Users running a non-download version of Vanilla (pulled from github), on branch release/2019.016 or master from the last 2 weeks should upgrade to release/2019.017 or latest master for security reasons. Downloaded official open sources releases are not affected.
When viewing a Draft, the "Cancel" link is basically functionless and there's no "Delete". I just had a very confusing 2 minutes during which I could not figure out how to delete a draft. I was clicking on it in the sidebar and clicking the "Cancel" button to try and make it go away. I had to step back and think about how to make them all appear on one page (Discussions -> Drafts) in the hopes that more options would appear, which did work, but I worry that casual users might not make that leap.
