+### Настройки cron задач
+
+В версии 4.4.5 добавлен функционал для изменения интервалов времени выполнения cron задач. 
+
+Для изменения интервала времени необходимо с помощью фильтра **retailcrm_add_cron_interval** добавить пользовательский интервал. Затем изменить интервал для cron задач с помощью фильтра **retailcrm_cron_schedules**.
+Кастомизацию необходимо добавить на сервере в директорию wp-content -> mu-plugins -> mu-simla.php. После добавления кастомизации в настройках модуля необходимо очистить старые cron задачи. 
+Перейдите в настройки, откройте "Отладочная информация" и нажмите на кнопку "Очистить cron задачи", появится окно с сообщением об успешной очистке, интервалы будут применены. 
+
+Если необходимо вернуть стандартные интервалы, то удаляем кастомизацию и в настройках так же очищаем старые cron задачи.
+
+**Интервалы по умолчанию:**
+```php
+[
+    'icml' => 'three_hours',
+    'history' => 'five_minutes',
+    'inventories' => 'fiveteen_minutes',
+]
+```
+> Важно! При использовании фильтра **retailcrm_cron_schedules**, можно использовать ключи: 'icml', 'history', 'inventories'.
+
+**Фильтры:**
+
+> retailcrm_add_cron_interval - позволяет добавить пользовательский интервал времени.
+
+> retailcrm_cron_schedules    - позволяет изменить интервал времени для cron задач. 
+
+**Пример использования:**
+```php
+<?php
+
+add_filter('retailcrm_add_cron_interval', 'add_cron_interval');
+
+function add_cron_interval($schedules)
+{
+    return ['two_minutes' => [
+        'interval' => 120, // seconds
+        'display'  => __('Every 2 minutes')
+        ]
+    ];
+}
+
+
+add_filter('retailcrm_cron_schedules', 'change_cron_tasks');
+
+function change_cron_tasks($cronTasks)
+{
+    $cronTasks['history'] = 'two_minutes';
+
+    return $cronTasks;
+}
+```
