Changes

There were several structural changes made with the release of version 2. The unique institutional settings have been split off into a new preferences.php page. This is now the page where edits need to be made to add lti key and institutional web server information.

Another structural change is the addition of the functionsLMS.php page. This page has specific functions related to accessing the LMS. This change allows for the use of PHP curl library that in turn allows for an easier way of collecting header information to be used to loop through the larger api pages and initial authentication error checking.

Additional data has been added into the topics array being saved out of the api topic call to Canvas.

Additions:

Network Graph- along with the standard graph showing connection between users, there is now an additional graph that will generate a network of posts. The posts colors identify if a post was the original to the thread or a reply. Also, isolated, unread, and late posts/replies are identified.

Previously on the user network graph when the size by word count was selected, longer post would quickly out grow all other posts and cover them up. The size is now set proportionally to the length of the smallest to largest word count using a 10 point scale.

Another key addition to Network tab is the identification of the students that have no participation.

Data Set- was pre-released under v1, but was developed along for v2.

Removed:

Matrix- this tab has been removed. Code still remains for those that want to add it back in.
