New features 2.4.9

• The new Library Browser 2 -- try it out -- will still need some graphic design tweaks.
• When creating a new homework set it is automatically assigned to the instructor creating it. You are no longer asked for permission. This prevents other extraneous errors that would sometimes occur later if the set is viewed before being assigned to someone.

Under the hood

• The names "published" and "unpublished" have been changed to "visible" and "hidden" throughout the code. Having the terms in the application code different than those presented to the user was eventually going to cause trouble (when the original programmers moved on :-) )

• This causes one potential problem because a column in the database also needs to be changed from published to visible.

Potential Gotchya's

• The RFT5746 error -- not all servers are up to date with a patch that fixes this exploit. It can cause errors on the newer firefox and chrome browsers
• after updating go to the admin page and update at least one course
• You may need to do shift reload on your browser a few times to get rid of cached javaScripts

• be sure to go to admin and update courses
  • need to add a method or a script to automatically switch published column to visible in courses
