-# Upgrading from an older version
-
-## Upgrading from v3 to v4
-
-Smarty 4 is mostly identical to Smarty 3. Most notably, it adds support for PHP8 and drops support for PHP7.0 and below.
-Additionally, some deprecated features that have long been discouraged have been dropped from the language.
-
-### Muting PHP8 warnings
-If you simultaneously upgrade Smarty to v4 van PHP to v8, you may notice your error logs filling up with warnings about undefined or null template vars
-due to a change in how PHP handles these. This may be helpful to spot errors, but if you find this annoying, you can use
-`$smarty->muteUndefinedOrNullWarnings()` to make Smarty convert these warnings into notices.
-
-### ASP tags
-You can no longer user ASP-style tags like `<% %>` and `<%= %>` in your templates.
-Replace them with `{...}` tags.
-
-### SmartyBC
-Check your codebase for `SmartyBC`.
-We have dropped deprecated API calls that where only accessible through the SmartyBC class.
-
-### No more embedded PHP
-We have completely dropped support for `{php}` and `{include_php}` tags and embedded PHP in templates.
-Check your templates for this, and rewrite any embedded PHP blocks, by moving logic to your PHP files or by
-creating a [plugin function](./programmers/plugins/plugins-functions.md).
-
-### Other changes
-
-Search your code for the following changes:
-
-- `SMARTY_RESOURCE_CHAR_SET` and `SMARTY_RESOURCE_DATE_FORMAT` constants have been removed
-- `Smarty::muteExpectedErrors` and `Smarty::unmuteExpectedErrors` API methods have been removed
-- `Smarty::getVariable` method has been removed. Use [Smarty::getTemplateVars](programmers/api-functions/api-get-template-vars.md) instead.
-- [Smarty::registerResource](programmers/api-functions/api-register-resource.md) no longer accepts an array of callback functions
