We started the "All things Drupal 9" meetings all the way back in October 2018 to start preparing for the new major release. Now in 2020, the year of Drupal 9, it was natural to make the meeting happen every Monday given the target dates coming up fast.
Contributed project maintainers, site owners, core developers are all welcome. If you are planning a Drupal 9 project for later in the year, this is your place as well. We open the floor with equal opportunity for people to propose topics, so we can cover your pressing questions as well! Join at 7pm UTC in the #d9readiness channel on Drupal Slack any Monday. The next meeting will be on January 13th, 2020.
We've been promoting Drupal 9's June 3rd 2020 target release date a lot, but that can only happen if the Drupal 9.0.0 beta requirements are all done by the end of February 2020, which is coming up real fast. There are still a lot to do and we need your help! If that does not happen, then the release will happen in August or December. While that would give less time for Drupal 8 users to update, we cannot compromise on the stability of Drupal 9 out of the gate.
