+## [1.18.0] - 2026-08-27
+
+### Added
+
+- **Automatic Profile API Key fallback** — unsupported commands use the API Key and endpoint from `default` without requiring a Profile switch; explicit credentials still take priority.
+- **Independent speech defaults** — Profiles support separate default models for TTS and ASR.
+- **Wan3.0 file-to-video** — `bl video generate --file` accepts local files or URLs and validates incompatible inputs.
+
+### Changed
+
+- **Wan3.0 is now the default video model** — regular API Key text, image, and reference video tasks default to `wan3.0-video`, with first/last-frame and reference-audio support. Token Plan defaults remain unchanged.
+- **Expanded Token Plan preset** — login adds speech defaults and missing capabilities while preserving existing user configuration.
+- **Improved speech and Skill installation experience** — streaming synthesis defaults to PCM; installation docs add a Node 18-compatible fallback and clarify the Node.js and Git prerequisites.
+

+## [1.18.0] - 2026-08-27
+
+### 新增
+
+- **Profile API Key 自动回退** —— 当前 Profile 不支持某条命令时，自动使用 `default` 中的 API Key 和接入地址，无需手动切换 Profile；显式凭证仍然优先。
+- **语音合成与识别支持独立默认模型** —— Profile 支持分别配置 TTS 和 ASR 默认模型。
+- **Wan3.0 文件生视频** —— `bl video generate --file` 支持本地文件或 URL，并校验互斥输入。
+
+### 变更
+
+- **视频默认模型升级至 Wan3.0** —— 普通 API Key 的文生、图生和参考生视频默认使用 `wan3.0-video`，并支持首尾帧与参考音频；Token Plan 默认模型保持不变。
+- **扩展 Token Plan 预设** —— 登录后自动补充语音默认模型和缺失能力，同时保留用户已有配置。
+- **优化语音与 Skill 安装体验** —— 流式语音合成默认输出 PCM；Skill 安装文档补充兼容 Node 18 的降级方式及 Node.js、Git 前置条件。
