 ### New Features
 
-- **Data contract delete methods**: Added `client.contracts.delete(guid)` to hard-delete all versions of a data contract and `client.contracts.delete_latest_version(guid)` to delete only the latest version and promote the previous one. Includes `extra_headers` support on `_call_api()` for per-request custom headers. Implemented across all 4 client variants (sync/async × v1/v9).
