It's a few years old, but I don't think I've seen this Drupal rap video yet:

The goal of this tutorial is to show how to use Drupal 8.5's new off-canvas dialog in your own Drupal modules.

Talking about the many contributors to Drupal 8.5, a few of them shouted out on social media that they got their first patch in Drupal 8.5.

I just updated my site to Drupal 8.5 and spent some time reading the Drupal 8.5 release notes.
