MathJax v2.0 is now available on the CDN, and for download from GitHub or the download page at docs.mathjax.org.
Version 2.0 is available on the CDN at
and the files at the
address have been switched over the v2.0 as well, but it will 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 servers, there may be a mixture of files in your users’ caches, and so they may need to clear their cache and restart their browser in order to get a consistent version of the files. If this turns out to be problematic for you, you can change (temporarily) to the mathjax/2.0-latest URL instead of mathjax/latest since that is a new address that will not have any cached older versions to worry about. Change back after a day or two when the new version has migrated to all the locations in the cloud.
See http://docs.mathjax.org/en/v2.0-latest/whats-new-2.0.html for details about the changes in v2.0, and some caveats about the effect of these changes on existing sites.
We anticipate a smooth upgrade from v1.1 to v2.0, but as always, let us know if you experience problems with this new version of MathJax. Thank you for your continued support.
