v1.0.4

[1.0.4] - 2026-06-22

Added

• datacontract test validates Azure Blob Storage / ADLS Gen2 file metadata against a data contract used as a storage policy (#1227)
• datacontract test against Trino now supports DATACONTRACT_TRINO_AUTHENTICATION=jwt with DATACONTRACT_TRINO_JWT_TOKEN, and DATACONTRACT_TRINO_AUTHENTICATION=oauth2 for the interactive browser flow.
• datacontract export sql --dialect clickhouse: export data contracts to ClickHouse SQL DDL. (#1293)
• Example data contracts and import sources under examples/, used as the worked examples on the docs export and import pages.

Fixed

• datacontract import unity now imports struct and array columns as structured ODCS types instead of only a flat type string: structs get nested properties, arrays get items (parsed recursively from Unity's type_json, including descriptions on nested fields). Arrays also get the correct logicalType: array (previously object); this logical type fix applies to the sql and snowflake importers as well. Map columns and other unmappable SQL types now leave logicalType unset (instead of the invalid object) until ODCS v3.2 adds logicalType: map (RFC 0030). (#1280)
• datacontract export dcs no longer crashes on data contracts with a structured description or a standard server.
• datacontract test against Oracle releases before 23ai no longer fails every check with ORA-00923: FROM keyword not found where expected during schema introspection.
• datacontract test now recognizes Oracle VARCHAR2/NVARCHAR2 (with or without a length, e.g. VARCHAR2(4000)) as string types in the field type check.
