+## [0.8.4]
+
+### Added
+
+- 登录令牌滑动续期:剩余有效期不足 12 小时的 GET/HEAD 鉴权请求经响应头换发同会话新令牌并延长会话行;登出、撤销会话与凭据变更对新旧令牌同时生效
+- 租户配置记录并透出 API Key 激活时间（keyActivatedAt），配合前端传播窗口提示；NotAuthenticated 错误附加「密钥无效或尚未生效」中文提示
+
+### Changed
+
+- 代理与网络类连接失败不再落 500「服务器内部错误」，改以 502 归类透出（code=UpstreamNetwork）并附中文提示；错误文案与服务端日志统一脱敏，不含代理凭据
+- API Key 激活落库增加乐观锁：测活期间租户被删除或凭据被并发修改时报错拒绝，不再覆盖较新数据
+- 代理主机字段拒绝携带用户凭据（@），用户名密码仅走专用字段
+- 升级 OCI Go SDK 至 v65.123.0
+
 ## [0.8.3]
