+# Changelog
+
+## v0.2.0 — Dead Code Cleanup
+
+Internal cleanup with no user-facing behavior changes. Tokenization output
+is identical.
+
+### Breaking changes
+
+- **`concatenate_nodes()` signature simplified.** Removed two dead parameters:
+  - `force_oov: bool` — was always ignored (`let _ = force_oov`); the
+    concatenated node is unconditionally `is_oov: true`.
+  - `_normalized_override: Option<&str>` — was never read.
+
+### Internal
+
+- **Deduplicated `resolved_form()`.** The `tokenizer.rs` copy (returning
+  `String` via `.clone()`) removed in favor of the canonical
+  `path_rewrite::resolved_form()` (returning `&str`). The single call site
+  that needs ownership calls `.to_string()`.
+
+### Dependencies
+
+- kiri-kotoba bumped to 0.2.0.
+
+## v0.1.0 — Initial Release
+
+Standalone Rust Japanese morphological tokenizer: Viterbi lattice solver,
+path rewriting (katakana OOV join, numeric join), split modes A/B/C, CLI.
