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

[Akira Yokosawa]

Hi David and Frank,

After today's update (tlmgr update --all), which contains tools 71408,
I encountered build error in one of my documents with tabulary.

MWE:

-----------------------------
\documentclass{article}
%\RequirePackage{array}[=2023-11-01]
\usepackage{tabulary}

\begin{document}

\begin{tabulary}{6cm}{lLL}
  aaaa & bbbbb bbbbb & cccc cccc cccc cccc \\
\end{tabulary}

\end{document}
------------------------------

Log from pdflatex:

? 
-------------------------------

Workaround is to use RequirePackage{array}[=2023-11-01]
(shown as a comment in the MWE).

It looks to me like array v2.6 is a full rewrite using L3.
Would it be possible to make tabulary compatible with it?

Best Regards,

Akira
