Celery v5.6.0 is now available.

Key Highlights

See What's new in Celery 5.6 for a complete overview or read the main highlights below.

Python 3.9 Minimum Version

Celery 5.6.0 drops support for Python 3.8 (EOL). The minimum required Python version is now 3.9. Users still on Python 3.8 must upgrade their Python version before upgrading to Celery 5.6.0.

Additionally, this release includes initial support for Python 3.14.

SQS: Reverted to pycurl from urllib3

The switch from pycurl to urllib3 for the SQS transport (introduced in Celery 5.5.0 via Kombu) has been reverted due to critical issues affecting SQS users.

Contributed by @auvipy in #9620.

Security Fix: Broker Credential Leak Prevention

Fixed a security issue where broker URLs containing passwords were being logged in plaintext by the delayed delivery mechanism. Broker credentials are now properly sanitized in all log output.

Contributed by @giancarloromeo in #9997.

Memory Leak Fixes

Two significant memory leaks have been fixed in this release:

Exception Handling Memory Leak: Fixed a critical memory leak in task exception handling that was particularly severe on Python 3.11+ due to enhanced traceback data. The fix properly breaks reference cycles in tracebacks to allow garbage collection.

Contributed by @jaiganeshs21 in #9799.

Pending Result Memory Leak: Fixed a memory leak where AsyncResult subscriptions were not being cleaned up when results were forgotten.

Contributed by @tsoos99dev in #9806.

ETA Task Memory Limit

New configuration option worker_eta_task_limit to prevent out-of-memory crashes when workers fetch large numbers of ETA or countdown tasks. Previously, workers could exhaust available memory when the broker contained many scheduled tasks.

Example usage:

app.conf.worker_eta_task_limit = 1000

Contributed by @sashu2310 in #9853.

Queue Type Selection for Auto-created Queues

New configuration options allow specifying the queue type and exchange type when Celery auto-creates missing queues. This is particularly useful for RabbitMQ users who want to use quorum queues with auto-created queues.

Configuration options:

• task_create_missing_queue_type: Sets the queue type for auto-created queues (e.g., quorum, classic)
• task_create_missing_queue_exchange_type: Sets the exchange type for auto-created queues

Example usage:

app.conf.task_create_missing_queue_type = 'quorum'

Contributed by @ghirailghiro in #9815.

Celery v5.5.0 is now available.

Key Highlights

See What's new in Celery 5.5 for a complete overview or read the main highlights below.

Redis Broker Stability Improvements

Long-standing disconnection issues with the Redis broker have been identified and resolved in Kombu 5.5.0, which is included with this release. These improvements significantly enhance stability when using Redis as a broker.

Additionally, the Redis backend now has better exception handling with the new exception_safe_to_retry feature, which improves resilience during temporary Redis connection issues. See Redis backend settings for complete documentation.

Contributed by @drienkop in #9614.

pycurl replaced with urllib3

Replaced the pycurl dependency with urllib3.

We're monitoring the performance impact of this change and welcome feedback from users who notice any significant differences in their environments.

Contributed by @spawn-guy in Kombu #2134 and integrated in Celery via #9526.

RabbitMQ Quorum Queues Support

Added support for RabbitMQ's new Quorum Queues feature, including compatibility with ETA tasks. This implementation has some limitations compared to classic queues, so please refer to the documentation for details.

Native Delayed Delivery is automatically enabled when quorum queues are detected to implement the ETA mechanism.

See Using Quorum Queues for complete documentation.

Configuration options:

• broker_native_delayed_delivery_queue_type: Specifies the queue type for delayed delivery (default: quorum)
• task_default_queue_type: Sets the default queue type for tasks (default: classic)
• worker_detect_quorum_queues: Controls automatic detection of quorum queues (default: True)

Contributed in #9207, #9121, and #9599.

For details regarding the 404 errors, see New Year's Security Incident.

Soft Shutdown Mechanism

Soft shutdown is a time limited warm shutdown, initiated just before the cold shutdown. The worker will allow worker_soft_shutdown_timeout seconds for all currently executing tasks to finish before it terminates. If the time limit is reached, the worker will initiate a cold shutdown and cancel all currently executing tasks.

This feature is particularly valuable when using brokers with visibility timeout mechanisms, such as Redis or SQS. It allows the worker enough time to re-queue tasks that were not completed before exiting, preventing task loss during worker shutdown.

See Stopping the worker for complete documentation on worker shutdown types.

Configuration options:

• worker_soft_shutdown_timeout: Sets the duration in seconds for the soft shutdown period (default: 0.0, disabled)
• worker_enable_soft_shutdown_on_idle: Controls whether soft shutdown should be enabled even when the worker is idle (default: False)

Contributed by @Nusnus in #9213, #9231, and #9238.

Pydantic Support

New native support for Pydantic models in tasks. This integration allows you to leverage Pydantic's powerful data validation and serialization capabilities directly in your Celery tasks.

Example usage:

from pydantic import BaseModel
from celery import Celery

app = Celery('tasks')

class ArgModel(BaseModel):
    value: int

class ReturnModel(BaseModel):
    value: str

@app.task(pydantic=True)
def x(arg: ArgModel) -> ReturnModel:
    # args/kwargs type hinted as Pydantic model will be converted
    assert isinstance(arg, ArgModel)

    # The returned model will be converted to a dict automatically
    return ReturnModel(value=f"example: {arg.value}")

See Argument validation with Pydantic for complete documentation.

