After a successful beta run, we’re happy to officially release MathJax v2.2.
MathJax v2.2 is available on the CDN, and for download from GitHub or via the download page at http://www.mathjax.org/
Version 2.2 is available on the CDN at
and starting today the files at the
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.
