New Version 2.7.1 Released

This is primarily a bug fix release for version 2.7.0
It is highly recommended to update 2.7.0 installations with 2.7.1

To use this release you need to have version 1-12 of LONCAPA-prerequisites
installed.

If you are upgrading directly from 2.6.3 or earlier, the next  
paragraph applies to you:

   One of the changes for 2.7 affects scantronformat.tab. After you  
have installed 2.7.1 on the primary library server in your domain,  
log-in, select the Domain Coordinator role, and go to "Domain  
Configuration". Check the box for "Scantron format file", click "Go",  
and if you currently use a customized scantronformat.tab file it will  
be copied (behind the scenes) from its current location to a new  
location where it will be available for selection whenever scantron  
grading is used in a course in your domain.  Refer to the 2.7.0  
release notes -  
http://mail.lon-capa.org/pipermail/lon-capa-announce/2008/000061.html  
- for information about changes between 2.6.3 and 2.7.0.

Changes from 2.7.0

Bug fixes for 2.7.0-specific bugs

- Dynamically generated plots are rendered again where a value has  
been included for the minorfreq in the ytics tag.
- Resources in a folder are available again for selection when  
printing the contents of a folder in Construction Space.
- Generation of printouts works again for vector problems for which  
multiple answers are required, but some have not been submitted.
- Domain Coordinators can again select co-author roles assigned to  
them in other domains.
- Spaces included in submissions to stringresponse problems are again  
retained when grading.
- Stringresponse problems, for which a type (cs, ci, mc or re) has not  
been set, are again graded correctly in cases where the first or  
second character in the submitted string is a number.
- A list of accessible portfolio files can again be reached from a  
user's personal web page ("aboutme" page).

Bug fixes for other general bugs

- Complete breadcrumb trail now provided to students viewing  
Supplemental Documents, thereby allowing access to top level items,  
once items deeper in the hierarchy have been viewed.
- Pasting an item from Supplemental Documents to Main Documents no  
longer results in artifacts from HTML tags in the item title.
- More comprehensive format checking is used for usernames of  
collaborators in problems allowing submission by teams of students.
- Parameter Helper and Slot Manager now include current time zone when  
setting dates/times.
- Testbank importer in Construction space now displays an error  
message (including type of file uploaded) if the file was not plain  
text, RTF or HTML.
- Problems set to type "Practice" are available for selection when  
printing just problems from a folder.
- The broadcast e-mail utility for Domain Coordinators will now  
convert usernames for locally authenticated users to e-mail addresses  
if a generic suffux (e.g., msu.edu) is provided.
- Automatic offloading of sessions from an overloaded server to a  
server listed in spare.tab now supported where the destination server  
uses SSL, if https has been included as an additional entry in the  
dns_hosts.tab for that server (send updates to loncapa at loncapa.org).
- Access to submissions for problems with encrypted URLs from links in  
the course assessment progress chart (CHRT) now works for TAs.
- Display of problems with encrypted URLs now works for TAs when using  
"View" links available for some items in "course assessment  
statistics" (STAT).


Enhancements
- "Edit Answer" button used to open a pop-up DragMath, JME Editor, or  
Chemical reaction Editor pop-up window replaced with a pencil icon to  
the right of the text box used to enter the answer.
- A new parameter is provided to hide the DragMath WYSIWYG Math Editor  
(default is for the icon to be visible) for Mathresponse and  
Formularesponse items.
- Access control based on IP address extended to other resources in a  
course besides problems.
- Algebra tag can include a display attribute to dictate which math  
rendering (tth, jsMath, mimetex) is to be used.
- Disply of events in the calendar now consistent with current time  
zone (included in Calendar header line).
- Instructional staff can generate printouts from the entire course  
for selected people.
- Launch Remote Control (RC) link moved from inline navigation menu to  
reduce congestion (all users not currently using the RC will launch it  
from User Preferences).
- Authors can assign more than one target language for a particular  
<lang> block when creating multilingual resources.

To install this update:

1) You will need to be running Fedora Core 6, 7, 8, or 9, RHEL (AS|ES) 4 or 5,
     SUSE 10.1 10.2 or 10.3, SLES 9 or 10, CentOS 5, Scientific Linux 5
       (Fedora Core 5 should continue to work but is deprecated.)

2) Update to the latest LONCAPA-prerequisites (1-12)
    (skip if upgrading from 2.7.0)

(a) Fedora
yum update

(b) RedHat Enterprise 4

up2date -u LONCAPA-prerequisites

Note: LONCAPA-prerequisites for Red Hat Enterprise Linux 4 includes
a dependency on perl-libxml-enno-1.03.  If you already have perl-libxml-enno
installed on your system it will be version 1.02 unless already updated.
If the update to LONCAPA-prerequisites 1-12 fails to update  
perl-libxml-enno to 1.03, you should update that package directly:

up2date -u perl-libxml-enno

(c) Red Hat 5/Centos 5/Scientific Linux 5

yum update

(d) SuSE/SLES

Use yast-> Installation Source to refresh the LON-CAPA repository
Use yast->Software Management->Search to update LONCAPA-prerequisites (to
version  1-12).

For SLES9, use yast->Software Management->Search to also update latex-ucs
(to version 20041017-31) after refreshing the LON-CAPA repository.

On all distributions, it is recommended that you check that you have the
correct versions of LONCAPA-prerequisites installed before proceeding.

rpm -q LONCAPA-prerequisites

should report:
LONCAPA-prerequisites-1-12.X

(where X is a distro identifier e.g., fc7.lc)

If you are using Red Hat 4, also check that you have
perl-libxml-enno version 1.03

rpm -q perl-libxml-enno

should report:
perl-libxml-enno-1.03-1.rhel4.lc

3) Download the new LON-CAPA tarball from
wget http://install.lon-capa.org/versions/loncapa-2.7.1.tar.gz

and untar it

tar xzvf loncapa-2.7.1.tar.gz

4) stop the LON-CAPA system services

/etc/rc.d/init.d/loncontrol stop

5) stop the webserver:

Fedora/RHEL/Centos/Scientific Linux
/etc/rc.d/init.d/httpd stop

SLES 9:
/etc/init.d/apache stop

SUSE 10.1/SLES 10:
/etc/init.d/apache2 stop


6) Run the UPDATE script as root
cd loncapa-2.7.1
su
./UPDATE

Fedora/RHEL/Centos/Scientific Linux
