+### Dot notation indicates a component
+
+In Svelte 4, `<foo.bar>` would create an element with a tag name of `"foo.bar"`. In Svelte 5, `foo.bar` is treated as a component instead. This is particularly useful inside `each` blocks:
+
+```svelte
+{#each items as item}
+	<item.component {...item.props} />
+{/each}
+```
