 Vue 3 united the `slot` and `scoped-slot` syntax under a single syntax, `v-slot`, which you can read about in the [the docs](https://v3.vuejs.org/guide/migration/slots-unification.html#overview). Since `slot` and `scoped-slot` are now merged, the `scopedSlots` mounting option is now deprecated - just use the `slots` mounting option for everything.
 
+### `slots`‘s scope is now exposed as `params`
+
+When using string templates for slot content, if not explicitly defined using a wrapping `<template #slot-name="scopeVar">` tag, slot scope becomes available as a `params` object when the slot is evaluated.

 ### `findAll().at()` removed
 
 `findAll()` now returns an array of DOMWrappers.

Subject: [PATCH 2/2] docs(guide): note about slot scope when not wrapped in
 template tag

https://github.com/vuejs/test-utils/blob/39d86ad5abe71bac8d76c5b82f11f30225cf8673/src/utils/compileSlots.ts#L10

The only example provided used an explicit #default="params", but it doesn't mention that if you don't explicitly wrap it, the slot scope becomes also available as params. In VTU1, they were exposed as props, so i think it's better to be explicit about it.

 ## Conclusion
 
 - Use the `slots` mounting option to test components using `<slot>` are rendering content correctly.
