# Content Update: New editions available for 9 math courses!

We’re excited to share that we recently made significant enhancements to our core math classes! You can learn all the details here.

The newer edition of the course has the same URL as before; we have assigned a different URL to the older edition. If you need to access a specific course edition, just reference the links at the end of this article.

**I assigned (or was assigned) material in the older edition. Will I still be able to access it?**

Yes! Assignments won't be disrupted. The link to your assignments will still take you to the content that was originally assigned in the older edition of the course.

**What happened to the older edition?**

While the older edition is no longer listed in our Courses menu, everything you had access to before is still on the website; just see the “older edition” link for the courses, below. You're always welcome to bookmark either this article or the older course page itself as well.
