Besides the fancy new logo, most notably, we've upgraded the AutoPublish feature.
Upgraded AutoPublish Feature
So once you write an interactive tutorial of your own or customize an existing CALI Lesson, you can, as the AutoPublish name suggests, automatically publish it to the CALI website.
Once you publish the lesson to our website using the AutoPublish feature in CALI Author, you'll get a unique URL. You can pass this URL on to your students so they can run your AutoPublished lesson. You can even track who has used your creation and what they scored within your CALI AutoPublish account (login, righthand menu > CALI AutoPublish).
