@ -13,3 +13,10 @@ library and install it locally, then use this filter to load that local version.
The only changes required to this filter to handle different MathJax versions is to update
the default CDN urls in settings.php - and update the list of language mappings - in filter.php.
This filter does however include the MathJax Accessibility extensions from
https://github.com/mathjax/MathJax-a11y
To update the extensions download the latest release from https://github.com/mathjax/MathJax-a11y/releases
. Delete all the files from "contrib/ally" and extract the files from the zip to the same folder. Then
update the version numbers in the lib/thirdpartylibs.xml.
