MathJax v2.7.2 beta now available

Today we are entering the public beta phase of MathJax v2.7.2, a bug-fix release with over 30 important bug fixes.

This release includes a workaround for a regression in Safari when using combining characters as well as an important update to the MathJax Accessibility Extensions and the underlying speech-rule-engine, greatly improving performance and quality.

For details on all bug fixes, please see below.

The beta should be available on all CDN providers, e..g., cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.2-beta.1/MathJax.js which you can load it in place of the version you are currently using. Alternatively, you can get a ZIP archive or access the branch on GitHub.


Remember that this is still beta software, so if you are not an experienced user, you may want to wait for the official 2.7.2 release. We do not recommend that you use the -beta version for production environments, but do encourage you to test your content with it.

The official release of v2.7.2 should occur within the next few weeks, but we want you to be able to start to test out the v2.7.2 features now. Please report any bugs you find to the issue tracker at https://github.com/mathjax/MathJax/issues.

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

The MathJax Team.
