+## [2.8.3] - 2026-11-06
+
+### Added
+
+- **Model-based web search**: `bl search web` adds a model search mode and now uses it as the default implementation.
+- **Web search in chat**: `bl text chat` supports built-in web search via the `enable_search` parameter.
+
+### Changed
+
+- **Profile credentials**: Profiles can now declare credentials per search mode (`model` / `mcp`), and the CLI picks the matching profile credential when switching search modes.
+

+## [2.8.3] - 2026-11-06
+
+### 新增
+
+- **模型联网搜索**：`bl search web` 新增模型搜索模式（`--mode model`），并改为默认实现。
+- **对话内置联网搜索**：`bl text chat` 新增 `enable_search` 参数，支持内置联网搜索。
+
+### 变更
+
+- **Profile 凭证**：Profile 可按搜索模式（`model` / `mcp`）声明凭证，切换搜索模式时自动选择对应 Profile 凭证。
