These are notable changes in edx-platform. This is a rolling list of changes, in roughly chronological order, most recent first. Add your entries at or near the top. Include a label indicating the component affected.
LMS: Change bulk email implementation to use less memory, and to better handle duplicate tasks in celery.
LMS: Improve forum error handling so that errors in the logs are clearer and HTTP status codes from the comments service indicating client error are correctly passed through to the client.

Studio: added restful interface for finding orphans in courses. An orphan is an xblock to which no children relation points and whose type is not in the set contentstore.views.item.DETACHED_CATEGORIES nor 'course'.
- GET http://host/orphan/org.course returns json array of ids.
- Requires course author access.
- DELETE http://orphan/org.course deletes all the orphans in that course.
- Requires is_staff access
Studio: Bug fix for text loss in Course Updates when the text exists before the first tag.
Blades: Hovering over CC button in video player, when transcripts are hidden, will cause them to show up. Moving the mouse from the CC button will auto hide them. You can hover over the CC button and then move the mouse to the transcripts which will allow you to select some video position in 1 click.
Blades: Add possibility to use multiple LTI tools per page.
Blades: LTI module can now load external content in a new window.

Studio: Switched to loading Javascript using require.js
Studio: Better feedback during the course import process

CMS: Add edit_course_tabs management command, providing a primitive editing capability for a course's list of tabs.
Studio and LMS: add ability to lock assets (cannot be viewed unless registered for class).
Studio: add restful interface for paging assets (no UX yet, but just add /start/45/max/50 to end of url to get items 45-95, e.g.)
LMS: First round of improvements to New (beta) Instructor Dash: improvements, fixes, and internationalization to the Student Info section.
LMS: Improved accessibility of parts of forum navigation sidebar.
LMS: enhanced accessibility labeling and aria support for the discussion forum new post dropdown as well as response and comment area labeling.
Blades: Add Studio timed transcripts editor to video player.

LMS: Experimental feature using the ICE change tracker JS pkg to allow peer assessors to edit the original submitter's work.
LMS: Fixed a bug that caused links from forum user profile pages to threads to lead to 404s if the course id contained a '-' character.
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.
Common: Added configurable backends for tracking events. Tracking events using the python logging module is the default backend. Support for MongoDB and a Django database is also available.
Blades: Added Learning Tools Interoperability (LTI) blade. Now LTI components can be included to courses.
LMS: Added alphabetical sorting of forum categories and subcategories. It is hidden behind a false defaulted course level flag.

LMS, Studio: Centralized startup code to manage.py and wsgi.py files. Made studio runnable using wsgi.
Blades: Took videoalpha out of alpha, replacing the old video player
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.
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.
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.
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.
LMS: Added bulk email for course feature, with option to optout of individual course emails.
Studio: Email will be sent to admin address when a user requests course creator privileges for Studio (edge only).
Studio: Studio course authors (both instructors and staff) will be auto-enrolled for their courses so that "View Live" works.

Responses. It periodically makes AJAX calls to preview and validate the
student's input.

Studio: Added improvements to Course Creation: richer error messaging, tip text, and fourth field for course run.
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.
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).
LMS: Added endpoints for AJAX requests to enable/disable notifications (which are not yet implemented) and a one-click unsubscribe page.
Studio: Allow instructors of a course to designate other staff as instructors; this allows instructors to hand off management of a course to someone else.
Common: Add a manage.py that knows about edx-platform specific settings and projects

LMS: Problem rescoring. Added options on the Grades tab of the Instructor Dashboard to allow a particular student's submission for a particular problem to be rescored. Provides an option to see a history of background tasks for a given problem and student.
Blades: Small UX fix on capa multiple-choice problems. Make labels only as wide as the text to reduce accidental choice selections.
Studio: - use xblock field defaults to initialize all new instances' fields and
only use templates as override samples.
- create new instances via in memory create_xmodule and related methods rather than cloning a db record.
- have an explicit method for making a draft copy as distinct from making a new module.
Studio: Remove XML from the video component editor. All settings are moved to be edited as metadata.
XModule: Only write out assets files if the contents have changed.
Studio: Course settings are now saved explicitly.

LMS: Fixed the preferences scope for storing data in xmodules.
LMS: Forums. Added handling for case where discussion module can get None as value of lms.start in lms/djangoapps/django_comment_client/utils.py
Studio, LMS: Make ModelTypes more strict about their expected content (for instance, Boolean, Integer, String), but also allow them to hold either the typed value, or a String that can be converted to their typed value. For example, an Integer can contain 3 or '3'. This changed an update to the xblock library.
LMS: Courses whose id matches a regex in the COURSES_WITH_UNSAFE_CODE Django setting now run entirely outside the Python sandbox.
Blades: Added tests for Video Alpha player.
Common: Have the capa module handle unicode better (especially errors)
Blades: Video Alpha bug fix for speed changing to 1.0 in Firefox.
Blades: Additional event tracking added to Video Alpha: fullscreen switch, show/hide captions.

Common: all dates and times are not time zone aware datetimes. No code should create or use struct_times nor naive datetimes.
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.
Deploy: MKTG_URLS is now read from env.json.
Common: Theming makes it possible to change the look of the site, from Stanford.
