at-rules. The change should be more theoretically breaking than practically
breaking in practice.

+## v8.0.0 - 2025-10-17
+
+### Breaking change
+
+Subsidiary at-rules are now reported at the root level, scoped to their parent at-rule through a `for` property.
+
+### How to upgrade
+
+Unless you're processing at-rules and only expecting unscoped ones, upgrade from version 7 should not require any code update. If you need to list only unscoped at-rules, filter out those that have a `for` property.

 Additional keys may be set depending on the type of the CSS feature. For example:
 
 - At-rules have a `descriptors` key that contains the list of descriptors defined for the given at-rule. That list may not be exhaustive. For example, it does not contain descriptors that are only implicitly defined in specs, such as families of properties that some at-rules (e.g, `@position-try`) accept as descriptors.
+- At-rule that are scoped to another at-rules have a `for` key that contains the list of scoping at-rules.
 - Functions and types that are scoped to a property or other feature have a `for` key that contains the list of scoping features for that feature. A scoping feature may be a property, a function or a type. When the scoping feature is a type, its name in the `for` key is enclosed between `<` and `>`.
 - Properties have a `styleDeclaration` key that contains the list of IDL attribute names that the property generates. A number of other keys may be set to describe the property's initial value, animation type and other parameters.
