-# 更新日志 (v0.6.0-beta.20210803)
-
-## 概览
-
-这是下一个正式版本 v0.6.0 的 beta 版本。**不推荐将此 beta 版本用作生产环境中**，因为它还没有被全面测试，也不足够稳定。另外，一些实用功能（例如 Git、Scrapy、消息通知）不计划在此 beta 版本发布，它们将以插件形式被整合进正式版本。
-
-## 升级优化
-
-作为一个重要版本发布，Crawlab v0.6（包括 beta 版本）由一些重大的功能升级组成，包括性能、稳定性、健壮性、易用性方面的大量优化。本次 beta 版本理论上会比老版本更加健壮，特别是任务执行、文件同步、节点通信上面。但是，我们还是推荐用户在 Crawlab 信版本上更全面的测试不同的爬虫任务。
-
-#### 后端
-
-- **文件同步**. 将文件同步从原先的 MongoDB GridFS 迁移到分布式文件系统 SeaweedFS，以提升文件同步和爬虫部署的稳定性和健壮性。
-- **节点通信**. 将节点通信从原先基于 Redis 套壳的 RPC 迁移到 gRPC。工作节点通过向主节点发起 gRPC 请求来与 MongoDB 数据库间接交互。
-- **任务队列**. 将任务队列从 Redis 列表迁移到 MongoDB 集合，以提高灵活性，例如优先级队列。
-- **日志**. 将日志储存迁移到 SeaweedFS，以解决 MongoDB 数据库中的性能问题。
-- **SDK 集成**. 将结果数据储存从原生 SDK 迁移到了任务处理器集中导入到数据库。
-- **任务相关**. 将任务相关逻辑抽象为了任务调度器、任务处理器以及任务执行器，以减少系统耦合度，提升可扩展性和可维护性。
-- **组件化**. 引入依赖注入框架，将模块、服务以及子系统进行模块化。
-
-#### 前端
-
-- **Vue 3**. 迁移到了最新的前端框架 Vue 3，以支持更高级的功能，例如组合式 API 和 TypeScript。
-- **UI 框架**. 从之前的 Vue-Element-Admin 迁移到了基于 Vue 3 的 UI 框架 Element-Plus，更多灵活性和功能性。
-- **高级文件编辑器**. 支持更高级的文件编辑器功能，包括拖砖操作、复制、移动、重命名、删除、文件编辑、代码高亮、导航标签等。
-- **可自定义表格**. 内置更多高级功能，包括自定义列、批量操作、搜索、过滤、排序等。
-- **导航标签**. 支持多导航标签查看不同的页面。
-- **批量创建**. 支持批量创建对象，包括爬虫、项目、定时任务等。
-- **详情导航**. 详情页里的侧边栏导航。
-- **更优化的仪表盘**. 主页仪表盘中更多的数据图表。
-
-## 待完成
-
-您可能已经知晓，这是一个 beta 版本，因此一些既有的实用功能（例如 Git 和 Scrapy 集成）还不支持。不过，由于代码中已经有一些基础功能，我们正努力将它们涵盖在 v0.6.0 的正式版本中。我们只会在它们被全面测试之后再加入到稳定版本中。
-
-- [ ] **插件框架**. 高级功能会以插件的形式集成到 Crawlab 中。
-- [ ] **Git 集成**. 将作为插件存在。
-- [ ] **Scrapy 集成**. 将作为插件存在。
-- [ ] **消息通知**. 将作为插件存在。
-- [ ] **关联任务**. 如果任务执行模式为 “所有节点” 或 “指定节点”，那么将会有主任务和子任务之分。
-- [ ] **Crontab 编辑器**. 可视化 Crontab 编辑的前端组件。
-- [ ] **结果去重**.
-- [ ] **环境变量**.
-- [ ] **国际化**. 支持中文.
-- [ ] **前端易用性优化**. 更多高级功能，例如表格形式保存。
-- [ ] **日志自动清理**.
-- [ ] **文档**.
-
-## 未来计划
-
-此次 beta 版本发布只是作为 Crawlab v0.6 核心功能测试的预览版本。我们诚信希望各位用户能下载安装并运行更多测试爬虫任务。在 beta 版中发现的主要问题解决后，以及插件框架和其他重要功能完成并通过测试之后，我们将发布正式版本。因此，在此之前，还可能会存在第二个更完善的 beta 版本。

-# Change Log (v0.6.0-beta.20210803)
-
-## Overview
-
-This is the beta release for the next major version v0.6.0. **It recommended NOT to use it in production** as it is not fully tested and thus not stable enough. Futhermore, more features including those not ready in the beta release (e.g. Git, Scrapy, Notification) are planned to be integrated into the live version, in the form of plugins.
-
-## Enhancement
-
-As a major release, v0.6 (including beta versions) is consisted of a number of large changes to enhance the performance, scalability, robustness and usability of Crawlab. This beta version is theoretically more robust than older versions mainly in task execution, files synchronization and node management, yet we still recommend users to thoroughly run tests with various samples.
-
-#### Backend
-
-- **File Synchronization**. Migrated file sync from MongoDB GridFS to SeaweedFS for better stability and robustness.
-- **Node Communication**. Migrated node communication from Redis-based RPC to gRPC. Worker nodes indirectly interact with MongoDB by making gRPC calls to the master node.
-- **Task Queue**. Migrated task queue from Redis list to MongoDB collection to allow more flexibility (e.g. priority queue).
-- **Logging**. Migrated logging storage system to SeaweedFS to resolve performance issue in MongoDB.
-- **SDK Integration**. Migrated results data ingestion from native SDK to task handler side.
