Warning: A data formatting change in the grading queues and slot
definitions has occurred compared to versions prior to If
you upgrade from a version prior to you will need to upgrade
all servers simultaneously. (No performance data will be lost. It's
just if a user submits an answer to an essay problem on a post-2.1
access server, but the instructor accesses the grading queue from a
2.1 server, the student won't appear in the queue. After the update is
installed the student will appear in the queue.)

Please read the update procedure. We now suggest stopping both the
webserver and Lon-CAPA services before running the update script.

To install this update:

1) You will need to be running Fedora Core 4 or 5, RHEL ES 4, SUSE 9.3, SLES 9
     (Fedora Core 3 should continue to work but is deprecated.)

2) If running Fedora, use yum to update your machine and then install the
      LONCAPA-prerequisites (if not already installed).

yum update
yum install LONCAPA-prerequisites

    If running SUSE, use you to update your machine.
    if running RHEL, use up2date to update your machine.

3) Download the new LON-CAPA tarball from
wget http://install.lon-capa.org/versions/loncapa-2.2.0.tar.gz

and untar it

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