0.2.0 - 2026-02-13

🏗️ Design Changes

• Nested Tasks Redesign: We change how nested task (like task in a chain) alert the parent task on status change. This will help save a lot of memory in redis and have faster execution. For that we added:
  • Container sub-task hooks: and abstract methods on for handling child task lifecycle events.
  • BREAKING - Removed from : Replaced by for parent reference.

✨ Added

• ** method**: Add and schedule a task in a running swarm in a single call, replacing the previous + two-step pattern.
• Chain kwargs forwarding: Chains now accept that are forwarded to all sub-tasks during execution.

🔄 Changed

• BREAKING - Removed : Swarm tasks are no longer wrapped in batch item signatures. Tasks run directly within the swarm.
• BREAKING - Removed from swarm: Use instead.
• BREAKING - Removed from : Callbacks are now set at creation time only.
• All internal tasks are durable: Chain and swarm infrastructure tasks now use for crash recovery.

🛠️ Technical Improvements

• Task data parameter consolidation: Only is sent as task metadata instead of a full dictionary. This will allow users to filter workflow base on task id and will save data that is sent in tasks.

🧪 Tests

• Unit tests for handle decorator: Added comprehensive tests for decorator.
• Unit tests for signature creation: Added tests for and .
