It isn´t as straight forward to add this column as I thought. If I add it 
after "Version" then the following fields are not aligned anymore, even tough 
they use some kind of identifier – but that identifier also doesn´t match the 
row title. After reading about mediawiki syntax I came to the conclusion that 
I need to add the new column in every data row as well and cannot just assign 
values to the rows and leave out whats not known yet.

! Feature !! Version !! Description !! Notes
{{FeatureMerged
|name=scrub
|version=3.0
|text=Read all data and verify checksums, repair if possible.
}}
