BootStrap 5.0 beta 1 Carousel Slide not working

I'm having trouble making the carousel actually slide. It would just swap to next item without any "slide" transition. I've even went through the BS 5 doc and it doesn't do the slide transition either. Has it been removed?

HTML:

<div id="carouselExampleSlidesOnly" class="carousel slide" data-bs-slide ="true" data-bs-ride="carousel" data-bs-interval="1000" data-bs-pause="hover"> 
  <div class="carousel-inner">
    <div class="carousel-item active " style = "background-color:red">
      <img src="..." class="d-block w-100" alt="...">
    </div>
    <div class="carousel-item" style = "background-color:blue">
      <img src="..." class="d-block w-100" alt="...">
    </div>
    <div class="carousel-item" style = "background-color:yellow">
      <img src="..." class="d-block w-100" alt="...">
    </div>
  </div>
</div>

CSS:

.carousel-item {
    height: 500px;
}
