MathJax version 2.0 now available

[Davide P. Cervone]

MathJax v2.0 is now available on the CDN, and for download from GitHub or the download page at

http://www.mathjax.org/download/

Version 2.0 is available on the CDN at

http://cdn.mathjax.org/mathjax/2.0-latest/MathJax.js

and the files at the

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

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 (I am not sure exactly how long that takes).  

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://www.mathjax.org/docs/2.0/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.

Well, it looks like the files in mathjax/latest tree on Cloudfront aren't expiring as quickly as I hoped, and people are getting a mixture of the two versions, which causes math processing errors (since the two versions aren't interchangeable).  The files were supposed expire after an hour, but it looks like the expiration dates didn't propagate, and so they still have the 1 day expirations.  That means it may take until tomorrow for this to clear.  I'm working on trying to force the expiration to occur, but haven't accomplished that.

If you can, you should switch to 

http://cdn.mathjax.org/mathjax/2.0-latest/MathJax.js

if you are currently using mathjax/latest/MathJax.js, as that will work properly.

I regret the trouble this is causing you and your users.  We are working on the problem and hope to have it cleared up soon.  Your patience is appreciated.

The MathJax CDN distribution at mathjax/latest should (finally) be working properly again, serving MathJax version 2.0.  I apologize for the disruption in service, and regret the inconvenience it caused you and your users.  Our upgrade procedures are being modified so that the problem will not occur again in the future.  

If you changed from mathjax/latest to mathjax/2.0-latest it should be safe to switch back again.  At this point, clearing the browser cache and reloading the page should restore functionality for anyone who is still experiencing problems.

Please let us know if there are any additional issues.  Again, my apologies.  Your patience was very much appreciated.

I just tried the different rendering mode and saw a typo here:

"Your browser's native MathML does not implement all the features used
by MathJax, so some expressions *my* render improperly."

[Davide P. Cervone]

Yes, it's been reported, and will be fixed in the next release. If
you want to fix it in your own configuration, I can tell you how.

OOPS, sorry, I responded to you thinking I was responding to the other
user who reported it. Sorry!

I meant to say "thanks for reporting it. I'll take care of it."
