
variables.
Smarty's default delimiters { and } cleanly represent presentational
content. However, if another set of delimiters suit your needs better,
you can change them with Smarty's
$left_delimiter
and
$right_delimiter
values.
Note
Changing delimiters affects ALL template syntax and escapement. Be sure to clear out cache and compiled files if you decide to change them.
<?php
$smarty->left_delimiter = '<!--{';
$smarty->right_delimiter = '}-->';
$smarty->assign('foo', 'bar');
$smarty->assign('name', 'Albert');
$smarty->display('example.tpl');
Where the template is:
Welcome <!--{$name}--> to Smarty
<script language="javascript">
var foo = <!--{$foo}-->;
function dosomething() {
alert("foo is " + foo);
}
dosomething();
</script>
