 # Router Component Store changelog
 
+## 15.0.0-rc.0 (2024-09-03)
+
+### Features
+
+- Remove optional type parameter from `RouterStore#selectRouteData`
+- Replace `MinimalRouteData` with `StrictRouteData`
+- Change `RouterStore#routeData$` and `MinimalActivatedRouteSnapshot#data` types from `Data` to `StrictRouteData`
+- Use strict and immutable route parameters
+- Use strict and immutable query parameters
+
+**BREAKING CHANGES**
+
+The type parameter is removed from `RouterStore#selectRouteData` for stricter typing and to enforce coercion.

+```typescript
+// heroes.component.ts
+// (...)
+import { RouterStore } from '@ngworker/router-component-store';
+@Component({
+  // (...)
+})
+export class HeroesComponent {
+  #routerStore = inject(RouterStore);
+  limit$ = this.#routerStore.selectRouteData<number>('limit');
+}
+```
+
+AFTER:
+
+```typescript
+// heroes.component.ts
+// (...)
+import { RouterStore } from '@ngworker/router-component-store';
+@Component({
+  // (...)
+})
+export class HeroesComponent {
+  #routerStore = inject(RouterStore);
+  limit$ = this.#routerStore.selectRouteData('limit').pipe(x => Number(x));
+```
+
+The `RouterStore#routeData$` selector emits `StrictRouteData` instead of `Data`.
+
+BEFORE:
+
+```typescript
+// heroes.component.ts
+// (...)
+import { RouterStore } from '@ngworker/router-component-store';
+@Component({
+  // (...)
+})
+export class HeroesComponent {
+  #routerStore = inject(RouterStore);
+  limit$: Observable<number> = this.#routerStore.routeData$.pipe(
+    map((routeData) => routeData['limit'])
+  );
+}
+```
+
+AFTER:
+
+```typescript
+// heroes.component.ts
+// (...)
+import { RouterStore } from '@ngworker/router-component-store';
+@Component({
+  // (...)
+})
+export class HeroesComponent {
+  #routerStore = inject(RouterStore);
+  limit$: Observable<number> = this.#routerStore.routeData$.pipe(
+    map(routeData => routeData['limit']),
+    map(x => Number(x))
+  );
+```
+
+`RouterStore#routeParams$` and `MinimalActivatedRouteSnapshot#params` use `StrictRouteData` instead of `Params`. Members are read-only and of type `string | undefined` instead of `any`.
+
+TypeScript will fail to compile application code that has assumed a route type parameter type other than `string | undefined`.
+
+BEFORE:
+
+```typescript
+// heroes.component.ts
+// (...)
+import { RouterStore } from '@ngworker/router-component-store';
+
+@Component({
+  // (...)
+})
+export class DashboardComponent {
+  #routerStore = inject(RouterStore);
+
+  limit$: Observable<number> = this.#routerStore.routeParams$.pipe(
+    map((params) => params['limit'])
+  );
+}
+```
+
+AFTER:
+
+```typescript
+// heroes.component.ts
+// (...)
+import { RouterStore } from '@ngworker/router-component-store';
+
+@Component({
+  // (...)
+})
+export class DashboardComponent {
+  #routerStore = inject(RouterStore);
+
+  limit$: Observable<number> = this.#routerStore.routeParams$.pipe(
+    map((params) => Number(params['limit'] ?? 10))
+  );
+}
+```
+
+`StrictRouteData` members are now read-only.
+
+TypeScript will fail to compile application code that mutates route data data structures.

+    map((data) => Number(data['limit']))
+  );
+}
+```
+
+`RouterStore#queryParams$` and `MinimalActivatedRouteSnapshot#queryParams` use `StrictRouteParams` instead of `Params`. Members are read-only and of type `string | undefined` instead of `any`.
+
+TypeScript will fail to compile application code that has assumed a query parameter type other than `string | undefined`.
