We browsed the Open edX documentation and collected  the list of all Eucalyptus improvements for learners and course authors. They are listed below, with short explanations on each fix or update.

LMS updates

• Dashboard with Analytics. More detailed and up-to-date information about enrollment is available on the course dashboard.
• Reporting on a Problem. Increased learner support through prevention of a user from manually entering a course name when submitting a problem and, thus, reducing the time to resolve the learner's concern. 
• Accessibility Improvements. Better experience for screen reader users and for learners relying on keyboards is now provided.
• Discussions Sorting by most votes, most activity, and recent activity.
• Correct answer is indicated by a check mark as well (if Show Answer setting is active for a problem). 
• Commenting with screen readers improvement. In discussion forum, users with screen readers now get pointed to a correct part of the discussion after they post a comment.
• Standard radio buttons. Standard radio buttons describing post type are now used during new post creation to help users with high contrast schemes identify the post type easier. 
• No tools announcement. If “no tools” option is enabled, course learner notes and calculator tools are not announced to screen readers.

• Searchable Insights Course Pages. Course authors and staff now can search the courses on Insights Course pages by course ID or name.
