# Week of 11 July 2016¶

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.

## Studio¶

To ensure that every text input problem includes a correct answer value, an edit check has been added to the advanced editor. These problems are now checked for an answer attribute value.

Previously, course team members could leave the answer attribute empty (<stringresponse answer=" " type="ci" >), which resulted in a question that learners could not answer correctly. (TNL-4141)

## LMS¶

• To anticipate and answer learners’ questions about certificate availability, the Progress page now includes the following message for learners who are enrolled in the audit track.

“You are enrolled in the audit track for this course. The audit track does not include a certificate.”

• An error in the way that responses to questions were presented in the course discussions has been corrected. The error caused responses to retain the “marked as answer {time frame} by {username}” message even after a discussion moderator or the original poster had unmarked them. This message no longer appears for responses that have been unmarked. (TNL-4392)
