# Deprecation: #86270 - config.tx_extbase.objects and plugin.tx\_%plugin%.objects

See [forge#86270](https://forge.typo3.org/issues/86270)

## Description

The `config.tx_extbase.objects` and `plugin.tx_%plugin%.objects` configuration options
have been marked as deprecated.

## Impact

Configuring class overrides using `config.tx_extbase.objects` or `plugin.tx_%plugin%.objects`
will trigger a PHP `E_USER_DEPRECATED` error.

## Affected Installations

All installations that make use of the TypoScript `config.tx_extbase.objects` or `plugin.tx_%plugin%.objects`
configuration options are affected.

## Migration

Use XCLASSes configured in `ext_localconf.php` using
`$GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects']`.

Register implementations in the Extbase object container instead if you need to override classes
that are processed by the `PropertyMapper` like domain models or if you rely on additional
injections:

```php
GeneralUtility::makeInstance(\TYPO3\CMS\Extbase\Object\Container\Container::class)
    ->registerImplementation(Base::class, Override::class);
```

If you conditionally configured `config.tx_extbase.objects` or
`plugin.tx_%plugin%.objects`, then move that conditional logic into the
overriding class itself.
