What's New in MathJax v2.6

MathJax v2.6 includes a number of new features, as well a more than 30 important bug fixes. The following are some of the highlights.

Features

  • Improved CommonHTML output. The CommonHTML output now provides the same layout quality and MathML support as the HTML-CSS and SVG output. It is on average 40% faster than the other outputs and the markup it produces are identical on all browsers and thus can also be pre-generated on the server via MathJax-node. The fast preview mechanism introduced in v2.5 continues to develop as a separate output as PreviewHTML <configure-PreviewHTML> and the fast-preview <configure-fast-preview> extension.
  • Accessibility improvements. We thank the AT community for their guidance, support, and feedback in our efforts towards making MathJax completely accessible to all users.
    • Screenreader compatibility. The new AssistiveMML extension enables compatibility with most MathML-capable screenreaders by inserting visually-hidden MathML alongside MathJax's visual output. See screenreader support <screenreader-support> for details on the expected behavior as well as background on the limitations due to lack of web standards and browser/OS technology.
    • Accesssible UI. We have improved the accessibility of the MathJax menu to enable assistive technology users to easily access its features, cf. MathJax UI <mathjax-ui-a11y>.
  • PlainSource Output. The new PlainSource output will revert the rendering back to the input format; in the case of MathML, the output will prefer TeX and AsciiMath from <annotation-xml> elements. This helps with accessibility and copy&paste of document fragments.
  • Semi-slim MathJax repository for bower. You can now use bower install components/MathJax to install a fork of MathJax without PNG fonts. Many thanks to @minrk from the IPython/Jupyter team and to the team at components!
  • MathJax via npm. You can now use npm install mathjax to install a copy of MathJax without PNG fonts.
  • Deprecated: MMLorHTML extension. We have deprecated the MMLorHTML extension. For a detailed guide on configuring MathJax to choose different outputs on different browsers, please see Automatic Selection of the Output Processor <automatic-output-switch> for more information.

Numerous bugs and issues have also been resolved; for a detailed listing please check the release milestone.
