``` did historically do highlighting. It produced the automatic code detection we discussed here:
and you polled about removing here:
My experience was that highlighting was applied to essentially everything, even when the content of the block was surely insufficient for a detection.
Even though I do not like the way the auto detect causes inappropriate highlighting in non-code content, I did not notice a significant incidence of incorrect detection of C++/Arduino Language code up until the report last week, which was a very glaring failure.
This is what made me think there was some change to the forum software. On the other hand, I always use an identifier in every code block (including text when I don't want any highlighting at all), so I am much less likely to encounter incorrect language detections.
