We'll be spending the day removing deprecated code from Drupal 8 contributed modules to get them ready for Drupal 9.
Here's how you can participate! (Whether in-person or remotely!)
- Pull up the getting started info at https://tiny.cc/d9readiness and get set up with the drupal-check tool to check your code for deprecations.
- Join the #d9readiness channel on Drupal Slack.
- Check the list of issues tagged Drupal 9 compatibility + Seattle2019 (or use your own module!)
- Fix 'em and upload a patch! There are tips and tricks on the most common ones at https://github.com/mglaman/drupal-check/wiki/Deprecation-Error-Solutions, and the list of change records have the full details for any given change.
If you're a module developer who would like to "opt in" to having your module reviewed / patched by a new contributor at the sprint, please create (or find an existing) issue with the Drupal 9 compatibility + Seattle2019 tags!
