There seems to be something changed in tex4ht. I am using TL 2025, installed
fresh one week ago on new Linux
In longtable, with p columns, and use array package in order to do custom
column specification. I noticed that now tex4ht no longer keeps the new lines
in the cell. It basically cloppers all content of the cell together, which
makes it very hard to read.
This did not used to be like this before, else I would have noticed it. This
seems to be recent change?
Here is MWE
----------------------
\documentclass[12pt]{book}
\usepackage{longtable}
\usepackage{array} % Required for custom column specifications
\begin{document}
\begin{longtable}[c]{|>{\footnotesize}p{1in}|p{3in}|p{.5in}|>{\small}p{.7in}|>{\small}p{.7in}|}\hline
date/time & summary of changes & {\footnotesize number problems} &
{\footnotesize not solved} & {\footnotesize solved but not verified} \\\hline

&20,151&
1046\newline
5.198\%
& NA \\ \hline
\end{longtable}
\end{document}
---------------
Compiling with lualatex gives this

Compiling with
make4ht -ulm default -a debug foo.tex "mathjax,htm"
gives

Notice how all the new lines are ignores in the HTML.
Now, if I remove the array package and remove all the |> from table columns
specs. then now it works OK.

Now lualatex gives same as before, but tex4ht now gives

How to make tex4ht not lose the newlines in p columns?
Thanks
