+## [0.1.9] - 2026-03-06
+
+### 🐞 错误修复
+- 修复diff截断时的字符边界问题
+
+## [0.1.7] - 2026-02-14
+
+### 🐞 错误修复
+- 修复 `changelog` 命令默认覆盖文件的问题，现改为智能追加新版本条目到头部之后
+
+### 🔧 其他变更
+- 清理 `formatter.rs` 中未使用的函数（`format_commit_date`、`format_changelog_date`、`format_tag_name`、`truncate`、`format_markdown_list`、`format_changelog_section`、`format_git_config_key`）
+- 清理 `validators.rs` 中未使用的函数（`validate_ssh_key`）
+- 移除 `changelog` 命令的 `--prepend` 参数（默认行为已改为追加）
