# Breaking: #98069 - DebugConsole removed {#breaking-98069-1659536025}

See [forge#98069](https://forge.typo3.org/issues/98069)

## Description {#description}

The DebugConsole comes from ExtJS times and was triggered when e.g. a request
failed to give a developer its response, including the stacktrace. Nowadays,
browsers offer a console allowing to investigate requests. Also, PHP debuggers
(e.g. xdebug) are commonly known and used, which makes the DebugConsole obsolete.

## Impact {#impact}

Triggering the DebugConsole is not possible anymore. Also, the PHP method
`\TYPO3\CMS\Core\Utility\DebugUtility::debug()` always renders the plain
debug output to the client.

The 3rd argument `$group` of the method
`\TYPO3\CMS\Core\Utility\DebugUtility::debug()` is removed.

## Affected installations {#affected-installations}
