Still pretty important and relevant given there's no seamless option as Mmark for math rendering according to reports (1, 2), it's still best one can get. Also nice and important to not break compatibility leaving many user's files broken or stuck in an old hugo version.

No further info besides #7023 (comment) and that people seem to support this request.

Did this change go through? I've just noticed all the block-level attributes I had for lists or other elements seem to have stopped working after a recent hugo upgrade. So now I see literal {.some-class} in the output. I believe goldmark supported these but only for headings and blackfriday doesn't seem to support them at all. The docs still mention block-level attributes, but they no-longer seem to be working 😢.

@mohkale sources still point to mmark v1.

@oblitum

That's strange. Must be a configuration update or something to that affect. I've downgraded to v0.85.0 and everything seems to be working again.

[oblitum]

Oh no. Mmark is set to be removed on 0.88!

This is still just as relevant today as it was before. Anyway, I personally don't care anymore, I've pinned the last version of hugo that supported Mmark (which has been dropped already in the latest versions) on all installations I have because I'm not willing to convert all my Mmark content to another thing just to miss features. Feel free to close.
