TL;DR; We’ve added a new tutorial, Upgrade to Drupal 11. And, we’ve updated all tutorials and code in our Drupal Module Developer Guide for compatibility with Drupal 11.
Upgrade to Drupal 11 is new free tutorial in the course, Upgrade Drupal, and part of our Keep Drupal Up-To-Date guide. If your site is on Drupal 10, use this tutorial to assess your site’s Drupal 11-readiness, and follow step-by-step instructions on how to upgrade your Drupal 10 site to Drupal 11.
We released our Drupal Module Developer Guide earlier in 2024 for Drupal 10 to help newcomers to modern Drupal development get hands-on practice extending Drupal using key APIs and object-oriented PHP patterns. All tutorials and example code in our Drupal Module Developer Guide have been updated for Drupal 11. The next major update we have planned for the guide is to add videos to the “task” (step-by-step) tutorials.
A special thanks to our members who make updates like these possible.
