Release Highlights

Quality Improvements and Stability Enhancements

Celery 5.3 focuses on elevating the overall quality and stability of the project. We have dedicated significant efforts to address various bugs, enhance performance, and make improvements based on valuable user feedback.

Better Compatibility and Upgrade Confidence

Our goal with Celery 5.3 is to instill confidence in users who are currently using Celery 4 or older versions. We want to assure you that upgrading to Celery 5.3 will provide a more robust and reliable experience.

Dropped support for Python 3.7

Celery now requires Python 3.8 and above.

Python 3.7 will reach EOL in June, 2023. In order to focus our efforts we have dropped support for Python 3.6 in this version.

If you still require to run Celery using Python 3.7 you can still use Celery 5.2. However we encourage you to upgrade to a supported Python version since no further security patches will be applied for Python 3.7 after the 23th of June, 2023.

Automatic re-connection on connection loss to broker

Unless :setting:broker_connection_retry_on_startup is set to False, Celery will automatically retry reconnecting to the broker after the first connection loss. :setting:broker_connection_retry controls whether to automatically retry reconnecting to the broker for subsequent reconnects.

Since the message broker does not track how many tasks were already fetched before the connection was lost, Celery will reduce the prefetch count by the number of tasks that are currently running multiplied by :setting:worker_prefetch_multiplier. The prefetch count will be gradually restored to the maximum allowed after each time a task that was running before the connection was lost is complete
