v1.0.16

[1.0.16] - 2026-07-31

Added

• datacontract test reads the Avro schema of a Kafka topic from the Confluent Schema Registry via DATACONTRACT_KAFKA_SCHEMA_REGISTRY_URL, DATACONTRACT_KAFKA_SCHEMA_REGISTRY_USERNAME, and DATACONTRACT_KAFKA_SCHEMA_REGISTRY_PASSWORD (#1347)

Deprecated

• DATACONTRACT_SNOWFLAKE_PRIVATE_KEY_PATH, DATACONTRACT_SNOWFLAKE_PRIVATE_KEY_PASSPHRASE, and DATACONTRACT_SNOWFLAKE_CONNECTION_TIMEOUT: use DATACONTRACT_SNOWFLAKE_PRIVATE_KEY_FILE, DATACONTRACT_SNOWFLAKE_PRIVATE_KEY_FILE_PWD, and DATACONTRACT_SNOWFLAKE_LOGIN_TIMEOUT instead
• DATACONTRACT_SQLSERVER_TRUSTED_CONNECTION: use DATACONTRACT_SQLSERVER_AUTHENTICATION=windows instead

Fixed

• datacontract test against a Kafka topic reports Avro messages it cannot decode as such, instead of reading every field as null (#1347)
• datacontract test connects to Databricks with an OAuth service principal again, instead of failing with Error during request to server on databricks-sql-connector 4.3.0 and later (#1389)
• DATACONTRACT_SQLSERVER_TRUSTED_CONNECTION no longer overrides an explicitly set DATACONTRACT_SQLSERVER_AUTHENTICATION, so a leftover flag cannot silently downgrade an Entra ID login to Windows authentication
• datacontract test passes DATACONTRACT_IMPALA_AUTH_MECHANISM, DATACONTRACT_IMPALA_USE_HTTP_TRANSPORT, and DATACONTRACT_IMPALA_HTTP_PATH to Impala again, so a Cloudera Virtual Warehouse can be reached instead of failing with TSocket read 0 bytes
• datacontract test passes the servers block catalog to Athena again, instead of always querying awsdatacatalog
• datacontract test supports DATACONTRACT_BIGQUERY_IMPERSONATION_ACCOUNT again to impersonate a service account
• datacontract test applies the documented Snowflake key-pair and timeout variables instead of silently ignoring them: the names they were documented under are not accepted by the Snowflake driver, and now map to the ones that are
• datacontract dbt sync does not assume severity: warn as default anymore: tests now fail with dbt's default severity unless the contract declares a non-blocking quality.severity
• datacontract dbt sync no longer drops or misplaces YAML comments that introduce the next column, test, or key
