Drupal 10's release date is targeted for December 2022 (as of August 2022), and the CiviCRM community anticipates providing support for it around the time of its release.

 Drupal 9 sites are typically administered with [Composer](https://www.getcomposer.org). Composer is a *dependency management* tool which can add, upgrade, and remove software *packages* for your site.
 
 CiviCRM is published as a suite of related packages. Our goal is to use Composer to add CiviCRM's packages to the D9 site.

 **Drupal** is the most flexible and has the best integration with CiviCRM. If you have complex CMS needs or envisage a lot of interaction between users on your website and your CRM, then Drupal might be the CMS for you. The main negative is that this flexibility makes it harder for new site builders to get to grips with.
 
-**Backdrop CMS** is very similar to Drupal 7, with many improvements making it slick and lightweight. It started as a fork (that is, a copy) of Drupal 7, aimed at users for whom Drupal 9 was likely to be too complex either to use, or to migrate to from Drupal 7. Drupal 7 modules and themes require modifications to work with Backdrop CMS, though many have already been ported and are actively maintained.

 **Joomla** isn't as popular as WordPress, though it is more popular than Drupal. Joomla is easier to learn than Drupal. The amount of integration available is lower than then when using Drupal.
