MathJax is the modern JavaScript-based LaTeX rendering solution for the Internet. The module ships with library configurations that do not escape JavaScript within the TeX it formats. *Notice:* This release updates CDN URLs where possible and adds a system status warning for unsafe configurations. If you are unable to upgrade immediately, you can modify either the CDN URL or the custom MathJax JavaScript configuration according to the instructions in MathJax Safe-mode [3]. Solution: Install the latest version: * If you use the MathJax module, upgrade to MathJax 4.1.2 [4] * Check the Drupal status report for MathJax module warnings. If "safe mode is not enabled" appears, the MathJax configuration couldn't be automatically updated. Read the information above to manually fix the configuration.
