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.

Upgrade considerations

OpenSSL 3.0.x upgrade in librdkafka requires a major version bump, as some
legacy ciphers need to be explicitly configured to continue working,
but it is highly recommended NOT to use them. The rest of the API remains
backward compatible.

confluent-kafka-python is based on librdkafka v2.0.2, see the
librdkafka v2.0.0 release notes
and later ones for a complete list of changes, enhancements, fixes and upgrade considerations.

Note: There were no v2.0.0 and v2.0.1 releases.
