This new release corrects the math rendering issue, but did not solve all of the IE9 problems. We will continue to work toward improving our performance in IE9. More information is on our Browser Support page.
The release also contains 2 other additions.
- A Google +1 button is now displayed on all content next to the Facebook and Twitter buttons. Users can show their appreciation for a module or collection by giving it a +1 or by sharing it on Google+. Giving a module or collection a +1 can improve its ranking in Google search results.
- We added a link to our new Google+ page in the footer of most non-content pages.
