Breaking: #82832 - Use at daemon dropped from scheduler

See Issue #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.
