New Version 2.6.2 Released 

This is primarily a bug fix release for versions 2.6.0 and 2.6.1
It is highly recommended to update 2.6.0 or 2.6.1 installations with 2.6.2 
if LON-CAPA is used for scantron grading in your domain. 

Changes from 2.6.1 

Bug fixes:
 - Validation of scantron files again accommodates optionresponse, 
matchresponse and rankresponse problems (multiple bubble lines are used in a 
single problem in these cases).
 - Bridge Tasks to be graded are again listed as items for handgrading in the 
What's New page.
 - Edit XML and Edit links for a file in a directory listing in Construction
Space go directly to the corresponding edit screen, again, as expected.
 - Day of the week is now correct when language preference is not English.
 - LaTeX jobs stuck in a loop now timeout and cease to consume processor
 - When cloning a course, usernames set in course parameters (e.g.,
recipients of messages about course policy, content etc.) are no longer
copied to the new course.
 - Link/Button to access Construction Space now added to Main Menu/Remote
Control for Assistant Co-authors.
 - A table of contents is available again in the PDF version of the Author 

 - Practice problems are marked as "not graded" in a course's table of
 - Solution of a practice problem results in a message that "submissions for
practice problems are not preserved" instead of a receipt.
 - Resources can be printed with associated annotations made by the user.
 - The problem type (exam, survey or homework) can be specified when printing 
a problem in Construction Space.
 - Some localization updates.
 - Some German translations added or updated.
