Does something happen with columns?

Hi guys,
I just updated project and noticed that now

->columnSpanFull()

->columnSpanFull()

is not working correctly for me anymore. When I change it to

->columnSpan('full')

->columnSpan('full')

it is working correctly. Should I replace it in the entire codebase or it is just a bug?
