The following information reflects what is new in the edX Platform as of June 10,
|
|
2014. See previous pages in this document for a history of changes.
|
|
|

****************************************
|
|
edX Release Announcements Mailing List
|
|
****************************************
|
|
|
|
These edX Course Staff Release Notes are always available and are updated with
|
|
each release of the edX Platform on `edx.org`_ and `edX Edge`_.
|
|
|
|
In addition, you can sign up for the new `edX Release Announcements mailing
|
|
list`_ to get an email message when we have updated the edX Course Staff Release
|
|
Notes.
|
|
|
|
|
|
***************************************
|
|
The New Key Introspection API
|
|
***************************************
|
|
|
|
This release implements a change in the edX Platform software architecture. The
|
|
Key Introspection API is now used to uniquely identify Xblocks, the building
|
|
blocks for edX courses. This change simplifies the way that the application
|
|
identifies the course content internally. This change does not affect how you
|
|
author content.
|
|
|
|
In edX Studio, URL formats have changed for all courses. If you previously bookmarked a page in Studio, that bookmark will no longer work. You must update the URL.
|
|
|
|
Following is a sample of this format change:
|
|
|
|
* Old URL: ``https://studio.edx.org/course/OrganizationX.Econ101.2014_T1/branch/draft/block/2014_T1``
|
|
|
|
* New URL: ``https://studio.edx.org/course/slashes:OrganizationX+Econ101+2014_T1``
|
|
|
|
This change does not affect student-visible URLs.
|
|
|
|
In the edX LMS, the only change is that to reset attempts or rescore student
|
|
responses in the **Student Admin** tab on the Instructor Dashboard, you must now
|
|
specify the complete location identifier of the problem. The `Student Grades and
|
|
Grading`_ section is updated with this revised requirement.
|
|
|
|
For additional technical detail about this architectural change and the opportunities it creates, see `Opaque Keys`_ on the GitHub wiki.

|
|
edX Learning Management System
|
|
***************************************
|
|
|
|
* A problem with the **Register** button on `edX Edge`_ is fixed. If you are not
|
|
logged in to edX Edge, you are redirected to the login page, from which new
|
|
users can register.
|
|
|
|
* If a student's browser does not support HTML5 videos, and the course video is
|
|
only available in HTML5, the following error message is now displayed to the
|
|
student: ``This browser cannot play .mp4, .ogg, or .webm files. Try using a
|
|
different browser, such as Google Chrome.`` (BLD-638)
|
|
|
|
* Video transcripts are now displayed correctly on iPads. (BLD-1033)
|
|
|
|
===========================
|
|
Accessibility Improvements
|
|
===========================
|
|
|
|
* Drag and drop problems are updated to improve accessibility for screen
|
|
readers:
|
|
|
|
* User interface elements that receive focus now have a visual focus
|
|
indicated. (LMS-1940)
|
|
|
|
* Each user interface element now exposes its name, state, role, and value to
|
|
assistive technologies. (LMS-1904)
|
|
|
|
* The target image now has an ``alt`` attribute. (LMS-1699)
