| See https://github.com/mathjax/MathJax/releases/tag/4.0.0 There are plenty of new stuff in the release notes. To be checked to see what we could use. Note that as of today, the latest version on webjars.org is 4.0.0-alpha.1 so we either need to wait for someone to package the 4.0.0 version or provide it ourselves. |
