# Breaking: #91066 - Move interfaces of Dashboard {#breaking-91066}

See [forge#91066](https://forge.typo3.org/issues/91066)

## Description {#description}

The interfaces of the dashboard have been moved out of the
interfaces folder to be consistent with the overall TYPO3 structure.

## Impact {#impact}

New widget types that have implemented one or more of the interfaces of EXT:dashboard.
If the namespace of those interfaces is not changed, you will get errors saying
that the interfaces are not found anymore.

## Affected Installations {#affected-installations}

All 3rd party extensions that created own widget types and implement one of the
interfaces of EXT:dashboard should update their paths. The accepted interfaces
are:

-   `AdditionalCssInterface`
-   `AdditionalJavascriptInterface`
-   `ButtonProviderInterface`
-   `ChartDataProviderInterface`
-   `EventDataProviderInterface`
-   `ListDataProviderInterface`
-   `NumberWithIconDataProviderInterface`
-   `RequireJsModuleInterface`
-   `WidgetConfigurationInterface`
-   `WidgetInterface`

## Migration {#migration}

The interfaces listed above have been moved from `\TYPO3\CMS\Dashboard\Widgets\Interfaces`
to `\TYPO3\CMS\Dashboard\Widgets`. You need to adapt the namespaces of those
interfaces in your own widgets.