Configuration options:

• pydantic=True: Enables Pydantic integration for the task
• pydantic_strict=True/False: Controls whether strict validation is enabled (default: False)
• pydantic_context={...}: Provides additional context for validation
• pydantic_dump_kwargs={...}: Customizes serialization behavior

Contributed by @mathiasertl in #9023, #9319, and #9393.

Google Pub/Sub Transport

New support for Google Cloud Pub/Sub as a message transport, expanding Celery's cloud integration options.

See Google Pub/Sub Transport for complete documentation.

For the Google Pub/Sub support you have to install additional dependencies:

$ pip install "celery[gcpubsub]"

Then configure your Celery application to use the Google Pub/Sub transport:

broker_url = 'gcpubsub://projects/project-id'

Contributed by @haimjether in #9351.

Python 3.13 Support

Official support for Python 3.13. All core dependencies have been updated to ensure compatibility, including Kombu and py-amqp.

This release maintains compatibility with Python 3.8 through 3.13, as well as PyPy 3.10+.

Contributed by @Nusnus in #9309 and #9350.

REMAP_SIGTERM Support

The "REMAP_SIGTERM" feature, previously undocumented, has been tested, documented, and is now officially supported. This feature allows you to remap the SIGTERM signal to SIGQUIT, enabling you to initiate a soft or cold shutdown using TERM instead of QUIT.

This is particularly useful in containerized environments where SIGTERM is the standard signal for graceful termination.

See Cold Shutdown documentation for more info.

To enable this feature, set the environment variable:

export REMAP_SIGTERM="SIGQUIT"

Contributed by @Nusnus in #9461.

Database Backend Improvements

New create_tables_at_setup option for the database backend. This option controls when database tables are created, allowing for non-lazy table creation.

By default (create_tables_at_setup=True), tables are created during backend initialization. Setting this to False defers table creation until they are actually needed, which can be useful in certain deployment scenarios where you want more control over database schema management.

See Database backend settings for complete documentation.

Configuration:

app.conf.result_backend = 'db+sqlite:///results.db'
app.conf.database_create_tables_at_setup = False

Contributed by @MarcBresson in #9228.

Using Kombu 5.5.0rc3

The minimum required Kombu version has been bumped to 5.5.0.
Kombu is currently at 5.5.0rc3.

Complete Quorum Queues Support

A completely new ETA mechanism was developed to allow full support with RabbitMQ Quorum Queues.

After upgrading to this version, please share your feedback on the quorum queues support.

Relevant Issues: #9207, #6067

• New documentation.
• New broker_native_delayed_delivery_queue_type configuration option.

New support for Google Pub/Sub transport

After upgrading to this version, please share your feedback on the Google Pub/Sub transport support.

Relevant Issues: #9351

Python 3.13 Improved Support

Additional dependencies have been migrated successfully to Python 3.13, including Kombu and py-amqp.

Soft Shutdown

The soft shutdown is a new mechanism in Celery that sits between the warm shutdown and the cold shutdown. It sets a time limited "warm shutdown" period, during which the worker will continue to process tasks that are already running. After the soft shutdown ends, the worker will initiate a graceful cold shutdown, stopping all tasks and exiting.

The soft shutdown is disabled by default, and can be enabled by setting the new configuration option worker_soft_shutdown_timeout. If a worker is not running any task when the soft shutdown initiates, it will skip the warm shutdown period and proceed directly to the cold shutdown unless the new configuration option worker_enable_soft_shutdown_on_idle is set to True. This is useful for workers that are idle, waiting on ETA tasks to be executed that still want to enable the soft shutdown anyways.

The soft shutdown can replace the cold shutdown when using a broker with a visibility timeout mechanism, like Redis or SQS, to enable a more graceful cold shutdown procedure, allowing the worker enough time to re-queue tasks that were not completed (e.g., Restoring 1 unacknowledged message(s)) by resetting the visibility timeout of the unacknowledged messages just before the worker exits completely.

After upgrading to this version, please share your feedback on the new Soft Shutdown mechanism.

Relevant Issues: #9213, #9231, #9238

• New documentation for each shutdown type.
• New worker_soft_shutdown_timeout configuration option.
• New worker_enable_soft_shutdown_on_idle configuration option.

REMAP_SIGTERM

The REMAP_SIGTERM "hidden feature" has been tested, documented and is now officially supported.
This feature allows users to remap the SIGTERM signal to SIGQUIT, to initiate a soft or a cold shutdown using TERM
instead of QUIT.

Pydantic Support

This release introduces support for Pydantic models in Celery tasks.
For more info, see the new pydantic example and PR #9023 by @mathiasertl.

After upgrading to this version, please share your feedback on the new Pydantic support.

Redis Broker Stability Improvements

The root cause of the Redis broker instability issue has been identified and resolved in the v5.4.0 release of Kombu, which should resolve the disconnections bug and offer additional improvements.

After upgrading to this version, please share your feedback on the Redis broker stability.

Relevant Issues: #7276, #8091, #8030, #8384

Quorum Queues Initial Support
