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.
