What's New in MathJax v2.3
**************************
MathJax v2.3 includes a number of new features, as well a more than 30
important bug fixes.
Features:
=========
* *New webfonts:* MathJax v2.3 adds new webfonts for ``STIX``, ``Asana
Math``, ``Neo Euler``, ``Gyre Pagella``, ``Gyre Termes``, and
``Latin Modern``.
* *Localization improvements:* MathJax has been accepted into
TranslateWiki.net. Thanks to the TWN community we could add
12 complete and over 20 partial translations.
* *MathML improvements:* MathJax’s "Show Math as" menu will now expose
the MathML annotation features. There are also two new preview
options for the MathML input mode: ``mathml`` (now the default),
which uses the original MathML as a preview, and ``altimage``, which
uses the ``<math>`` element's ``altimg`` (if any) for the preview.
* *Miscellaneous improvements:* A new extension ``MatchWebFonts``
improves the interaction with the surrounding content when that uses
a webfont. A new configuration method allows configurations to be
specified using a regular JavaScript variable ``window.MathJax``.
* MathJax is now available as a Bower package thanks to
community contributions.
