v2.6.2

confluent-kafka-python v2.6.2

Warning

Due to an error in which we included dependency changes to a recent patch release, Confluent recommends users to refrain from upgrading to 2.6.2 of Confluent Kafka. Confluent will release a new minor version, 2.7.0, where the dependency changes will be appropriately included. Users who have already upgraded to 2.6.2 and made the required dependency changes are free to remain on that version and are recommended to upgrade to 2.7.0 when that version is available. Upon the release of 2.7.0, the 2.6.2 version will be marked deprecated.
We apologize for the inconvenience and appreciate the feedback that we have gotten from the community.

Note: This version is yanked from PyPI. Use 2.7.0 instead.

for a complete list of changes, enhancements, fixes and upgrade considerations.

v2.5.0

Warning

This version has introduced a regression in which an assert is triggered during PushTelemetry call. This happens when no metric is matched on the client side among those requested by broker subscription.

You won't face any problem if:

• Broker doesn't support KIP-714.
• KIP-714 feature is disabled on the broker side.
• KIP-714 feature is disabled on the client side. This is enabled by default. Set configuration enable.metrics.push to false.
• If KIP-714 is enabled on the broker side and there is no subscription configured there.
• If KIP-714 is enabled on the broker side with subscriptions that match the KIP-714 metrics defined on the client.

Having said this, we strongly recommend using v2.5.3 and above to not face this regression at all.
