### Breaking changes

- Removed `groups` prop on `Select`. Pass groups to the `options` prop instead. ([#1831](https://github.com/Shopify/polaris-react/pull/1831))
- Removed `Autocomplete.ComboBox.TextField` and `Autocomplete.ComboBox.OptionList`. You should use the `Autocomplete.TextField` and `OptionList` components instead. ([#1830](https://github.com/Shopify/polaris-react/pull/1830))
- Removed `secondaryFooterAction` prop on `Card`. Pass an array of secondary actions to the `secondaryFooterActions` prop instead. ([#1831](https://github.com/Shopify/polaris-react/pull/1831))
- Removed `iconBody` prop on `Navigation.Item`. Pass a string to the `icon` prop instead. ([#1831](https://github.com/Shopify/polaris-react/pull/1831))
- Removed the `WithContext` component, as it was an undocumented part of the public API meant for internal use only ([#1641](https://github.com/Shopify/polaris-react/pull/1641))
- Removed the `WithRef` component, as it was an undocumented part of the public API meant for internal use only ([#1610](https://github.com/Shopify/polaris-react/pull/1610))
- Removed support for passing a string into `<Icon source>` to load a bundled icon. You must load the required icon directly from `@shopify/polaris-icons` instead. ([#1604](https://github.com/Shopify/polaris-react/pull/1604))

- Removed `Navigation.UserMenu`. Use `TopBar.UserMenu` instead. ([#1599](https://github.com/Shopify/polaris-react/pull/1599))

Applications consuming Polaris using TypeScript must enable [`esModuleInterop`](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-7.html#support-for-import-d-from-cjs-from-commonjs-modules-with---esmoduleinterop) in `tsconfig.json`. ([#1523](https://github.com/Shopify/polaris-react/pull/1523))
- Removed `LinkLikeComponent` type export. Use `AppProviderProps['linkComponent']` instead. ([#1864](https://github.com/Shopify/polaris-react/pull/1864))
