- Возможность указать глубину автоопределения у _getField()
- Возможность использования фильтров в релейшенах: $oUser->getTopics(array('topic_date_add >' => '2011'));
- Удалены методы ModuleORM::GetByArray() и ModuleORM::GetCountByArray()
- Алиас для Sample_GetItemsByArrayKey(): Sample_GetItemsByKeyIn()
- Фикс автоопределения искомой сущности Sample_GetItemsByKey()
- Фикс Sample_GetAll() и Sample_GetAnotherSampleAll()
- В MapperORM вынесена обработка #order, #limit, #page в BuildFilterMore()
