Fraenkiman e544ed6d9a Smatry Release 4.4.1 on Feb-2024 
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.
