+## [Unreleased - proposed 1.0.0?]
+
+### Added
+- `output_dir` parameter to `write_search_results_to_file`, defaulting to `./tmp`
+- `fetch_file` now defaults `output_dir` to `./tmp` when not supplied
+
+### Removed
+- **BREAKING**: `default_storage_dir` constructor parameter removed from `TINDClient`; pass `output_dir` directly to `fetch_file` and `write_search_results_to_file` instead
+
 ## [0.2.2]
