========================
LMS and Learner Features
========================

* We’ve enhanced the learner profiles so that they now include the date a
  learner joined the platform and any course credentials they have received.
  Learner profiles link to social media accounts and help learners share 
  information with one another. 
* Learners now have the ability to purchase all the courses in a
  program in just one transaction. This avoids the hassle of having to enter
  payment information multiple times.
* New discussion notifications now send an email message the first time a 
  learner's post receives a comment. The message contains the comment and a 
  link back to the course discussions for easy access. Inline discussions are 
  expanded by default. This change has led to a threefold increase in 
  discussion participation on edx.org.​


===============================
Studio and Course Author Tools
===============================

* Course teams now have the ability to override learner scores for individual 
  problems. This can be done through a setting on both the instructor dashboard 
  and the Staff Debug viewer.
* Course Reviews can now be viewed and added by learners from within the course 
  experience. Open edX system administrators can configure a reviews provider, 
  such as CourseTalk, to allows learners to leave reviews for a particular course.
* Proctored exams have been improved, enabling course teams to add specific exam 
  instructions in the Studio proctored exam settings.
* The Files & Uploads page has been updated to significantly simplify the 
  experience of adding all types of files to a course. This includes the 
  ability to search and a Hide File Preview option.
* The ORA problem editor has been improved. A new interface offers the same 
  formatting options for the prompt that are available for HTML components. 
  You no longer have to create a separate HTML component above the ORA 
  assignment.
* Weekly course highlight messages can now be sent to encourage learners to 
  remain engaged with self-paced courses. Specify a few highlights for each 
  course section, and the platform sends out a weekly email message that lists 
  these highlights. Courses on edx.org that enabled weekly highlights had 
  higher verification rates than ones without.
* The HTML components have been updated to give you even more easy formatting 
  options such as aligning your text the way you want: aligned to the left or 
  right, centered, or fully justified. Images in HTML components can be added 
  right inside the HTML component itself, without having to upload files 
  beforehand.
* The Video Uploads page is enabled by default. For course teams who partner 
  with 3Play Media and cielo24, transcripts (including translations of 
  transcripts) are added to Studio automatically.
* You can establish a password policy to require a minimum strength and 
  complexity for passwords.

Changes to OLX <transcript> Element for Videos 
**********************************************

The primary storage for video transcripts on edx.org is now Amazon S3. In
connection with this change, we have made changes to the ``<transcript>``
element for videos in OLX, which is the XML-based standard for course export
and import on edX. The ``<transcript>`` element, which was formerly a child of
the ``<video>`` element, is now a child of a ``<transcripts>`` element, which
is in turn a child of the ``<video_asset>`` element. Here is an example of an
OLX ``<video>`` element, showing the way transcripts are now handled.

.. code-block:: xml

    <video sub="" display_name="Test Video" edx_video_id="9c563e7d-c86c" 
           youtube_id_1_0="FEWSxCV">
        <video_asset client_video_id="test.mp4" duration="319.94" image="">
            <encoded_video bitrate="174" file_size="69880" profile="mobile_low" 
                           url="https://abc.cloudfront.net/ABC_MB2.mp4"/>
            <encoded_video bitrate="192" file_size="76816" profile="audio_mp3"
                           url="https://def.cloudfront.net/ABC_MB1.mp3"/>
            <encoded_video bitrate="279" file_size="112012" profile="desktop_mp4" 
                           url="https://ghi.cloudfront.net/ABC_MB4.mp4"/>
            <encoded_video bitrate="0" file_size="0" profile="youtube" url="FEWSxCV"/>
            <transcripts>
                 <transcript file_format="srt" language_code="en" provider="Custom"/>
                 <transcript file_format="srt" language_code="de" provider="Custom"/>
           </transcripts>
        </video_asset>
    </video>

Transcript content files are stored in the course's ``/static`` directory, 
using the file name format ``[edx_video_id]-[language_code].srt``. For example, in 
the preceding example, there should be a transcript file with the name 
``9c563e7d-c86c-en.srt`` in the ``/static`` directory.

***********************
Deprecated Features
***********************

Several features are deprecated or deleted in the Open edX Hawthorn release.

* The waffle flag ``unified_course_view``, which can be used for the new view
  of the course outline on a separate page, was deprecated in Ginkgo.  The old
  sidebar navigation and this waffle flag will be fully removed in the next
  release. We recommend switching this flag to ``True``, so that you will not
  experience any change with the next release.
* ``django-simple-history`` has been deprecated and removed.
* The ``LogoutViewConfiguration`` model has been removed. Single logout is now 
  permanently enabled. This meants that logging out of the LMS or an IDA logs 
  you out of all systems.
