## 0.5.3

### Patch Changes

- 154632d8753b: Add support for discovering additional service factories during startup.
- 37a20c7f14aa: Adds include and exclude configuration to feature discovery of backend packages
  Adds alpha modules to feature discovery
- cb7fc410ed99: The experimental backend feature discovery now only considers default exports from packages. It no longer filters packages to include based on the package role, except that `'cli'` packages are ignored. However, the `"backstage"` field is still required in `package.json`.
- 3fc64b9e2f8f: Extension points are now tracked via their ID rather than reference, in order to support package duplication.
- 3b30b179cb38: Add support for installing features as package imports, for example `backend.add(import('my-plugin'))`.
- b219d097b3f4: Backend startup will now fail if any circular service dependencies are detected.

## 0.5.0

### Minor Changes

- b9c57a4f857e: **BREAKING**: Renamed `configServiceFactory` to `rootConfigServiceFactory`.
- a6d7983f349c: **BREAKING**: Removed the `services` option from `createBackend`. Service factories are now `BackendFeature`s and should be installed with `backend.add(...)` instead. The following should be migrated:

  ```ts
  const backend = createBackend({ services: [myCustomServiceFactory] });
  ```

  To instead pass the service factory via `backend.add(...)`:

  ```ts
  const backend = createBackend();
  backend.add(customRootLoggerServiceFactory);
  ```

### Patch Changes

## 0.3.0

### Minor Changes

- 02b119ff93: **BREAKING**: The `httpRouterFactory` now accepts a `getPath` option rather than `indexPlugin`. To set up custom index path, configure the new `rootHttpRouterFactory` with a custom `indexPath` instead.

  Added an implementation for the new `rootHttpRouterServiceRef`.

### Patch Changes

- ecc6bfe4c9: Use new `ServiceFactoryOrFunction` type.
- b99c030f1b: Moved over implementation of the root HTTP service from `@backstage/backend-common`, and replaced the `middleware` option with a `configure` callback option.
- 170282ece6: Fixed a bug in the default token manager factory where it created multiple incompatible instances.
- 843a0a158c: Added service factory for the new core identity service.
- 150a7dd790: An error will now be thrown if attempting to override the plugin metadata service.
- 483e907eaf: Internal updates of `createServiceFactory` from `@backstage/backend-plugin-api`.
- 015a6dced6: The `createSpecializedBackend` function will now throw an error if duplicate service implementations are provided.
- e3fca10038: Tweaked the plugin logger to use `plugin` as the label for the plugin ID, rather than `pluginId`.
- ecbec4ec4c: Internal refactor to match new options pattern in the experimental backend system.
- 51b7a7ed07: Exported the default root HTTP router implementation as `DefaultRootHttpRouter`. It only implements the routing layer and needs to be exposed via an HTTP server similar to the built-in setup in the `rootHttpRouterFactory`.
- 0e63aab311: Moved over logging and configuration loading implementations from `@backstage/backend-common`. There is a now `WinstonLogger` which implements the `RootLoggerService` through Winston with accompanying utilities. For configuration the `loadBackendConfig` function has been moved over, but it now instead returns an object with a `config` property.
- 8e06f3cf00: Switched imports of `loggerToWinstonLogger` to `@backstage/backend-common`.
- 3b8fd4169b: Internal folder structure refactor.
