Updates the supported Node.js engine versions to include Node.js 26.
This allows running the CLI on Node.js 26.0.0 and above while continuing to support active LTS versions.
In the context of AOT tests, component with defer blocks no longer throw on instanciation if the component is not overridden (with `overrideComponent`)
Prior to this change, all components with a `@defer` block would throw if `compileComponents` was not invoked.
In none-JIT apps, this change makes `compileComponents()` uneccesary.
Since angular@12181b9, zone stability
contributes to the PendingTasks. There is now a single source of truth for application stability
tracked in PendingTasks. This change makes protractor's whenStable compatible with zoneless.
The `Router` and `HttpClient` also contribute to stability using the
`PendingTasks` injectable. There will likely be more updates in the
future to have more features contribute to stableness in a zoneless
compatible way.
This update uses PendingTasks for stability by default when ZoneJS is not present or
can be enabled with an option when ZoneJS is present (but otherwise ignored with ZoneJS).

This registers AI runtime debugging tools during platform creation and unregisters them when the platform is destroyed. This roughly matches existing usage of global utils with respect to timing. It is limited to dev mode only because these tools are exclusively for debugging Angular's internals and not something production users would leverage.
This is a minimal implmentation which just focuses on registering parent shadow roots in `SharedStylesHost` correctly.
We don't currently reference count usage of host values, meaning that as soon as we call `removeHost`, all styles are removed from it, even if other components relied on them. Therefore there is no good way to know whether styles are still needed or not, leaving us with the choice of either leaking them longer than necessary or destroying them while another component still needs them. The compromise I'm using here is to delete styles when destroying a component under a shadow root (based on the assumption that only one component will exist per shadow root) and to leave styles when destroying a component in the main document (based on the assumption that dialogs being destroyed should not impact the main application).
Neither assumption is totally safe to make, but we're hoping this is a viable balance for the moment. In the future we should look into lifting these restrictions to better support those use cases while properly reference counting usage of hosts in `SharedStylesHost`.
I also added some small tests to confirm that SSR styles are not duplicated, as an earlier implementation accidentally duplicated them. This should ensure we don't repeat that mistake.
This shouldn't have been happening before, but now that we're going to start calling `addHost` during root component boostrap, we may call `addHost` on the same node multiple times and don't want to duplicate styles.
This commit updates provideClientHydration to automatically enable incremental hydration by default. It also introduces a new withNoIncrementalHydration feature for opting out, adds conflict safety checks, and includes a schematic migration.
Those APIs date back to pre-ivy times and are long deprecated.
BREAKING CHANGE: `ComponentFactoryResolver` and `ComponentFactory` are no longer available. Pass the component class directly to APIs that previously required a factory, such as `ViewContainerRef.createComponent` or use the standalone `createComponent` function.
This fixes a memory leak in `SharedStylesHost` where calling `removeHost` would leave any `<style>` or `<link>` tags associated with that host in the DOM. This is wasteful in general, and can create even more leaks if the same host is added and removed multiple times, causing styles to be consistently reappended but never removed.
BREAKING CHANGE: This removes styles when they appear to no longer be used by an associated `host`. However other DOM on the page may still be affected by those styles if not leveraging `ViewEncapsulation.Emulated` or if those styles are used by elements outside of Angular, potentially causing other DOM to appear unstyled.

The default change detection strategy is now OnPush.
BREAKING CHANGE: Component with undefined `changeDetection` property are now `OnPush` by default. Specify `changeDetection: ChangeDetectionStrategy.Eager` to keep the previous behavior.
Previously, Blob values were passed to `Uint8Array` this resulted in silently producing an empty array (length = 0) without throwing an error, leading to empty cached data

This commit updates the minimum supported Node.js versions. Node.js v20 support is dropped, and the minimum version for Node.js v22 is bumped to v22.22.0, and for v24 it is bumped to v24.13.1.
BREAKING CHANGE: Node.js v20 is no longer supported. The minimum supported Node.js versions are now v22.22.0 and v24.13.1.
This adds a new method to the TestBed to retrieve the most recently created component fixture. This is useful for cases where the fixture is created in a beforeEach and needs to be accessed in a test.
If multiple fixtures have been created, this method will throw an error to prevent depending on fixture creation order.
Error message links now point to the archived documentation site (v*.angular.dev)
so that referenced content matches the framework version in use.

This commit adds a utility method to debug why the application has not stabilized after
a set period of time (9 seconds, or `hydrationTimeout-1`).

The` platformIsServer` flag is no longer referenced by the renderer and is effectively unused.
Removing it simplifies the implementation and avoids carrying redundant state.
This change replaces all remaining occurrences of `typeof ngDevMode !== undefined`
with the correct `typeof ngDevMode !== 'undefined'` form. This aligns the codebase
with JavaScript typeof semantics and maintains consistency with other Angular code.
This is necessary to use SSR safely with `createApplication` and avoid constraining users to `bootstrapApplication`. It is one more step towards feature parity between `createApplication` and `bootstrapApplication`.
Annotate the `new Version(...)` call with `/* @__PURE__ */` to signal to optimizers that the constructor is side-effect free.
Without this hint, bundlers such as Terser or ESBuild may conservatively retain the `VERSION` instantiation even when unused. With the annotation, the constant can be tree-shaken away in production builds if not referenced, reducing bundle size.
The `requireSynchronousElementRemoval` property was not being passed in all the locations it was needed. This was preventing leave animation timing from behaving properly in some cases.

Since those are top level APIs, `ngDevMode` might not be available at runtime if they're invoked before the variable is set.
