### Added
- Added support for PHP8.2
- Added a new way to extend Smarty functionality using `Smarty::addExtension()` or `Smarty::setExtensions()`. Please see the docs for more information.
- Custom tags can accept positional parameters, so you can write a block compiler that support this: `{trans "Jack" "dull boy"}All work and no play makes %s a %s.{/trans}` [#164](https://github.com/smarty-php/smarty/issues/164)

- Full support for null coalescing operator: `{$var ?? $value_if_null}` [#882](https://github.com/smarty-php/smarty/issues/882)

### Changed
- All Smarty code is now in the \Smarty namespace. For simple use-cases, you only need to add
  `use \Smarty\Smarty;` to your script and everything will work. If you extend Smarty or use
  Smarty plug-ins, please review your code to see if they assume specific class or method names.
  E.g.: `Smarty_Internal_Template` is now `\Smarty\Template\`, `SmartyException` is now `\Smarty\Exception`.
- Template variable scope bubbling has been simplified and made more consistent. 
  The global scope now equals the Smarty scope in order to avoid global state side effects. Please read
  the documentation for more details.
- Lexers and Parsers PHP files are reliably generated from sources (.y and .plex) using the make file 
- Smarty now always runs in multibyte mode, using `symfony/polyfill-mbstring` if required. Please use the
  multibyte extension for optimal performance.
- Smarty no longer calls `mb_internal_encoding()` and doesn't check for deprecated `mbstring.func_overload` ini directive [#480](https://github.com/smarty-php/smarty/issues/480)
- Generated `<script>` tags lo longer have deprecated `type="text/javascript"` or `language="Javascript"` attributes [#815](https://github.com/smarty-php/smarty/issues/815)
- Smarty will throw a compiler exception instead of silently ignoring a modifier on a function call, like this: `{include|dot:"x-template-id" file="included.dot.tpl"}` [#526](https://github.com/smarty-php/smarty/issues/526) 
- The documentation was largely rewritten

### Deprecated
- `$smarty->getPluginsDir()`
- `$smarty->loadFilter()`
- `$smarty->setPluginsDir()`
- `$smarty->assignGlobal()`
- Using `$smarty->registerFilter()` for registering variable filters will trigger a notice.

### Removed
- Dropped support for PHP7.1
- Removed `$smarty->left_delimiter` and `$smarty->right_delimiter`, use `$smarty->getLeftDelimiter()`/`$smarty->setLeftDelimiter()` and `$smarty->getRightDelimiter()`/`$smarty->setRightDelimiter()`
- Removed support for the `$cache_attrs` parameter for registered plugins
- Removed support for undocumented `{make_nocache}` tag
- Removed support for deprecated `{insert}` tag, the 'insert' plugin type and the associated $smarty->trusted_dir variable
- Removed the undocumented `{block_parent}` and `{parent}` alternatives to `{$smarty.block.parent}`
- Removed the undocumented `{block_child}` and `{child}` alternatives to `{$smarty.block.child}`
- Removed support for loading config files into a non-local scope using `{config_load}` from a template 
- Removed `$smarty->autoload_filters` in favor of `$smarty->registerFilter()`
- Removed `$smarty->trusted_dir` and `$smarty->allow_php_templates` since support for executing php scripts from templates has been dropped  
- Removed `$smarty->php_functions` and `$smarty->php_modifiers`. 
- You can no longer use native PHP-functions or userland functions in your templates without registering them. If you need a function in your templates,
  register it first.
- Removed support for `$smarty->getTags()`
- Removed the abandoned `$smarty->direct_access_security` setting
- Dropped support for `$smarty->plugins_dir` and `$smarty->use_include_path`. If you must, use `$smarty->addPluginsDir()` instead,
  but it's better to use Smarty::addExtension() to add an extension or Smarty::registerPlugin to
  quickly register a plugin using a callback function.
- Removed constants such as SMARTY_DIR to prevent global side effects.
- Removed direct access to `$smarty->template_dir`. Use `$smarty->setTemplateDir()`.
- Removed direct access to `$smarty->cache_dir`. Use `$smarty->setCacheDir()`.
- Removed direct access to `$smarty->compile_dir`. Use `$smarty->setCompileDir()`.
- Removed `$smarty->loadPlugin()`, use `$smarty->registerPlugin()` instead.
- Removed `$smarty->appendByRef()` and `$smarty->assignByRef()`.
- Removed `$smarty->_current_file`
- Removed `$smarty->allow_ambiguous_resources` (ambiguous resources handlers should still work)
