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.

Extending Smarty With Plugins

Table of contents

Version 2.0 introduced the plugin architecture that is used for almost all the customizable functionality of Smarty. This includes:

  • functions

  • modifiers

  • block functions

  • compiler functions

  • prefilters

  • postfilters

  • outputfilters

  • resources

  • inserts

With the exception of resources, backwards compatibility with the old way of registering handler functions via register_* API is preserved. If you did not use the API but instead modified the class variables $custom_funcs, $custom_mods, and other ones directly, then you will need to adjust your scripts to either use the API or convert your custom functionality into plugins.
