New Version 2.9.0 Released

Changes from 2.8.1:

Authoring Resources

- CSS, javascript and plain text files (.css, .js, and .txt extensions) can be edited.
- Assistant Co-authors can browse directories in the repository of published resources 
  belonging to author(s) to whom they are assigned as assistant co-author.
- The "Edit Math" button (which launches a pop-up Math expression editor) is available when 
  editing HTML files.
- Adaptive hints are available for reactionresponse and organicresponse types.
- The R statistics package can be used in place of Maxima as a Computer Algebra system (CAS) 
  in mathresponse and formularesponse problems.  R can also be used to generate data sets 
  in problems by using calls to appropriate cas routines within a script block.
  Example templates are provided.
- Custom Response problems can award partial credit for problems containing multiple answers.
- In dynamic plots (GNUplot) - x and y axis zero lines can be displayed as regular lines, 
  thick lines, or as dotted lines.
- Checkbox attribute for simple two-option optionresponse type allows checkbox to be used 
  instead of two item select box (e.g., for True/False). See: SimpleTrueFalse problem template.

Student Interface

- Information about resources for which access is controlled by reservation (i.e., slots)
  is displayed on the "Table of Contents" page (renamed from "Navigate Contents").
- Students within a course can access a "Manage Reservations" utility from the Main Menu.
  This may be used to view and change reservations, and also display a log of reservation
  transactions.
- When a user initiates the reset password process for an internally authenticated account, 
  the e-mail address entered in the web form can now be any of: permanent email, critical 
  notification email or regular notification email.
- Courses with access start dates which were in the future when the student logged in, will 
  become selectable from the courses screen, once the start date has been reached, 
  without the need for logout/login.
- Course Configuration for "Grading" includes a mode to not show total parts when a student
  displays his/her grading information.

Communication

- When rendering discussion posts and other feedback for the web, new lines will no longer be 
  automatically converted to <br /> tags if HTML block elements are detected (suggesting the 
  author had used HTML originally during composition).

Course/Community Management

- A "Course/Community requests" icon is included in the "My Roles" or "My Courses" category if 
  the user has rights to create courses or communities in their home domain, and/or in another 
  domain.
- Course Configuration (previously "Set Course Environment") has been moved to the top level 
  ("Main Menu") and divided into separate sections, with permitted user input constrained by 
  radio buttons, select boxes, checkboxes, etc., in place of unrestricted entry via textboxes.
- The Course Owner can assign the Course Coordinator role in a course to other users.
- The Course Owner can declare other Course Coordinators as "Co-owners", who can choose to accept
  or deny co-ownership assignment.  (Your institution may use co-ownership to permit access to
  institutional course rosters by the automated enrollment process).  Co-owners are listed
  in the Course/Community Catalog, and can be used as a filter when searching for courses.
- Alternative titles may be specified for standard role titles (e.g., Teaching Assistant etc.) in
  a course. 
- HTML documents uploaded directly to a course can be edited by a Course Coordinator.
- The template displayed when creating custom roles depends on course type (Course or Community).
- Coordinators can require all self-enrollment requests to be approved, and can specify which 
  Coordinators should be notified when a self-enrollment request needs approval.
- Coordinators can set an enrollment limit, which when reached will prevent new self-enrollments.
- A link to the course request page is displayed after log-in if a user has no active roles, 
  and has rights to request creation of courses/communities.
- Slot reservation transactions are logged, and Coordinators/Instructors can view the history 
  of reservation changes for a particular slot from the "History" link in the slots table.
- "External" documents which may be included in a course (and display a web page from an external site
  in a frameset within LON-CAPA) are now more robust (e.g., trailing "&" trimmed from query string etc.).
- Coordinators/Instructors are warned if there is a version discrepancy if the same resource
  is used more than once in a course, and the versions are different.
- When a Coordinator uploads a file to a course, a check to determine if it is an HTML file will occur if  
  the option to look for embedded objects was checked. 

