v0.4.0 Release Notes

Released 2025-07-14

Fretures

Task Dependencies

• Added support for dependent tasks, executed after other tasks are completed.
• Added multiple dependencies, allowing a task to depend on multiple preceding tasks.

Dependency Execution

• Introduced a worker pool to limit concurrent executions and reduce high-concurrency errors.

Function Extensions

• Added support for func() error for error handling in dependent tasks (mandatory for dependent tasks).
• Retained func() for tasks without dependencies.

Execution Routing

• Tasks without dependencies execute directly, while tasks with dependencies are managed via the worker pool.

Refactor

Concurrency Safety

• Added task.mutex to protect concurrent read/write of task states.
• Added dependManager.mutex to safeguard concurrent operations in the dependency manager.

Resource Management

• Implemented lifecycle management for the worker pool.
