# Deprecation: #80000 - InlineOverrideChildTca

See [forge#80000](https://forge.typo3.org/issues/80000)

## Description

These `TCA` `type=inline` properties have been deprecated and superseded with the more
general property `overrideChildTca`:

-   foreign_types
-   foreign_selector_fieldTcaOverride
-   foreign_record_defaults

## Impact

It is now possible to override display (FormEngine) related columns properties and the types section of
child `TCA` from within the parent `TCA`. This is also allowed in a
parents `['types']['columnsOverrides']` section.

## Affected Installations

Instances using one of the above inline properties should adapt to the new `overrideChildTca` property.

## Migration

A `TCA` auto-migration is in place. It will transfer the old settings to the new property as
shown below and logs deprecation entries if there is no `overrideChildTca` defined. This allows extension
authors to keep both the old and the new settings to support CMS v7 and v8 at the same time without
having deprecations logged.
