Many have asked for it, now it's here. Lacuna v2.3 supports PDF annotation! When creating a new document, you can upload PDFs instead of text and your students can now annotate anywhere on the PDF. You can even include images in the PDF. Thanks go out to Cody Leff for adding this exciting new feature.
Another notable feature is our new "Latest Conversations" page, which places all the interactions from other students in one place. Did somebody reply to your annotation? Did they comment on your response? If so, you can see all of it from this page. Thanks to Daniel Bush for creating this new system.
Lacuna v2.3 includes many minor fixes, updates, and more. You can check out our release notes for the full run-down.
