Yup! The update log is mostly to keep people aware of what's going on with the revisions. If you got it with the bundle, you have to download it from the bundle page apparently.
I know because I just tested it out with something else in the bundle and it didn't let me download from the page.
Go to My Library and on the left hand side click on my purchases.
At the top, there's an option for Bundles, click on that.
You should see the Bundle for Racial Justice and Equality
Click on that, and it will bring you to the list but it should have a search feature.
Search We Used To Be Friends and the download button is there. I think you need to "claim" the download before it becomes something you can just see on the page moving forward.
