v1.2.2

[1.2.2] - 2026-09-25

Added

• datacontract api: --contract-variables and --allow-local-files options, as alternatives to their environment variables
• datacontract import odata creates a datacontract from OData 4 metadata at a URL or from a local file (#1649 @jahlen)
• datacontract export writes SQL Server VECTOR(n) and VECTOR(n, float16) vector types
• datacontract test checks constraints and quality rules of nested properties on servers read through DuckDB (#1278)

Changed

• datacontract lint and datacontract test: a quality rule the CLI cannot run is reported as a warning instead of being silently dropped
• The bundled Data Contract Editor (datacontract edit) is updated to 0.1.14
• ${VAR} references are accepted in fields with a fixed set of values (quality.type, quality.metric, quality.dimension, logicalType, servers[].type); datacontract test fails when one resolves into anything else
• datacontract test reports nested checks it cannot run and unsupported type checks on parquet files as warnings (#1278)

Security

• datacontract api:
  • a posted data contract resolves ${VAR} only from the variables allow-listed with --contract-variables
  • a ${X:-local} server type no longer slips past the checks for local files and environment-held credentials
• datacontract test: a SQL quality rule on a mysql server can no longer reach the MySQL server or its credentials; rules on mysql and iceberg servers are read as DuckDB SQL

Fixed

• Loading a DCS contract dropped quality rule arguments, so invalidValues and missingValues rules lost their configuration
• datacontract test --dry-run: a check that could not be planned no longer reports the run as skipped
• Non-ASCII characters in data contract and import source files are now decoded as UTF-8, fixing garbling on Windows (#1650 @ymurong)
• datacontract test: SQL quality rule placeholders are quoted when the name needs it (e.g. a column with a space), and a query that does not parse reports the parse error (#1653)
• datacontract import spark preserves varchar(...) and char(...) types nested inside struct, array and map columns instead of widening them to string (#1634 @IchEssBlumen)
• datacontract import jsonschema keeps the type of nullable anyOf/oneOf properties and warns about union types (#1278)
• datacontract export sodacl warns about the nested properties it leaves out (#1278)
