+# 0.4.10 (2020-04-21)
+### 功能 / 优化
+- **优化日志管理**. 集中化管理日志，储存在 MongoDB，减少对 PubSub 的依赖，允许日志异常检测.
+- **自动安装依赖**. 允许从 `requirements.txt` 和 `package.json` 自动安装依赖.
+- **API Token**. 允许用户生成 API Token，并利用它们来集成到自己的系统中.
+- **Web Hook**. 当任务开始或结束时，触发 Web Hook http 请求到预定义好的 URL.
+- **自动生成结果集**. 如果没有设置，自动设置结果集为 `results_<spider_name>`.
+- **优化项目列表**. 项目列表中不展示 "No Project".
+- **升级 Node.js**. 将 Node.js 版本从 v8.12 升级到 v10.19.
+- **定时任务增加运行按钮**. 允许用户在定时任务界面手动运行爬虫任务.

+# 0.4.10 (2020-04-21)
+### Features / Enhancement
+- **Enhanced Log Management**. Centralizing log storage in MongoDB, reduced the dependency of PubSub, allowing log error detection.
+- **API Token**. Allow users to generate API tokens and use them to integrate into their own systems.
+- **Web Hook**. Trigger a Web Hook http request to pre-defined URL when a task starts or finishes.
+- **Auto Install Dependencies**. Allow installing dependencies automatically from `requirements.txt` or `package.json`.
+- **Auto Results Collection**. Set results collection to `results_<spider_name>` if it is not set.
+- **Optimized Project List**. Not display "No Project" item in the project list.
+- **Upgrade Node.js**. Upgrade Node.js version from v8.12 to v10.19.
+- **Add Run Button in Schedule Page**. Allow users to manually run task in Schedule Page.
+
+### Bug Fixes
+- **Cannot register**. [#670](https://github.com/crawlab-team/crawlab/issues/670)
+- **Spider schedule tab cron expression shows second**. [#678](https://github.com/crawlab-team/crawlab/issues/678)
+- **Missing daily stats in spider**. [#684](https://github.com/crawlab-team/crawlab/issues/684)

 添加节点的方式非常简单，您只需要在目标机器上运行一个 Crawlab 服务就可以了。
 
-#### Docker 部署
-如果您是用 Docker 启动 Crawlab，可以在目标机器上运行一个新的 \`worker\` 容器，或者在 \`docker-compose.yml\` 中添加 \`worker\` 服务。
-
-\`\`\`bash
-docker run -d --restart always --name crawlab_worker \\
-  -e CRAWLAB_SERVER_MASTER=N \\

-  -e CRAWLAB_REDIS_ADDRESS=xxx.xxx.xxx.xxx \\ # 保证连接的是同一个 Redis
-  tikazyq/crawlab:latest

-
-#### 直接部署
-如果您是用直接部署，只需要在目标机器上启动一个后端服务，请参考 [直接部署文档](https://docs.crawlab.cn/Installation/Direct.html)。
