Droost Framework's first stable releases came out together on 27 October 2026.

Droost UI Kit 2.0.0 composer require --dev 'drupal/droost_ui_kit:^2.0' (with droost and droost_build) drupal.org

Why the module is 2.0 and the command 1.0

The module's releases come from its 2.x branch, which rebuilt it on Tool API, so its first stable release is 2.0.0. Droost UI Kit follows the module's numbering. The command, the engine, the recipe and the theme start at 1.0.0.

Tool API is still beta

Tool API has no stable release yet, so a site requires it at beta stability itself ('drupal/tool:^1.0@beta'): Composer ignores a dependency's own stability flags.

Coming from before 2.0

Droost 1.x is deprecated and unsupported, and the 2.0 alphas cannot be upgraded in place. See Upgrading.

Droost UI Patterns is obsolete: it continues as Droost UI Kit.
