Angular-maps-template

Hola, me gustaría saber porque los templates que se muestran en angular-google-maps son tan diferentes?

Este es el que se usa en el video de la clase

<agm-map [latitude]="lat" [longitude]="lng">
  <agm-marker [latitude]="lat" [longitude]="lng"></agm-marker>
</agm-map>

Este es el que se muestra en Playing with Angular Google Maps (AGM)

<sebm-google-map 
      [latitude]="lat"
      [longitude]="lng"
      [zoom]="zoom"
      [disableDefaultUI]="false"
      [zoomControl]="false"
      (mapClick)="mapClicked($event)">
    
      <sebm-google-map-marker 
          *ngFor="let m of markers; let i = index"
          (markerClick)="clickedMarker(m.label, i)"
          [latitude]="m.lat"
          [longitude]="m.lng"
          [label]="m.label"
          [markerDraggable]="m.draggable"
          (dragEnd)="markerDragEnd(m, $event)">
          
        <sebm-google-map-info-window>
          <strong>InfoWindow content</strong>
        </sebm-google-map-info-window>
        
      </sebm-google-map-marker>
      
      <sebm-google-map-circle [latitude]="lat + 0.3" [longitude]="lng" 
          [radius]="5000"
          [fillColor]="'red'"
          [circleDraggable]="true"
          [editable]="true">
      </sebm-google-map-circle>

    </sebm-google-map>
