APS is involved in several activities to advance and diffuse the knowledge of physics including a strong publication program with landmark titles such as Physical Review Letters, the Physical Review journals, and Reviews of Modern Physics. APS has been an early proponent of new technologies and standards for electronic publication of mathematical content, and one of the first major scholarly publishers to embrace the MathML standards for mathematics.

“APS will be launching fully text HTML versions of our articles later this year for the first time. MathJax is the key technology that is enabling us to finally do this in a superior manner that we expect will meet the high expectations of our journal readers. We continue to be excited about the rapid development of MathJax and our ongoing collaboration with the team.” comments Mark Doyle, Director, Journal Information Systems, APS.

We look forward to continuing the collaboration with APS, and welcome their ongoing support for the MathJax project.

MathJax v2.2 is available on the CDN, and for download from GitHub or via the download page at http://www.mathjax.org/download/.

Version 2.2 is available on the CDN at

http://cdn.mathjax.org/mathjax/2.2-latest/MathJax.js

and starting today the files at the

http://cdn.mathjax.org/mathjax/latest/MathJax.js

address will be switched over the v2.2; it may take some time for them to propagate out to the distributed cloud servers.

During the time that the files are making their way out to the CDN’s servers, there may be a mixture of files in a browser cache, and so users may need to clear their cache and restart their browser in order to get a consistent version of the files.

If you are a page author and concerned about this, you can change (temporarily) to the mathjax/2.2-latest URL instead of mathjax/latest since that is a new address that will not have any cached older versions to worry about. You can switch back to mathjax/latest after a day or two when the new version has migrated to all the locations in the cloud.

See http://docs.mathjax.org/en/latest/whats-new-2.2.html for details about the changes in v2.2, and some caveats about the effect of these changes on existing sites.

We anticipate a smooth upgrade from v2.1 to v2.2, but as always, let us know on the bug tracker if you experience problems with this new version of MathJax.  Thank you for your continued support.

The MathJax Team.

“Elsevier’s long term support has been invaluable to the MathJax project, past, present and future. Elsevier becoming a MathJax Partner is a great vote of confidence and we look forward to continuing our collaboration. The rich feedback and support we receive from our sponsors enables us to keep our bearing as we create a web where math and science are as much home as they are throughout education and research.”, said Peter Krautzberger, MathJax manager.

“The relationship we have formed with MathJax is a natural fit to our commitment to support initiatives that benefit authors, researchers and the mathematics community,” says Laura Hassink, Senior Vice President Physical Sciences at Elsevier. “We are delighted to expand our cooperation with MathJax.”

We look forward to continuing the collaboration with Elsevier, and welcome their ongoing support for the MathJax project.

git clone git://github.com/mathjax/MathJax.git MathJax-2.2
cd MathJax-2.2
git checkout v2.2-beta

at an appropriate location on your server.

Remember that this is still beta software, so if you are not an experienced user, you may want to wait for the official 2.2 release. We do not recommend that you use the 2.2-beta version for production environments, but do encourage you to test your sites with it.

If you’re linking to http://cdn.mathjax.org/mathjax/latest/MathJax.js, note that at the point of the official release of v2.2, the address will begin to serve MathJax v2.2. You can also continue to use v2.1 by linking to http://cdn.mathjax.org/mathjax/2.1-latest/MathJax.js instead — and you can change to that version at any point (it is available now). Once the official v2.2 release is made, the v2.2-beta address will be removed from the CDN.

The official release of v2.2 should occur within the next two weeks, but we wanted you to be able to start to test out the v2.2 features now. Please report any bugs you find to the issue tracker at https://github.com/mathjax/MathJax/issues.

Thanks for your continuing interest in MathJax. We hope that this release makes your MathJax experience even smoother.

The MathJax Team.

New in MathJax v2.2

This release improves overall stability by fixing over 40 bugs. For a complete list of bugs that were fixed, please check our issue tracker.

Localization.

MathJax now offers a full localization module. Page authors can specify a locale when loading MathJax.js, e.g., to set French use

<script type="text/javascript"
    src="http://cdn.mathjax.org/mathjax/2.2-beta/MathJax.js?config=TeX-AMS-MML_HTMLorMML&locale=fr">
</script>

Your readers can switch the language manually via the new Language item in the MathJax contextual menu.

The beta release includes English (default), French and German locales and we hope our community will help us to add more languages during the beta phase. We will post more information on the translation process and the configuration options in an upcoming post.

Safe-mode extension.

MathJax provides a powerful HTML-extension. However, on sites with user-generated content, commands like \href and \css can have negative side effects. For example, \href can specify any url protocol, including javascript, while \css can be used to modify any CSS, including a site’s user interface. The new safe extension gives page authors an easy way to restrict such commands.

