Firstly, thanks to everyone for their help and suggestions. Sorry John= , I could not go back to an older version (homebrew). So I guess something = else has changed? Perhaps a fuller explanation might help:
What we are doing is extracting some YAML frontmatter metadata= into variables for a bash script. We use the following (simplified) comman= d
pandoc --lua-filter remove-meta-html.lua -f markdown+ya= ml_metadata_block  book-metadata-file.md --template meta-data.templ= ate  --to html -o file.tmp

remove-meta= -html.lua
function Pandoc(doc)
 for k,v in pairs(doc.= meta) do
  if v.t =3D=3D 'MetaBlocks' then
   for i,x = in ipairs(v) do
     if x.t =3D=3D 'Para' then v[i] =3D p= andoc.Plain(v[i].c) end
   end
  end
 end
=  return doc
end


The meta-data.templ= ate has lines like:
$if(volume)$BOOK_VOLUME=3D"$volume$"$endi= f$

We then read the variables from the created fil= e.tmp.

This has worked for some time, can any= one one see anything that would need to be corrected or could have changed = in recent versions?

One workaround is to use a Lua filter that
applies pandoc.utils.stringify to the contents of the
'volume' field in metadata.
