The following information summarizes what is new in the edX platform this week.

The edX engineering wiki Release Pages provide detailed information about every change made to the edx-platform GitHub repository. If you are interested in additional information about every change in a release, create a user account for the wiki and review the dated release pages.

## EdX LMS¶

The cohort management section of the instructor dashboard now displays status information to help course teams determine whether the feature is enabled and working correctly. (TNL-4393)

## Open EdX¶

On 5 May 2016, a change to the courseware_studentmodulehistory database table was released to the edx-platform repository. This change requires a new database configuration and offers an optional data migration. The change affects all Open edX installations that follow master. If you are responsible for maintaining an Open edX instance, including a devstack, fullstack, or production installation, you must prepare for this change before you upgrade to the 5 May 2016 version of master.

Note

No changes are required or supported at this time for Open edX installations that use the Dogwood release.
