# Breaking: #98489 - Removal of SleepTask and TestTask {#breaking-98489-1664577935}

See [forge#98489](https://forge.typo3.org/issues/98489)

## Description {#description}

Previous TYPO3 installation contained the task `SleepTask` and `TestTask` which
served as examples when scheduler was introduced in 2009.

The tasks have been removed without substitution.

## Impact {#impact}

The scheduler tasks are not available anymore and won't be executed.

## Affected installations {#affected-installations}

All TYPO3 installations relying on these scheduler tasks.

## Migration {#migration}

If used, the tasks can be removed within the scheduler module.

The configuration `$GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['scheduler']['showSampleTasks']`
is removed automatically.
