# Breaking: #82832 - Use at daemon dropped from scheduler

See [forge#82832](https://forge.typo3.org/issues/82832)

## Description

The functionality to execute tasks via the unix "at daemon" (atd)
has been dropped.

The following method has been dropped:

-   `TYPO3\CMS\Scheduler\Scheduler->scheduleNextSchedulerRunUsingAtDaemon()`

## Impact

If this feature has been used, existing tasks may not be executed anymore.

## Affected Installations

The feature "useAtdaemon" had to be explicitly enabled in scheduler
extension configuration. In general it was very sparsely used.

## Migration

Switch to cron execution instead.
