get propertyPaneSettings() VS getPropertyPaneConfiguration()

Question

I want to create custom web part property in SPFX web part.
I am referring GitHub "sp-dev-fx-webparts-master" and other reference links...
in that reference, webpart.ts file contain "get propertyPaneSettings()" method and in my environment webpart.ts file by default contain "getPropertyPaneConfiguration()" method.

so, is there any difference between those method or both are same ?

reference link code.

protected get propertyPaneSettings(): IPropertyPaneSettings {  
    return {  
      pages: [  
        {  
          header: {  
            description: strings.PropertyPaneDescription  
          },  
          groups: [  
            {  
              groupName: strings.BasicGroupName,  
              groupFields: [  
                PropertyPaneTextField('description', {  
                  label: strings.DescriptionFieldLabel  
                })  
              ]  
            }  
          ]  
        }  
      ]  
    };  
  }  

My Web part Code.

protected getPropertyPaneConfiguration(): IPropertyPaneConfiguration {
    return {
      pages: [
        {
          header: {
            description: strings.PropertyPaneDescription
          },
          groups: [
            {
              groupName: strings.BasicGroupName,
              groupFields: [
                PropertyPaneTextField('description', {
                  label: strings.DescriptionFieldLabel
                })
              ]
            }
          ]
        }
      ]
    };
  }

Your reference code is referring to an older version of SPFx. IPropertyPaneSettings was used prior to RC0. But now, after RC0 and GA we are using IPropertyPaneConfiguration.

So, your webpart implementation is correct. So, both are the same "functionality" wise, but you should be using IPropertyPaneConfiguration in your code as IPropertyPaneSettings is now deprecated.