Grading

- Problems including randomlists are now supported for Bubblesheet grading (and verification).
- When grading Bridge Tasks an additional check is made for consistency of username, domain 
  and resource identifier between the grading key and the data to be submitted.
- The Bubblesheet Data Uploader's upload screen now includes a link to the syllabus for the course 
  selected to receive the data file.  A comparison is made between the student populations in the 
  course roster and in the bubblesheet data (based on student/employee ID), to try to detect 
  uploads to the wrong course.
- For Bubblesheet Data Uploaders picking a destination course, the institutional code textbox 
  is replaced with linked select boxes (e.g., year, semester, department, number), as used in 
  Course Catalog (if configured in the domain). The course owner/co-owner" row is replaced
  with "Course personnel includes: " row which can be used to search for courses where a 
  specified username:domain has active non-student role.

Domain Coordination/Domain Settings

- Firewall configuration for traffic between LON-CAPA servers now restricts
  port access to IPs for servers currently in the LON-CAPA cluster.  The nightly cron
  process which checks LON-CAPA connections will update the firewall for any
  changes in membership of the cluster.
- Display of the log-in page for specific servers in a domain can be replaced by 
  automatic redirection to a different server (e.g., to a LON-CAPA load balancer server, 
  used solely for authentication and session switching).
- Domain Coordinators can modify institutional status for users in their domain.
- A new configuration is available to set which users may request creation of: 
  (a) official courses, (b) unofficial courses, or (c) communities. 
- Communities are similar to courses except the Coordinator may only browse areas
  of the shared LON-CAPA repository for which he/she has an author or co-author role.
- Course/Community requests may be set to be processed automatically, queued for approval 
  by a Domain Coordinator, or (for official courses) validated against the institutional 
  instructor of record.
- Domain Coordinators can permit course requests to be made by users from other domains,
  on a user-by-user basis.
- A Domain Coordinator can set which affiliations within the institution (e.g., Faculty, Staff etc.) 
  may create his/her own account (applies to institutional login/SSO only). 
- The course creation menu includes additional links: (a) display course requests queued 
  pending approval by a Domain Coordinator; (b) display requests for official courses queued 
  pending institutional validation; (c) display a log of course creation history.
- The "Edit this resource" link is displayed to a Domain Coordinator in course context, 
  if the domain of the resource author is the domain of the current role.
- The aggregate database of courses in a domain used when searching for a course (e.g., 
  when selecting an ad hoc role, choosing a course to clone etc.) is rebuilt nightly 
  by cron from permanent data stored in each course's environment.db file.
- Domain Coordinators may filter by time elapsed since course creation when using the 
  course picker (e.g., to select an ad hoc role, assign a Course Coordinator role etc.).
- A domain may be configured to automatically assign co-ownership status when a Course
  Coordinator role becomes active in an official course, if the Coordinator is official
  course personnel (requires customization of localenroll.pm).
- Domain Coordinators may delete entries in personal information fields (i.e., name, 
  permanent e-mail address) if a value has been set previously.
- Domain Coordinators may allow users to choose (via a User Preference) to prevent updates to 
  information fields by a nightly automated update which synchronizes LON-CAPA with institutional
  directory data.
- Nightly removal of stale files in /home/httpd/perl/tmp will descend into sub-directories and also
  remove stale files from them.
  
Printing

- Printouts of PDF files within a folder (both in a course and in Construction Space) can
  be generated.
- The default font size in printouts can be set by Course Coordinators and Authors/Co-authors.
- Composite pages (.page) can be printed in Construction Space and also printed with answers.
- Composite pages (.page) containing numerical problems can be printed when set to exam mode.
- Composite pages (.page) can be printed for selected students.
- The syllabus can be printed when generating printouts of resources for selected students.
- Printing of tables has been standardized to use the perl LaTeX::Table module.

Localization

- New translations and improvements are provided for both the German and Spanish interfaces.
- UTF-8 encoding is used for all browsers (including Internet Explorer).
- The time zone of the local server is cached, and translations of phrases are also cached 
  to improve performance.

Accessibility
- An alt attribute (which includes the raw TeX) is supplied for use by screen readers when 
  MimeTex images are used to render math expressions.
- Raw mode (will output raw TeX) is available as an additional option for rendering math 
  expressions.

Appearance
- More interface standardization using the following display elements:
   - Data tables with rows of alternating light/dark background colors, and a colored header.
   - Two column data tables with a colored left column, and light gray right column.
   - Boxes with a thin border used to group similar items together.
- More muted colors, and standard data table used for Roles/Courses screen.
