MathJax v2.7.3 now available

We are happy to officially release MathJax v2.7.3 today.

This is mostly a bug-fix release, with a few enhancements as well.

The primary enhancement is the addition of version 2.3 of the Speech-Rule Engine that underlies the MathJax accessibility tools. This includes performance enhancements as well as a Spanish localization that is tied to the MathJax localization menu. In addition, the Explorer menu in the Assistive submenu has been slimmed down to remove unneeded options.

For details on all bug fixes and enhancements, please see below.

This release should be available on all CDN providers, e.g., https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.3/MathJax.js which you can load it in place of the version you are currently using (or load latest.js instead of Mathjax.js to get the latest version 2.x, whatever it is, but note that this loads asynchronously, so the MathJax global variable may not be available immediately).

Alternatively, you can get a ZIP archive or access the branch on GitHub.

Thanks for your continuing interest in MathJax. We hope that this release makes your MathJax experience even better.

The MathJax Team.
