I presented The Drupal 10 readiness initiative - here we go at DrupalCon Europe a month ago. While I published my slides with plenty speaker notes right away, the session videos just became public. While the live presentation was a month ago, most of the content is still up to date.
Drupal 9 is expected to have the shortest Drupal major release lifetime in recent history with Drupal 10 planned to be released in the middle of 2022 (next year!) and Drupal 9 end of life by end of 2023. In this session, we discussed what it takes to get from Drupal 9 to Drupal 10 and how are we going to manage this transition. We also covered what we learned from the Drupal 8 to 9 transition (so far) and how we plan to make it better for 10.
