As pointed out on Mathematics Meta, Stack Exchange still uses MathJax v2, although v4 was released recently. (The answer by Davide Cervone - one of the MathJax developers - summarized some potential problems when moving from v2 to v3 or v4.)
- Are there plans to switch to a newer version of MathJax on Stack Exchange sites which use MathJax?
- If yes, is there some kind of estimate when this could happen?
I am asking partly because some of the MathJax-related bugs which are reported on various per-site-metas would probably be resolved by this switch. For example, recently I saw this post where the answer was that this would not be a problem with MathJax v3 or v4: Double overline renders poorly, except in MathML.
If there are plans to switch to a newer version soon, it would probably make sense to wait with reporting (or resolving) various MathJax-related bugs after that date.