To load the extension, simply add it when loading MathJax.js, e.g.,

<script type="text/javascript"
    src="http://cdn.mathjax.org/mathjax/2.2-beta/MathJax.js?config=TeX-AMS-MML_HTMLorMML,Safe.js">
</script>

For the configuration, you can set the options in your configuration block. The basic configuration consists of the following block:

MathJax.Hub.Config({
    Safe: {
        allow: {
            URLs: "safe",     
            classes: "safe", 
            cssIDs: "safe",  
            styles: "safe",   
            fontsize: "all",   
            require: "safe"
        }
    },
});

Values can be “all”, “safe”, or “none”, where “all” enables the standard MathJax behavior, “safe” imposes solid restrictions while leaving basic functionality intact and “none” blocks the feature completely.

For full details on all configuration options, check the source.

Commutative diagrams via the AMScd extension.

The well known LaTeX package for commutative diagrams is now available. To load the extension, you need to add it to the TeX block as, e.g.,

TeX: {
  extensions: ["AMScd.js", ...]
}

For how to write commutative diagrams, please refer to the original documentation for now.

Experimental ContentMathML extension.

This experimental extension adds ContentMathML support to MathJax. To load the extension, you have to add it to the MathML block of your configuration, e.g.,

MathML: {
  extensions: ["content-mathml.js", ...]
}

For documentation on ContenMathML, please see the MathML specification.

With 425,000 members in over 160 countries, IEEE fosters technological innovation and excellence for the benefit of humanity. IEEE publishes nearly a third of the world’s technical literature in electrical engineering, computer science and electronics, including more than 160 transactions, journals and magazines. Through its IEEEXplore® digital library, IEEE provides subscribers over three million technical documents including research articles, standards, and conference publications.

“IEEE’s support of MathJax, both financially and as an industry leader, is a huge boost to the project,” said Peter Krautzberger,  MathJax Manager. “MathJax has already greatly benefited from suggestions from IEEE technical staff that have had the opportunity to interact with the tool, and we welcome their ongoing support. Together we can ensure that mathematical content continues its path towards becoming a first class citizen on the web.”

“IEEE is excited to strengthen our commitment to the MathJax effort. This joint collaboration will help increase awareness for MathJax and help us ensure that the quality of published mathematical, technical and scientific content continues to improve”, said Gerry Grenier, IEEE Senior Director of Publishing Technologies.

With the inclusion of MathJax, ScienceDirect can now display high-resolution, fully scalable symbols and equations seamlessly with the surrounding text, improving the readability and interpretation of authors’ research. With this development readers have the ability to magnify equations within an article for closer look, as well as copy and save equations for further research.

“Displaying mathematics and science online is challenging because of limited and inconsistent browser support for web standards such as MathML,” said Peter Krautzberger, MathJax Manager. “MathJax leverages existing web technology such as cascading style sheets and web fonts to provide reliable, clear and accessible rendering. The integration of MathJax within ScienceDirect is a big boost for mathematical and scientific content as it is now displayed natively and accessibly in all articles published in Elsevier journals.”

There are no further requirements for authors, editors and reviewers to benefit from MathJax. As part of the typesetting process, Elsevier converts mathematical symbols and equations included in submitted manuscripts into MathML, the World Wide Web Consortium standard for mathematics on the web. MathJax has the capability of displaying the generated MathML, ensuring that past and future articles published online on ScienceDirect can benefit from the enhanced display.

“Technology enhancements such as MathJax on ScienceDirect support our ongoing efforts to improve the ease-of-use of the research we publish and integrate user-friendly solutions,” says Laura Hassink, Senior Vice President Physical Sciences at Elsevier. “We believe this feature will greatly benefit authors, researchers and the mathematics community as a whole.”

The initiative to develop MathJax as a feature was launched in 2009 by the American Mathematical Society, Design Science, Inc., and the Society for Industrial and Applied Mathematics. Elsevier was one of its first supporters making a commitment to support researchers who want to display and read mathematics on the web. Employing MathJax into research papers published online on ScienceDirect further extends this commitment by enhancing the usability and readability of Elsevier’s content to benefit researchers for the long-term.

Oxford Journals, publishes more than 300 scholarly journals, using MathJax to deliver beautiful, accessible mathematics in journals such as the Monthly Notices of the Royal Astronomical Society and Progress of Theoretical and Experimental Physics, as well as online book products such as Oxford Scholarship Online.

Richard O’Beirne, Digital and Journals Strategy Manager, OUP, said: “We’re delighted to become a MathJax Supporter. MathJax has quietly revolutionized mathematics display in digital products, and integrates seamlessly with author and publishing workflows.”

Becoming a MathJax Supporter helps OUP to make optimal use of MathJax, and makes an important contribution to keeping MathJax the reliable, flexible and open technology it is today.

The MathJax Consortium and its team are grateful for the support provided by its previous managing partner, Design Science, and look forward to continuing the success of the MathJax project.

If you don’t know him by now, Frédéric Wang has been our testing engineer for two years and developed and maintains the MathJax testing framework. Frédéric has been active in the Firefox’s MathML project since 2007 and has worked closely with the W3C Math Working group. He also recently graduated with an M.S. in Mathematics from Pierre and Marie Curie University, Paris.

We’re excited that Frédéric is joining MathJax and we look forward to a productive 2013.
