tabulary doesn't work with array [2024/05/23 v2.6c]

[Akira Yokosawa]

David,

Thanks for the quick update!
It works with array v2.6c.

However, It doesn't work with array v2.5g.
My MWE with the RequirePackage enabled stops with:

------------------------
! Undefined control sequence.                                                   
\TY at box ...raybackslash \tyformat \insert at pcolumn                               
                                                  \@endpbox                     
l.9 \end{tabulary}                                                              
                                                                                
?                                                                               
! Emergency stop.
-------------------------

Is this intended?

Thanks, Akira
