Adds the `isFieldTree` utility that allows users to assert whether a value is a field tree. This is something that has come up on Material recently and will be useful for users as well.
Fixes#69984.
`@HostListener` is not limited to methods — it is equally valid on a property
holding a function, which is the idiomatic way to keep `this` bound:
@HostListener('window:beforeunload', ['$event'])
private onUnload = (event: BeforeUnloadEvent) => {...};
Every existing host-listener compliance case declares the handler as a method,
so the property form was uncovered. This adds a case exercising both a public
and a private function-valued property, one of them with a global (`window:`)
event target, and locks in the emitted chained `ɵɵlistener` calls plus
`ɵɵresolveWindow`.
Verified against all four compliance modes (full, partial/linked,
declaration-only); GOLDEN_PARTIAL.js regenerated via the golden update rule.
Updates the strictTemplates documentation in Angular compiler options to note that the default is true, replacing the reference to the obsolete ng new --strict flag.
Conditionally update the browser DevTools tab name to "Angular & Wiz" if the user is identified as a Google employee via internal corp network detection.
Include the XSRF interceptor in the root token factory so the automatically provided HttpClient retains the documented default protection without requiring provideHttpClient().
Normalize value-specific HttpHeaders deletions before filtering. The string overload previously used String#indexOf and removed shorter values contained within the requested deletion value, potentially widening outgoing request metadata.
Preserve delete-all behavior only when no value is supplied, and cover string, array, and empty-string deletion.
Prevent lazy HttpHeaders and HttpParams clones from reusing value arrays owned by a materialized source. Append and value-specific delete operations previously mutated those shared arrays, violating the immutable API contract and allowing request metadata to bleed into later requests.
Share value arrays until an update mutates a specific header or parameter, then copy only that array. Cover the affected append and delete paths with regression tests that materialize the source first.
Rename Timing API to Performance Track to better reflect the purpose of the actual feature;
Migrate the settings data object to match the new name and drop some redundant keys.
Make runtime URL sanitizer selection namespace-aware so SVG and MathML host bindings match the security schema.
Cover SVG href/xlink:href and MathML href host binding cases, including dynamic hostElement resolution.
PR Close#69558
Host binding sanitization previously used the declaring directive or component selector to choose a compile-time security context. The same host binding can execute on a different concrete element through hostDirectives, inherited host bindings, dynamic directives, or createComponent hostElement usage.
Compute host binding security contexts against possible concrete hosts and defer URL versus ResourceURL selection to runtime when necessary. Resolve dynamic root host TNodes to their native tag before sanitizer and security-sensitive attribute checks.

The control flow migration determines whether an `*ngIf` uses a `then`
and/or `else` clause by regex matching the raw microsyntax string for
the literal keywords `then`/`else`. The regexes only checked that the
keyword was preceded by a non-word character, but not that it was
followed by one.
As a result, a template reference name that merely starts with `then`
(e.g. `else thenBlock`) or `else` was misidentified as the `then`/`else`
keyword itself. This caused the migration to take the wrong code path
(e.g. then+else instead of else-only), which in turn made
`getTemplateName()` compute a `slice(start, end)` with `start > end`,
producing an empty template name. That empty placeholder was never
resolved and was silently emitted as an invalid
`<ng-template [ngTemplateOutlet]=""></ng-template>`, dropping the
original template content without any warning.
Add a negative lookahead `(?![\w\d])` to both regexes so `then`/`else`
are only matched as whole keywords, not as a prefix of a longer
template reference name.
Fixes#69914
Reformats the TEST_CASES.json files touched by the following change so they
satisfy the repo's prettier check (short inputFiles/files arrays collapsed to a
single line). Pure formatting; the parsed JSON is unchanged. Split into its own
commit so the coverage change that follows is easy to review.
We were raising the suggestion about enabling `strictTemplates` when `strictTemplates` is ommitted, however the option is now enabled by default.
Fixes#69905.
## Summary
This PR adds v22.x and v23 release dates. It also changes Angular's release cadence to a yearly cycle.
## Why we are making this change
The community has long requested less frequent major releases due to the impact of breaking changes and upgrades for their projects as well as for enterprise customers. Additionally, a longer release cycle provides increased API stability for developers using agentic workflows, while still delivering a reasonable cadence of API upgrades and migrations.
A leading UTF-8 byte order mark (U+FEFF) before the first `#` stops the
Markdown parser from recognizing the heading, so the guide renders its
title as a paragraph and drops the standard docs header. The character
is invisible, so it cannot be caught in review.
Add a check in the guides generation pipeline that throws when a source
file starts with a BOM, failing the build with the offending file name.
This sits alongside the existing unknown-anchor check and prevents the
regression fixed in #69889 from recurring.
The ng-container and binding template guide files each began with a
UTF-8 BOM (EF BB BF) before the leading `#`. The docs markdown parser
only promotes `#` to an H1 when it is the first character on the line,
so the BOM demoted the title to paragraph text (`<p># ...</p>`) and the
standard docs header (breadcrumbs, page title, edit button) never
rendered.
Stripping the BOM restores `#` as the first character, so both pages
now generate the proper `<header class="docs-header">` block. Verified
by rebuilding //adev/src/content/guide/templates:templates and
inspecting the generated HTML.
Fixes#69889
Separate direct from curried calls of `describe`/`it` modifiers
(direct: `skip`, `only`, etc.; curried: `runIf`, `each`, etc.)
and perform the required patching to them.
Fixes: #69748
Propagate the crossorigin attribute from priority NgOptimizedImage hosts to SSR-generated preload links. Keep preload and image requests in the same credentials mode to avoid an anonymous image issuing an earlier credentialed request.
Twitter is now X. In the custom-route-matcher guide, point the author-credit
link at x.com and refer to an "X (formerly Twitter) handle" (clarified once,
then "X handle"), matching the "X (formerly Twitter)" wording already used in
the footer, navigation, and update guide.
Store the trigger kind before each switch and assign the value to `never` in the fallback branch.
This removes the `any` casts and makes the switches exhaustive. Adding a new `DeferTriggerKind` without handling it in either phase now produces a TypeScript compilation error.
Runtime behavior and error messages remain unchanged.
The angle-guessing minigame's result popup personifies your score with a
hand-drawn stick-figure that changes expression by accuracy. Now that Angie
appears across adev — the 404 page, docs search, the embedded editor, the
tutorial intros and completions — give the minigame the same treatment so
its result feels consistent with the rest of the docs.
Replace the result reactor's stick-figure illustration with an Angie pose
keyed to accuracy (seven tiers, superhero down to angry). She is revealed
once the accuracy counter finishes counting up, popping in beside a speech
bubble that carries the round's existing quote. The result popup is widened
so Angie and the bubble sit side by side, and the share link is moved from
twitter.com to x.com.
This removes the previous hand-drawn stick-figure result art. NG the Angle,
the interactive character in the play area, is unchanged.
Previously, the `pending()` status on a field's `ValidationState` only checked if the field itself or its immediate children had a pending asynchronous validator by directly inspecting `asyncErrors()`. This meant that a pending asynchronous validator deep within a nested form (e.g. on a grand-child) would not correctly bubble the `pending` state up to the root form.
