## Remove deprecated BaseApplication and CLI classes
- PR: https://github.com/joomla/joomla-cms/pull/42884
- Files: `libraries/src/Application/BaseApplication.php`, `libraries/src/Application/CLI.php`
- Description: These legacy classes have been removed.
Use `\Joomla\CMS\Application\ConsoleApplication` or framework equivalents instead.
**(more detail needed: migration examples)**

## Move JPATH_PLATFORM constant to compat plugin
- PR: https://github.com/joomla/joomla-cms/pull/44638
- Description: The `JPATH_PLATFORM` constant is no longer globally defined.
It is only available if the Backward Compatibility plugin is enabled.
Extensions should avoid using this constant.
**(more detail needed: code examples and alternatives)**

## Remove fetchExtensionCompatibility in UpdateController
- PR: https://github.com/joomla/joomla-cms/pull/45436
- File: `administrator/components/com_installer/src/Controller/UpdateController.php`
- Description: The `fetchExtensionCompatibility` method has been removed.
Extensions or scripts that called this method will break and need to be updated to use the new update handling logic.
**(more detail needed: replacement approach)**

## Extend versioning, save related information in history table and restore historical data
- PR: https://github.com/joomla/joomla-cms/pull/45515
- Description: The versioning system now stores additional related data in the history table.
Restoring historical versions also restores linked metadata.
Extensions interacting with `#__ucm_history` may require schema or API updates.
**(more detail needed: schema differences and migration examples)**
