+## [3.0.0](https://github.com/trussworks/react-uswds/compare/2.9.0...3.0.0) (2022-04-25)
+
+
+### ⚠ BREAKING CHANGES
+
+* Previous deprecated features and props have been removed. Please see the following guidance for affected components:
+  * Accordion: Default heading level has been removed. Consumers must now specify via the `headingLevel` prop.
+  * Alert: Default heading level has been removed. Consumers must now specify via the `headingLevel` prop.
+  * Button: 
+    * `accent` has been removed. Use `accentStyle` instead.
+    * `big`, `small`, and `size="small"` have been removed. Use `size="big"` or do not define the `size` prop for default sizing.
+  * CollectionHeading: Default heading level has been removed. Consumers must now specify via the `headingLevel` prop.
+  * Footer/Address: `big`, `medium`, and `slim` props have been removed. Use the `size` prop instead.
+  * Footer/Footer: `big`, `medium`, and `slim` props have been removed. Use the `size` prop instead.
+  * Footer/FooterNav: `big`, `medium`, and `small` props have been removed. Use the `size` prop instead.
+  * Footer/Logo: `big`, `medium`, and `small` props have been removed. Use the `size` prop instead.
+  * Search: `big`, and `small` props have been removed. Use the `size` prop instead.
+  * Fieldset: `legendSrOnly` has been removed. Use `legendStyle="srOnly"` instead.
+  * TextInput: `error`, and `success` props have been removed. Use the `validationStatus` prop instead.
+  * header/NavList: `primary`, `secondary`, `subnav`, `megamenu`, and `footerSecondary` props have been removed. Use the `type` prop instead.
+  * StepIndicator: Default heading level has been removed. Consumers must now specify via the `headingLevel` prop.
+* SummaryBox now exposes sub-components (SummaryBoxHeading and SummaryBoxContent) for a more compositional API. Consumers will need to update their implementation to match.
+* In order to accommodate IconList as a named component, Icons themselves needed to be refactored. All use of ReactUSWDS icons now follows the following syntax: <Icon.{IconName} /> instead of <Icon{IconName />. Furthermore, icons are no longer imported individually. Instead, Icon (the class) is imported to then use any <Icon.{IconName}> consumers require.
