Important: how the shutdown of cdn.mathjax.org affects Numbas
The MathJax team has announced that their free cdn.mathjax.org service, which serves copies of MathJax, will shut down on April 30, 2017 – the end of this month. Numbas uses MathJax to render mathematical notation using LaTeX, and until now the default theme has used cdn.mathjax.org.
This is much less notice than we would’ve liked, but it’s out of our hands. So we need to change how Numbas uses MathJax from now on, and the shutdown has ramifications for existing exam packages.
How Numbas will use MathJax from now on
In short: there’s a new default URL, and you shouldn’t notice any difference. You can configure Numbas to use your own copy of MathJax if you’d prefer.
