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) command
pandoc --lua-filter remove-meta-html.lua -f markdown+yaml_metadata_block book-metadata-file.md --template meta-data.template --to html -o file.tmp
remove-meta-html.lua
function Pandoc(doc)
for k,v in pairs(doc.meta) do
if v.t == 'MetaBlocks' then
for i,x in ipairs(v) do
if x.t == 'Para' then v[i] = pandoc.Plain(v[i].c) end
end
end
end
return doc
end
The meta-data.template has lines like:
$if(volume)$BOOK_VOLUME="$volume$"$endif$
We then read the variables from the created file.tmp.
This has worked for some time, can anyone one see anything that would need to be corrected or could have changed in recent versions?

Or if needed use single quotes around the value to protect punctuation marks, noting that to include a single quote in a YAML single-quoted string you use two single quotes, as in `'don''t'`.
One workaround is to use a Lua filter that
applies pandoc.utils.stringify to the contents of the
'volume' field in metadata.
