What's New in MathJax v2.5

MathJax v2.5 includes a number of new features, as well a more than 70 important bug fixes. The following are some of the highlights.

Features

  • Speed improvements. The HTML-CSS output performance was improved by 30-40% (depending on content complexity, with higher gains in more complex content such as very long documents).
  • New output for fast preview. The new CommonHTML output provides a rough but 10x-faster rendering. The CHTML-preview extension will use this fast output as a preview mode for HTML-CSS or SVG output.
  • Improved Content MathML support. Content MathML is now fully supported via a new extension, in particular this allows customization of the conversion process.
  • Improved elementary math support The experimental support for elementary math elements has been significantly improved special thanks to David Carlisle.
  • NodeJS compatibility. Enable the implementation of a NodeJS API (released as MathJax-node <https://github.com/mathjax/MathJax-node>__).

Numerous display bugs, line-breaking problems, and interface issues have been resolved; for a detailed listing please check the release milestone <https://github.com/mathjax/MathJax/issues?milestone=4&state=closed>__.
