v5.6.0

Key Highlights

QoS Max Prefetch Limit celery/kombu#2348

Prevent Out Of Memory crashes when queues flood with ETA/countdown tasks. The new optional max_prefetch parameter caps how many messages workers hold in memory. Defaults to unlimited (None) to preserve existing behavior.

from kombu.common import QoS
Limit prefetch to maximum 100 messages
qos = QoS(callback=consumer.qos, initial_value=10, max_prefetch=100)

Redis Polling Interval Support celery/kombu#2346

Fix Redis transport to properly propagate polling_interval and brpop_timeout from transport_options to the Channel's _brpop_start timeout.

app.conf.broker_transport_options = {"polling_interval": 10}
