New Version 188.8.131.52 Released
This is a testing release for upcoming version 2.8. It is anticipated that
version 184.108.40.206 will be installed on production servers at MSU later
To use this release you should have version 1-12 of
LONCAPA-prerequisites installed (this is the same as for LON-CAPA 2.7).
You will need to update the version of perl-DateTime installed on your server
to perl-DateTime-0.4304-1. The repositories for the various supported
Linux distributions on http://install.loncapa.org/ have been updated with
the new package, and any associated new dependencies unavailable from core
repositories for each particular distro.
Notable Changes from 2.7.1:
- Publication is possible for problems that do not include any
response items, but include imported libraries.
- After the "Display Answer Date", Organic Material Response items
display a "Show Your Last Answer" button if a JME string for display
as the computer's answer was omitted. (In 2.7.0, but eliminated in
2.7.1 when the pencil icon replaced the "Draw Molecule" button).
- Users with a single role/course no longer have this role selected
Instead the courses/roles page will be displayed for all users after log-in.
- A "Re-initialize/Re-select" course button is shown on the
roles/courses screen for all course users when in course context.
- The WYSIWYG editor used for composing HTML in text areas has been updated
- The mimeTeX utility used to create bitmap images for display of
mathematical typesetting has been updated. Inline images now display
in vertical alignment with any surrounding text.
- For inline navigation (set to icons or icons/text) the annotations
to a resource icon will change if a user has already annotated the
- The starting day of the week used in the calendar is determined by Locale.
- Files uploaded by students for submission to assignments (e.g., via
a Drop Box) are subject to a size restriction.
- The assigned quota and the amount of disk space currently in use for
the user's Portfolio are displayed.
- System-generated text in a notification e-mail is localized
according to the recipient's language preference (or course language
preference, if message sent in course context).
- Each recipient receives a single notification e-mail if notification
e-mail and permanent e-mail addresses are the same, and e-mail should
go to both.
- The sender's e-mail address is omitted from notification e-mail
headers if the original LON-CAPA message did not permit replies. The
text of the e-mail also warns that replies will not be received by the
- The recipient type - either To: or Cc: - is preserved when
displaying a message.
Selections from both To: or Cc: recipients can be made when replying.
- A pop-up window can be launched to show a list of recipients when
displaying a message broadcast to multiple course participants.
- Group members sending a broadcast message to active group members
can elect to designate recipients as either Cc: or Bcc:.
- Ccs set in the "Contact Helpdesk" web form only apply if the form is
accessed by a logged-in user.
- The default maximum for the cumulative size of files a user can
submit to a particular question is 10 MB. Max. file size is a
parameter which can be set at a course, folder or resource level for
all users or specific users.
- Storage of information about file uploads in a course's activity log
has been streamlined.
- A file uploaded to a Drop Box is not overwritten by later submission
of a similarly named file by the same user to a different assignment.
- The naming scheme for page/sequence files which record
folder/composite page contents is more succinct where the folder/page
is a copy of an existing course item.
- If a course timezone has been defined, this will be applied to all
dates/times shown when using the "Student Activity" utility to display
recent activity in a course.
- Formularesponse items will not accept a comma in an individual
submission - either as a scalar answer or within a single component
in a vector answer (vector answers still use a comma as separator
- If timeouts or internal errors prevent grading of a submission, a
student will not be charged a try, and will be able to submit the same
- When grading bubble sheet exams, an optional verification can check
for inconsistencies between bubbled letters/numbers and stored
submissions. A scan line with anomalies receives a second grading
pass, and a warning is displayed if they persist.
- The zip file which can be generated of all files submitted by
selected students to a particular assignment now includes files
uploaded directly as well as files selected from students' portfolios.
Domain Coordination/Domain Settings
- Default Locale can be set for a domain or for a course.
- User Tools (Personal Home Page, Blogs and User Portfolio) can be
enabled/disabled for users in a domain based on affiliation (e.g.,
Faculty, Staff, Student etc.). Any domain-wide access controls can be
overridden for individual users by a Domain Coordinator. The default
is for all three tools to be enabled for all users.
- The lightweight webserver run on port 8080 (lonhttpd) formerly used
to serve icons has been eliminated because of issues with
institutional firewalls. The standard web server on port 80 (or 443
for SSL) is now used.
- Display of a banner and/or main logo on the log-in page (either
custom or default) can be disabled.
_ A Domain Coordinator's Main Menu includes a "Domain Status" item
which links to a number of utilities which provide server status
_ Access to server status pages can be configured for specific users,
or from specific IP addresses. Domain Coordinators automatically have
access for servers in their domain. This replaces the previously used
Apache Basic Auth access control.
- Generation of printouts is faster (and postscript files are smaller)
as a result of minimizing the incidence of missing fonts (which must
- The HTML paragraph tag is disabled when printing tables to prevent
hung print jobs.
- New translations and improvements were made for the German interface.
- 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
- Boxes with a thin border used to group similar items together.
