 格式遵循 [Keep a Changelog](https://keepachangelog.com/zh-CN/1.1.0/)，版本号遵循语义化版本。
 
+## [0.2.0] - 2026-07-12
+
+### Added
+
+- AI 网关页「模型黑名单」管理：模型列表按厂商手风琴分组展示，可一键拉黑（全渠道剔除）、移除后重新同步渠道恢复
+- AI 密钥模型白名单编辑：创建 / 编辑密钥时可限定放行的模型列表（空 = 不限）
+- 渠道 / 密钥表单「现有分组」chips：点击即填入分组输入框
+
+### Changed
+
+- 租户删除确认弹窗分段排版（标题 / 面板清理范围 / 云端提示），列表与详情页文案一致
+
 ## [0.1.0] - 2026-07-10
 
 ### Added
