## 0.11.0

### Minor Changes

- abcdf44: **BREAKING**: The returned object from `createSpecializedApp` no longer contains a `createRoot()` method, and it instead now contains `apis` and `tree`.

  You can replace existing usage of `app.createRoot()` with the following:

  ```ts
  const root = tree.root.instance?.getData(coreExtensionData.reactElement);
  ```

- 8250ffe: **BREAKING**: Dropped support for the removed opaque `@backstage/ExtensionOverrides` and `@backstage/BackstagePlugin` types.

### Patch Changes

- 4d18b55: It's now possible to provide a middleware that wraps all extension factories by passing an `extensionFactoryMiddleware` to either `createApp()` or `createSpecializedApp()`.
- 4823831: Introduced a `createFrontendFeatureLoader()` function, as well as a `FrontendFeatureLoader` interface, to gather several frontend plugins, modules or feature loaders in a single exported entrypoint and load them, possibly asynchronously. This new feature, very similar to the `createBackendFeatureLoader()` already available on the backend, supersedes the previous `CreateAppFeatureLoader` type which has been deprecated.

## 0.9.0

### Minor Changes

- 7c80650: **BREAKING**: The `createSpecializedApp` function now creates a bare-bones app without any of the default app structure or APIs. To re-introduce this functionality if you need to use `createSpecializedApp` you can install the `app` plugin from `@backstage/plugin-app`.

  In addition, the `createApp` and `CreateAppFeatureLoader` exports are now deprecated as they are being moved to `@backstage/frontend-defaults`, which should be used instead.

- 62cce6c: Removed deprecated `icons` property passing to `createApp` and `createSpecializedApp`. Use `IconBundleBlueprint.make` to create extensions instead and include them in the app.

### Patch Changes

- fec8b57: Updated exports to use the new type parameters for extensions and extension blueprints.
- 2bb9517: Introduce the `@backstage/plugin-app` package to hold all of the built-in extensions for easy consumption and overriding.
- c816e2d: Added support for new `FrontendPlugin` and `FrontendModule` types.
- f3a2b91: Moved several implementations of built-in APIs from being hardcoded in the app to instead be provided as API extensions. This moves all API-related inputs from the `app` extension to the respective API extensions. For example, extensions created with `ThemeBlueprint` are now attached to the `themes` input of `api:app-theme` rather than the `app` extension.
- 0c70949: Reverse the order of API factory initialization in order to make sure that overrides from modules take priority
- 836127c: Updated dependency `@testing-library/react` to `^16.0.0`.
- 5446061: Internal refactor following removal of v1 extension support. The app implementation itself still supports v1 extensions at runtime.
- 948d431: Removing deprecated `namespace` parameter in favour of `pluginId` instead
- ddbeace: Added the ability to explicitly disable routes through the `bindRoutes` option by passing `false` as the route target. This also fixes a bug where route bindings in config were incorrectly prioritized above the ones in code in certain situations.
- 98850de: Added support for defining `replaces` in `createExtensionInput` which will allow extensions to redirect missing `attachTo` points to an input of the created extension.

  ```ts
  export const AppThemeApi = ApiBlueprint.makeWithOverrides({
    name: 'app-theme',
    inputs: {
      themes: createExtensionInput([ThemeBlueprint.dataRefs.theme], {
        // attachTo: { id: 'app', input: 'themes'} will be redirected to this input instead
        replaces: [{ id: 'app', input: 'themes' }],
      }),
    },
    factory: () {
      ...
    }
  });
  ```

- 4a66456: Added the `root` extension the replace the `app` extension as the root of the app.

## 0.6.0

### Minor Changes

- bdf4a8e: **BREAKING**: Removed the experimental `createExtensionTree` API.
- 86346c2: **BREAKING**: The `app.routes.bindings` app-config mapping has been simplified. You now only need to specify the plugin ID and route ID on both sides of the mapping.

  Old form:

  ```yaml
  app:
    routes:
      bindings:
        plugin.catalog.externalRoutes.viewTechDoc: plugin.techdocs.routes.docRoot
        plugin.catalog.externalRoutes.createComponent: plugin.catalog-import.routes.importPage
  ```

  New form:

  ```yaml
  app:
    routes:
      bindings:
        catalog.viewTechDoc: techdocs.docRoot
        catalog.createComponent: catalog-import.importPage
  ```

### Patch Changes

- 42ebf27: Added `IconsApi` implementation and the ability to configure icons through the `icons` option for `createApp` and `createSpecializedApp`. This is not a long-term solution as icons should be installable via extensions instead. This is just a stop-gap to make sure there is feature parity with the existing frontend system.
- bc621aa: Updates to use the new `RouteResolutionsApi`.
- e586f79: Wrap the root element with the analytics context to ensure it always exists for all extensions.
- 8fe56a8: Widen `@types/react` dependency range to include version 18.
- 8472188: Added or fixed the `repository` field in `package.json`.
- e0a4dd1: Improved the error message when data input/output shapes do not match
- fb9b5e7: The default `ComponentsApi` implementation now uses the `ComponentRef` ID as the component key, rather than the reference instance. This fixes a bug where duplicate installations of `@backstage/frontend-plugin-api` would break the app.
- 46b63de: Allow external route refs in the new system to have a `defaultTarget` pointing to a route that it'll resolve to by default if no explicit bindings were made by the adopter.

### Minor Changes

- d4149bf: **BREAKING**: Renamed the `app/router` extension to `app/root`.
- 074dfe3: Attaching extensions to an input that does not exist is now a warning rather than an error.

### Patch Changes

- 7d63b32: Accepts sub route refs on the new `createPlugin` routes map.
- 516fd3e: Updated README to reflect release status
- c97fa1c: Added `elements`, `wrappers`, and `router` inputs to `app/root`, that let you add things to the root of the React tree above the layout. You can use the `createAppRootElementExtension`, `createAppRootWrapperExtension`, and `createRouterExtension` extension creator, respectively, to conveniently create such extensions. These are all optional, and if you do not supply a router a default one will be used (`BrowserRouter` in regular runs, `MemoryRouter` in tests/CI).

### Minor Changes

- e539735: Updated core extension structure to make space for the sign-in page by adding `core.router`.
