1. Improve user and role (user group) management: Admins can add different users and roles, and assign roles to users. Based on this, access authorization can be set in the project organization tree nodes (including HMI nodes) - this is achieved by setting one or more roles.

If a node itself does not have any authorization restrictions set, it will inherit the settings of its parent node.

When an HMI node in the organizational tree is limited by its own authorization or inherited authorization from its ancestors, during runtime, if the user wants to issue commands or perform other write operations on the monitoring UI displayed on the terminal, permission judgment will be triggered. If the current operator has not been verified, a user password verification dialog box will automatically pop up, and only authorized users can successfully write operations (issue commands).

2 Add an external HTTP API interface to the message flow node, and select an open api in the node to directly become an API for the backend system

3. Addition, improvement, and bug modification of some message flow nodes

4. Release version removes doc content to reduce volume

Users And Rules
HMI write operation (issue the command) authorization

用户与角色
HMI写操作(下达指令)授权) authorization

1 完善用户和角色（用户组）管理：管理员可以添加不同的用户和角色，并对用户进行角色分配。以此为基础，项目组织树节点中（含HMI节点），可以设定访问授权——这个通过设定一个或多个角色完成。

如果一个节点自身没有设置任何授权限定，则会继承父节点的设定。

当组织树中的一个HMI节点由自身授权或继承祖先的授权限定时，在运行过程中，用户如果要在终端展示的监控画面进行指令下达等写操作，则会触发权限判断。如果当前操作员没有进行验证，则会自动弹出用户密码验证对话框，并且只有有权限的用户才能写操作（下达指令）成功。

2 消息流节点新增外部HTTP Api接口，在节点中选择开放的接口，可以直接成为后端系统的api

3 一些消息流节点的新增、完善和bug修改

4 release版本去除doc内容，以减少体积

Transplanted and open sourced data synchronization between sub sites and centers, enabling IOT Tree to provide stronger support for enterprise level distributed applications. It can provide efficient and fast data aggregation function for on-site devices to connect to the center or cloud IoT platform.
