+## [0.7.2] - 2026-03-28
+
+### Changed
+
+- Refactor watch mode: extract `_handle_key`, `_draw_header`, `_draw_content` helpers from 271-line nested `_run` function.
+- Replace `reconnect_state` dict with `_ReconnectState` dataclass for type-safe reconnection state.
+- Replace all Unicode symbols with ASCII equivalents throughout TUI and CLI output.
+
+### Added
+
+- Tests for `_dump_yaml`, `_write_multi_doc_yaml`, `_find_unknown_flows`, `_print_unknown_warnings`, `_print_summary`, `_trunc`, `_print_report`, `_ReconnectState`, and `_handle_key` (39 new tests, 120 total).
+- Error-path tests for `_parse_duration` and `_read_flows`.
+
+## [0.7.1] - 2026-03-28
+
+### Fixed
+
+- Use module logger (`LOG.debug`) instead of root `logging.debug` in `_detect_hubble_cmd`.
+- Replace `assert` guards in reader threads with early-return checks (assertions are stripped under `python -O`).
+- Guard `cursor_flow_idx` when `ordered_keys` is empty in watch select mode.
+- Close capture file handle on early exit paths to prevent resource leak.
+- Add missing `py.typed` marker file (referenced in CHANGELOG since v0.4.0 but never created).
+- Add `types-PyYAML` to dev dependencies so local `mypy` works without manual installs.
+- Add `.mypy_cache/`, `.pytest_cache/`, `.ruff_cache/` to `.gitignore`.
