v0.12.1

[0.12.1] - 2026-04-21

This release introduces several changes to improve the usability of datacontract-cli for AI Agents.

• Breaking: Several changes in the CLI syntax (#1157):

Fix in v0.12.1: re-added --schema as alias for the new --json-schema (will be removed in v0.13.0)

Command	Old option	New option
lint, test, ci, publish, catalog	--schema <PATH> (still works until v0.13.0)	--json-schema <PATH>
export, import	--format <FORMAT> <OPTIONS>	<FORMAT> <OPTIONS> (drop --format)
Export options:
export --format dbt	--format dbt	dbt-models (format renamed)
export --format great-expectations	--sql-server-type <TYPE>	--dialect <TYPE>
export --format rdf	--rdf-base <URI>	--base <URI>
export --format sql	--sql-server-type <TYPE>	--dialect <TYPE>
export --format sql-query	--sql-server-type <TYPE>	--dialect <TYPE>
Import options:
import --format bigquery	--bigquery-[project|dataset|table] <NAME>	--[project|dataset|table] <NAME>
import --format dbt	--dbt-model <NAME>	--model <NAME>
import --format glue	--source <NAME>, --glue-table <NAME>	--database <NAME>, --table <NAME>
import --format iceberg	--iceberg-table <NAME>	--table <NAME>
import --format unity	--unity-table-full-name <NAME>	--table <NAME>
import --format spark	--source <NAMES>	--tables <NAMES>
import	--template	dropped (was a no-op)

The --schema option (referring to the ODCS JSON schema) was renamed to --json-schema to avoid confusion with --schema-name, which refers to the schema within the data contract to test for.

• Error messages for uncaught exceptions are shortened now. Pass --debug (or set DATACONTRACT_CLI_DEBUG=1) to see the full traceback. (#1175)
• Add example calls to --help outputs (#1176)
• Add explicit errors when required env vars for soda connections are missing (#1177)
• Validate some of the CLI options against their allowed values instead of accepting any string (#1178)
