confluent-kafka-python v1.9.0

v1.9.0 is a feature release:

• OAUTHBEARER OIDC support
• KIP-140 Admin API ACL support

Fixes

• The warnings for use.deprecated.format (introduced in v1.8.2) had its logic reversed, which result in warning logs to be emitted when the property was correctly configured, and the log message itself also contained text that had it backwards. The warning is now only emitted when use.deprecated.format is set to the old legacy encoding (True). #1265
• Use str(Schema) rather than Schema.to_json to prevent fastavro from raising exception TypeError: unhashable type: 'mappingproxy'. (@ffissore, #1156, #1197)
• Fix the argument order in the constructor signature for AvroDeserializer/Serializer: the argument order in the constructor signature for AvroDeserializer/Serializer was altered in v1.6.1, but the example is not changed yet. (@DLT1412, #1263)
• Fix the json deserialization errors from _schema_loads for valid primitive declarations. (@dylrich, #989)

confluent-kafka-python is based on librdkafka v1.9.0, see the librdkafka release notes for a complete list of changes, enhancements, fixes and upgrade considerations.
