• Added support for unique jobs. Passing unique=True with job_id prevents duplicate jobs from being enqueued or scheduled. Thanks @selwin!
• Result now stores execution metadata (execution_id, execution_started_at and execution_ended_at). Thanks @selwin!
• Retry now supports enqueue_at_front=True, allowing retried jobs to be requeued at the front of the queue. Thanks @crazillagodzilla!
• Custom job_id values may only contain letters, numbers, underscores and dashes. Thanks @selwin!
• When a job is stopped, its dependencies are no longer enqueued. Thanks @selwin!
• DeferredJobRegistry is now scored by job creation time. Thanks @selwin!
• Workers now print a warning instead of raising an exception when CLIENT LIST is not supported. Thanks @selwin and @djmaze!
