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.
