Draft of release notes for 2.10.0

Stuart Raeburn
LON-CAPA Technical Director


New Version 2.10.0 Released

Changes from 2.9.1

General User Interface
     - User interface styles, colors and fonts are now more uniform
       throughout LON-CAPA.
     - A consistent style is used for menus and sub-menus.
     - Breadcrumb trails are more ubiquitous.
     - The use of icons is now more common, and in many cases existing
       icons have been replaced with new ones which depict functionality
       more clearly.
     - A compact display is used for common elements on each page.
       In order, from the top:
       - A primary menu which contains links to features which are
         independent of the current role.  This includes a "Messages"
         link which will change to "New Messages" if new LON-CAPA messages
         have been received.
       - A secondary menu containing links to features specific to the
         current role.
       - A breadcrumb trail which encapsulates the context of the
         current page in the hierarchy of menus and sub-menus, and
         in the case of resources in a course also contains icons
         for common utilities (feedback, printout generation etc.).
       - A functions list which contains specific functions for the
         current page available for the current role.
     - Where colors are used to highlight things, colors used are
       subtler and deployed more sparingly within a page.
     - Textareas which support a Rich Text (or WYSIWYG) editor, now
       include a link for each instance to toggle the editor on/off
       for that instance alone.
     - Rich Text Editor updated to CKEditor 3
     - Updated design for "templated" pages: "About Me", Simple Page,
       Syllabus, Standalone Discussion board.
     - LON-CAPA standard display (tables with alternating light/darker
       gray tables) used in Construction Space and Portfolio.
     - "Global" WYSIWYG preference in "Set my user preferences" and
        single link on pages containing textareas has been eliminated
        (replaced with link to toggle for each textarea).

Authoring Resources
     - New Problem Templates:
       - Custom Response using Computer Algebra System and Hints
       - External Response
       - Drop Box
       - Input-Dependent Problems:

           - Using Learner Formula in Graph with Math Response
       - Randomized Question Stem Radio Button Response
     - Upload of HTML files with references to embedded objects etc.
         - More comprehensive feedback on reference detection.
         - Reference updates in HTML file for changed paths originally
           only available for upload of HTML file in course,
           now available for uploads in all contexts.
     - Consistent set of colors used in colorful editor.
     - Colorful editor provides insert item to wrap content within a
       problem part.
     - Optionresponse problems:
        - Can suppress display of checkbox choices.
        - Display of bullet suppressed if there is only one foil.
        - Improvements in printouts for problems with a part which
          contains multiple responses.

Student Interface
     - Portfolio: No upload to portfolio if the uploaded file is zero
       bytes in size.
     - Dropbox: Improved student interface for managing files submitted
       to dropbox over multiple tries.
       - Display of submitted files for drop box and Bridge Task
         includes warning about consequences of file deletion.
       - Clarification on how to disassociate previously submitted
         files for dropbox or Bridge Task assessment items.
     - Course Catalog will display the end date for self-enrollment
       both before and during availability of self-enrollment.
     - Fonts and icons used for the Course Contents screen are more
       compact. Icons replace the "Select Action" dropdown list.
     - Can choose to overwrite when uploading a file to the portfolio
       if a file with the same name already exists in the same path
       (unless the file is locked).
       - If the portfolio file is locked for an assignment with access
         controlled by a slot which is currently open for the user,
         overwrite is still possible.
     - If the "Course roster" is included within a course, forward and
       backward arrows are now included to permit navigation to adjacent
       course items.
     - For assignments for which collaborators can be specified:
       collaborators can be modified when new submissions are made.
     - Files submitted to dropbox items directly from the student's
       desktop instead of by selecting from the portfolio are now also
       stored in the student's portfolio (thereby allowing return of
       a version with instructor comments to the student).

     - Transactions which were to hide/unhide or delete posts do not
       contribute to the count of visible postings.
     - New set of "smileys"/emoticons. Smileys that could conflict
       with URLs and mathematical expressions disallowed.

Course/Community Management
     - Information about specific LON-CAPA version required is
       available in Course Configuration (General Settings) -
       determined by content, and parameters in use (e.g. questiontypes).
     - Course Editor
       - A tabbed interface separates editing of items in the main
         course contents area from editing of items in the (optional)
         supplemental documents area.
       - Editor Functionality is separated into: Import Documents;
         Published Resources, Special Documents and Tools. These items
         are now below the listing of resources in the current folder,
         and buttons have been replaced with icons/links.
    - Parameter Manager
       - Overview/Table Mode: List of selectable Folders includes
         indentation to show course hierarchy of folders and sub-folders;

       - Modify Mode: Radio buttons replace free form textbox to assist
         in assignment of appropriate value for "Question Type".
    - Browsing LON-CAPA shared repository: Style and icons consistent
      with listing of files in Course Contents display for a course.
    - For roles in Courses/Communities requiring a specific minimum
      LON-CAPA version, in cases where the server hosting the session
      is not running a sufficiently recent version:
      (a) If server hosting the session is running 2.10 or later, a
          link is provided for the role on roles/courses screen to switch
          to a server in the user's domain or to a server in the course's
          domain (if any have required version).
      (b) For servers hosting sessions running 2.9 or earlier, only roles which
          can be run on the version on the server hosting the session
          are available.
    - New problem modes (i.e., "questiontypes")
      - Anonymous survey (submission information not tied to
        identifiable user information).
      - Anonymous survey with credit for submission
      - Survey with credit for submission
      - New Randomization after N tries (N set as a parameter; default = 1).

      Editor) now includes a "simple numerical" type.
    - Time intervals are supported for resources for which access is
    - For case sensitive and case insensitive stringresponse problems,
      the computer's answer is available in the detailed submission display
      for each submission.
    - Groups: the link to the group homepage supports cases where the
      group homepage has an encrypted url.
    - Course Requests: now allow users without existing accounts to be
      included in course creation requests, as long as a default authentication
      type has been set for the domain.
    - Slots: for slots schedulable by student slot can set slot to
      send message(s) when student reserves slot or releases reservation.

Domain Coordination/Domain Settings
     - Domain Coordinators can control:
       (a) where their users may have sessions hosted (by internet
       domain and/or LON-CAPA version).
       (b) which other domains may have user sessions hosted on
       servers in the domain.
     - Domain configuration to set a portal or default URL, e.g., a
       loadbalancer server or a specific alias on a multidomain server.
     - Linked select boxes in course catalog can support names of
       categories for components of the institutional codes used for
       official courses which differ from the standard names: Year,
       Semester, Department, Number.
     - Number of responders to anonymous survey items required before
       displaying anonymized submission data can be set for domain.

Internals/system behavior
     - No longer stop and start firewall rules for existing hosts when
       nightly loncron connection check is made for new servers in the cluster.
     - LON-CAPA log files contain less superfluous logging (e.g., for
       non-existent metadata files).
     - LON-CAPA's Apache configuration file includes a directive for
       cacheable files which allows a user's browser to use the disk cache
       for such files served via SSL.

     - Breadcrumbs added to "Preparing Printout" and "Download PDF" pages.

     - New translations and improvements for German interface.
     - Default to English for any untranslated phrases in simplified
       Chinese interface.

     - Need for pre-2.10 "Text-based Interface Login" and
       "Accessibility Options" items eliminated by improving accessibility
       of regular pages (e.g., alt tags standard).

     - Course Coordination Manual updated to include new icons and discussion
       of redesigned general user interface.
     - Domain Coordination Manual expanded to include entries about
       access to Server Status pages, course defaults, and hosting of
