Overview

Celery 5.6, released on November 30, 2025, adds Python 3.14 support and drops Python 3.8.

Main Features

Python 3.14 and 3.8 dropped

Celery 5.6 is compatible with Python 3.14 and drops Python 3.8 support, allowing the codebase to be modernized.

python 
from celery import Celery

app = Celery('demo', broker='redis://localhost:6379/0')

@app.task
def add(x, y):
    return x + y

# Async call
result = add.delay(4, 6)
print(result.get(timeout=10))  # 10

Backend improvements

The result backend has been optimized to reduce get() call latency and improve Redis connection handling.
