gantt.config.auto_scheduling_compatibility = true;

### Details

:::

The [time constraints functionality](guides/auto-scheduling.md#timeconstraintsfortasks) was introduced in v6.1 to improve the auto scheduling logic of Gantt. 
The **auto_scheduling_compatibility** config was added to [provide backward compatibility with previous versions](guides/auto-scheduling.md#version-compatibility).
