+## 0.2.1（2026-08-31）
+
+### 体验改进
+
+- **进度中心**：分析和同步任务统一在顶栏查看；已完成、失败或取消的单个任务可独立清除，批量分析提示与实际入口保持一致。
+- **并行分析**：支持在设置中配置同时分析数量（1–8，默认 2），多个知识分析任务可并行执行。
+
+### 修复
+
+- 分析完成后自动刷新详情页并展示最新知识笔记；加强取消、重复排队和超时场景下的任务状态一致性。
+- Release 发布 Action 升级至 Node.js 24 运行时版本，消除 Node.js 20 弃用警告。

+## 0.2.1（2026-08-31）
+
+### 分析任务
+
+- `DistillerConfig.max_concurrent_analyses` 支持 1–8 的动态并发上限，默认 2；分析任务共享读锁，同步任务继续持有写锁。
+- 每个运行中的分析条目使用独立 Sidecar；RPC 响应按请求 ID 分发，取消和超时只影响对应条目。
+- 在事务内拒绝同批次重复会话及已排队/运行会话；取消后正确完成条目计数并允许重新分析。
+
+### 桌面与发布
+
+- 顶栏进度中心支持逐项清除终态任务，补齐等待、单项处理和并行处理状态及无障碍语义。
+- 分析完成后按最新 `cardId` 刷新详情并替换 URL；启动失败不再留下错误的分析中状态。
+- `softprops/action-gh-release` 升级到 `v3.0.3`，使用 Node.js 24 运行时。
