    Версія Опис
    8.4.0 Тепер параметр dba має бути примірником Dba\Connection. раніше очікувався дійсний dba resource.
    8.3.0 Calling dba_fetch() with dba as the 3rd argument is now deprecated.
    8.2.0 dba_fetch()'s optional skip argument is now at the end in line with PHP userland semantics. The previously overloaded signature is still accepted but discouraged.
