Studio/LMS: Added ability to set due date formatting through Studio's Advanced
Settings.  The key is due_date_display_format, and the value should be a format
supported by Python's strftime function.
527

528 529 530
Common: Added configurable backends for tracking events. Tracking events using
the python logging module is the default backend. Support for MongoDB and a

533 534
can be included to courses.

Studio: Allow course authors to set their course image on the schedule
and details page, with support for JPEG and PNG images.

541 542 543
LMS, Studio: Centralized startup code to manage.py and wsgi.py files.
Made studio runnable using wsgi.

544 545
Blades: Took videoalpha out of alpha, replacing the old video player

546 547 548 549
Common: Allow instructors to input complicated expressions as answers to
`NumericalResponse`s. Prior to the change only numbers were allowed, now any
answer from '1/3' to 'sqrt(12)*(1-1/3^2+1/5/3^2)' are valid.

550 551 552 553 554
Studio/LMS: Allow for 'preview' and 'published' in a single LMS instance. Use
middlware components to retain the incoming Django request and put in thread
local storage. It is recommended that all developers define a 'preview.localhost'
which maps to the same IP address as localhost in his/her HOSTS file.

555 556 557 558
LMS: Enable beta instructor dashboard. The beta dashboard is a rearchitecture
of the existing instructor dashboard and is available by clicking a link at
the top right of the existing dashboard.

559 560 561 562 563 564 565 566 567
Common: CourseEnrollment has new fields `is_active` and `mode`. The mode will be
used to differentiate different kinds of enrollments (currently, all enrollments
are honor certificate enrollments). The `is_active` flag will be used to
deactivate enrollments without deleting them, so that we know what course you
*were* enrolled in. Because of the latter change, enrollment and unenrollment
logic has been consolidated into the model -- you should use new class methods
to `enroll()`, `unenroll()`, and to check `is_enrolled()`, instead of creating
CourseEnrollment objects or querying them directly.

568 569 570
LMS: Added bulk email for course feature, with option to optout of individual
course emails.

571 572 573
Studio: Email will be sent to admin address when a user requests course creator
privileges for Studio (edge only).

574 575 576
Studio: Studio course authors (both instructors and staff) will be auto-enrolled
for their courses so that "View Live" works.

577 578 579 580
Common: Add a new input type ``<formulaequationinput />`` for Formula/Numerical
Responses. It periodically makes AJAX calls to preview and validate the
student's input.

status has changed. This will not be in use until the course creator table
is enabled.

589 590 591
Studio: Added improvements to Course Creation: richer error messaging, tip
text, and fourth field for course run.

592 593 594 595 596 597 598 599 600 601
Blades: New features for VideoAlpha player:
1.) Controls are auto hidden after a delay of mouse inactivity - the full video
becomes visible.
2.) When captions (CC) button is pressed, captions stick (not auto hidden after
a delay of mouse inactivity). The video player size does not change - the video
is down-sized and placed in the middle of the black area.
3.) All source code of Video Alpha 2 is written in JavaScript. It is not a basic
conversion from CoffeeScript. The structure of the player has been changed.
4.) A lot of additional unit tests.

602 603 604 605 606
LMS: Added user preferences (arbitrary user/key/value tuples, for which
which user/key is unique) and a REST API for reading users and
preferences. Access to the REST API is restricted by use of the
X-Edx-Api-Key HTTP header (which must match settings.EDX_API_KEY; if
the setting is not present, the API is disabled).
607

608 609 610
LMS: Added endpoints for AJAX requests to enable/disable notifications
(which are not yet implemented) and a one-click unsubscribe page.

611 612 613

this allows instructors to hand off management of a course to someone else.

  only use templates as override samples.
671
- create new instances via in memory create_xmodule and related methods rather

672 673 674
  than cloning a db record.
- have an explicit method for making a draft copy as distinct from making a
  new module.

the associated javascript)

687 688 689
Studio: For courses running on edx.org (marketing site), disable fields in
Course Settings that do not apply.

690 691 692

watcher is already running in another shell).

Common: Developers can now have private Django settings files.

Common: Safety code added to prevent anything above the vertical level in the
course tree from being marked as version='draft'. It will raise an exception if
the code tries to so mark a node. We need the backtraces to figure out where
this very infrequent intermittent marking was occurring. It was making courses
look different in Studio than in LMS.

Stanford.
