Choosing a Version

Use 1.x if:

• You need stability and are already using the Queue API
• You cannot upgrade dependencies (SM module)
• You have custom integrations with the queue worker

Use 2.x if:

• You want modern async processing with Symfony Messenger
• You need better retry mechanisms and monitoring
• You're starting a new project
• You can handle the breaking change migration

Upgrade Path

See Breaking Changes for detailed upgrade instructions from 1.x to 2.x.

End of Life

• 1.x: Will receive security updates until Drupal 10 reaches end-of-life
• 2.x: Active development, new features

Branch Strategy

• 2.0.x: Current development (2.x)
• 1.0.x: Maintenance branch for 1.x
• Feature branches: Should target 2.0.x for new features