-- **Task Related**. Abstracted task related logics into Task Scheduler, Task Handler and Task Runners to increase decoupling and improve scalability and maintainability.
-- **Compotenization**. Introduced DI (dependency injection) framework and componentized modules, services and sub-systems.
-
-#### Frontend
-
-- **Vue 3**. Migrated to latest version of frontend framework Vue 3 to support more advanced features such as composition API and TypeScript.
-- **UI Framework**. Built with Vue 3-based UI framework Element-Plus from Vue-Element-Admin, more flexibility and functionality.
-- **Advanced File Editor**. Support more advanced file editor features including drag-and-drop copying/moving files, renaming, deleting, file editing, code highlight, nav tabs, etc.
-- **Customizable Table**. Support more advanced built-in operations such as columns adjustment, batch operation, searching, filtering, sorting, etc.
-- **Nav Tabs**. Support multiple nav tabs for viewing different pages.
-- **Batch Creation**. Support batch creating objects including spiders, projects, schedules, etc.
-- **Detail Navigation**. Sidebar navigation in detail pages.
-- **Enhanced Dashboard**. More stats charts in home page dashboard.
-
-## TODOs
-
-As you may be aware that this is a beta release, some of the existing useful features such as Git and Scrapy integration may not be available. However, we are trying to include them in the official v0.6.0 release, as some of their core functionalities are already ready in the code base, and we will add to the stable version only if they are fully tested.
-
-- [ ] **Plugin Framework**. Advanced features will exist in the form of plugins, or pluggable modules.
-- [ ] **Git Integration**. To be included as a plugin.
-- [ ] **Scrapy Integration**. To be included as a plugin.
-- [ ] **Notifications**. To be included as a plugin.
-- [ ] **Associated Tasks**. There will be main tasks and their sub-tasks if task mode is "all nodes" or "selected nodes".
-- [ ] **Crontab Editor**. Frontend component that visualize the crontab editing.
-- [ ] **Results Deduplication**.
-- [ ] **Environment Variables**.
-- [ ] **Internationalization**. Support Chinese.
-- [ ] **Frontend Utility Enhancement**. Advanced features such as saved table customization. 
-- [ ] **Log Auto Cleanup**.
-- [ ] **Documentation**. 
-
-## What Next
-
-This beta release is only a preview and a test ground for the core functionalies in Crawlab v0.6. Therefore, we will invite you guys to download and run more tests. The official release is expected to be ready after major issues from the beta version are sorted and Plugin Framework and other key features are developed and fully tested. With that beared in mind, a second beta version before the main release will also be possible.

+# Change Log (v0.6.0)
+
+## Overview
+
+As a major release, v0.6.0 is consisted of a number of large changes to enhance the performance, scalability, robustness and usability of Crawlab. This beta version is theoretically more robust than older versions mainly in task execution, files synchronization and node management, yet we still recommend users to thoroughly run tests with various samples.
+
+## Enhancements
+
+#### Backend
+
+- **File Synchronization**. Migrated file sync from MongoDB GridFS to SeaweedFS for better stability and robustness.
+- **Node Communication**. Migrated node communication from Redis-based RPC to gRPC. Worker nodes indirectly interact with MongoDB by making gRPC calls to the master node.
+- **Task Queue**. Migrated task queue from Redis list to MongoDB collection to allow more flexibility (e.g. priority queue).
+- **Logging**. Migrated logging storage system to SeaweedFS to resolve performance issue in MongoDB.
+- **SDK Integration**. Migrated results data ingestion from native SDK to task handler side.
+- **Task Related**. Abstracted task related logics into Task Scheduler, Task Handler and Task Runners to increase decoupling and improve scalability and maintainability.
+- **Compotenization**. Introduced DI (dependency injection) framework and componentized modules, services and sub-systems.
+- **Plugin Framework**. **Crawlab Plugin Framework (CPF)** has been released. See more info [here](https://docs.crawlab.cn/en/guide/plugin/).
+- **Git Integration**. Git integration is implemented as a built-in feature.
+- **Scrapy Integration**. Scrapy integration is implemented as a plugin [spider-assistant](https://docs.crawlab.cn/en/guide/plugin/plugin-spider-assistant).
+- **Dependency Integration**. Dependency integration is implemented as a plugin [dependency](https://docs.crawlab.cn/en/guide/plugin/plugin-dependency).
+- **Notifications**. Notifications feature is implemented as a plugin [notification](https://docs.crawlab.cn/en/guide/plugin/plugin-notification).
+
+#### Frontend
+
+- **Vue 3**. Migrated to latest version of frontend framework Vue 3 to support more advanced features such as composition API and TypeScript.
+- **UI Framework**. Built with Vue 3-based UI framework Element-Plus from Vue-Element-Admin, more flexibility and functionality.
+- **Advanced File Editor**. Support more advanced file editor features including drag-and-drop copying/moving files, renaming, deleting, file editing, code highlight, nav tabs, etc.
+- **Customizable Table**. Support more advanced built-in operations such as columns adjustment, batch operation, searching, filtering, sorting, etc.
+- **Nav Tabs**. Support multiple nav tabs for viewing different pages.
+- **Batch Creation**. Support batch creating objects including spiders, projects, schedules, etc.
+- **Detail Navigation**. Sidebar navigation in detail pages.
+- **Enhanced Dashboard**. More stats charts in home page dashboard.
+
+#### Miscellaneous
+
+- **Documentation Site**. Upgraded [documentation site](https://docs.crawlab.cn/en).
+- **Official Plugins**. Allow users to install [official plugins](https://docs.crawlab.cn/en/guide/plugin/) on Crawlab web UI.
