WC_Cache_Helper::delete_version_transients() │ public static │ WC 2.3.10

Устарела с версии 3.6.0 Adjusted transient usage to include versions within the transient values, making this cleanup obsolete.. Больше не поддерживается и может быть удалена. Рекомендуется заменить эту функцию на аналог.

When the transient version increases, this is used to remove all past transients to avoid filling the DB.

Note; this only works on transients appended with the transient version, and when object caching is not being used.
