## release note

- for convenient,I tag the version of the project (mainly on the client ) with data time
- the time(version) was create by powershell :

  - ```powershell
    Get-Date -Format "yyyy-MM-dd@HH:mm:ss"
    ```
  
  - copy to clipbord automatically
  
    ```bash
    Get-Date -Format "yyyy-MM-dd@HH:mm:ss"|scb
    ```
  
    
  
  

### versions with time
