# Extension:Math/Announcement

To be posted after deployment on October 23. See http://lists.w3.org/Archives/Public/www-math/2014Oct/0003.html for the announcement on the MathML mailing list. This is a user centric announcement of the new features.

## Introducing Math rendering 2.0

Dear Wikipedians,

We'd like to announce a major update of the Math (rendering) extension.

For registered Wikipedia users, we have introduced a new math rendering mode using MathML, a markup language for mathematical formulae. Since MathML is not supported in all browsers [1], we have also added a fall-back mode using scalable vector graphics (SVG).

Both modes offer crisp rendering at any resolution, which is a major advantage over the current image-based default. We'll also be able to make our math more accessible by improving screenreader and magnification support.

We encourage you to enable the MathML mode in your Appearance preferences. As an example, the URL for this section on the English Wikipedia is: https://en.wikipedia.org/wiki/Special:Preferences#mw-prefsection-rendering

For editors, there are also two new optional features:

1) You can set the "id" attribute to create math tags that can be referenced. For example, the following math tag

${\displaystyle E=mc^{2}}$

can be referenced by the wikitext

This is true regardless of the rendering mode used.

2) In addition, there is the attribute "display" with the possible values "block" or "inline". This attribute can be used to control the layout of the math tag with regard to centering and size of the operators. See https://www.mediawiki.org/wiki/Extension:Math/Displaystyle for a full description, of this feature.

Your feedback is very welcome. Please report bugs in Bugzilla against the Math extension, or post on the talk page here: https://www.mediawiki.org/wiki/Extension_talk:Math

All this is brought to you by Moritz Schubotz and Frédéric Wang (both volunteers) in collaboration with Gabriel Wicke, C. Scott Ananian, Alexandros Kosiaris and Roan Kattouw from the Wikimedia Foundation. We also owe a big thanks to Peter Krautzberger and Davide P. Cervone of MathJax for the server-side math rendering backend.

Best Gabriel Wicke (GWicke) and Moritz Schubotz (Physikerwelt)
