Features bazel: allow ng_module rules to control whether type checking is enabled (#21460) (cffa0fe) core: add binding name to content changed error (#20352) (d3bf54b) forms: handle string with and without line boundary on pattern validator (#19256) (54bf179)

Performance Improvements ivy: add missing dom element in render3_function tree benchmark (#21476) (9b5a485)

5.2.1 (2018-01-17) Bug Fixes animations: fix increment/decrement aliases example (#18323) (48c1898) benchpress: should still support selenium_webdriver < 3.6.0 (#21477) (3c6a506) common: set correct timezone for ISO8601 dates in Safari (#21506) (8e9cd57), closes #21491 compiler: cache external reference resolution (#21359) (c32e833) compiler: make .ngsummary.json files idempotent (#21448) (a931a41) core: fix chained http call (#20924) (54e7576), closes #20921 language-service: Clear caches when program changes (#21337) (cc9419d), closes #19405 service-worker: properly handle invalid hashes in all scenarios (#21288) (51eb3d4)

Features core: add binding name to content changed error (#20352) (4556532) forms: handle string with and without line boundary on pattern validator (#19256) (75f8522)

5.2.0 (2018-01-10) Bug Fixes bazel: Give correct module names for ES6 output (#21320) (9728dce), closes #21022 benchpress: forward compat with selenium_webdriver 3.6.0 (#21399) (6040ee3) benchpress: work around missing events from Chrome 63 (#21396) (fa03ae1) common: export currencies via getCurrencySymbol (#20983) (fecf768) Note: Due to an animation fix back in 5.1.1 (c2b3792) which allows for nested :leave queries to work within animation sequences, all elements that are dynamically inserted (*ngIf, *ngFor, etc…) now contain the special CSS class: “ng-starinserted”. This may cause failures within unit tests if there are any assertions that match against element.className directly. (An easy fix for this is to match using a regular expression instead of asserting the className string directly.)

BREAKING CHANGES compiler: Angular now requires TypeScript 2.4.x. compiler: split compiler and core. @angular/platform-server now additionally depends on @angular/platformbrowser-dynamic as a peer dependency. (#18683) (0cc77b4) platformXXXX() no longer accepts providers which depend on reflection. Specifically the method signature went from Provider[] to StaticProvider[] .

Example: Before: [ MyClass, {provide: ClassA, useClass: SubClassA} ]

After: [ {provide: MyClass, deps: [Dep1,...]}, {provide: ClassA, useClass: SubClassA, deps: [Dep1,...]} ]

NOTE: This only applies to platform creation and providers for the JIT compiler. It does not apply to @Component or @NgModule provides declarations. Benchpress note: Previously Benchpress also supported reflective provides, which now require static providers. I18n Changes (@angular/common) Because of multiple bugs and browser inconsistencies, we have dropped the intl api in favor of data exported from the Unicode Common Locale Data Repository (CLDR). Unfortunately we had to change the i18n pipes (date, number, currency, percent) and there are some breaking changes. I18n pipes:

Breaking change: By default Angular now only contains locale data for the language en-US , if you set the value of LOCALE_ID to another locale, you will have to import new locale data for this language because we don't use the intl API anymore. Features: you don't need to use the intl polyfill for Angular anymore. all i18n pipes now have an additional last parameter locale which allows you to use a specific locale instead of the one defined in the token LOCALE_ID (whose default value is en-US ). the new locale data extracted from CLDR are now available to developers as well and can be used through an API (which should be especially useful for library authors). you can still use the old pipes for now, but their names have been changed and they are no longer included in the CommonModule . To use them, you will have to import the DeprecatedI18NPipesModule after the CommonModule (the order is important): import { NgModule } from '@angular/core'; import { CommonModule, DeprecatedI18NPipesModule } from '@angular/common'; @NgModule({ imports: [ CommonModule, // import deprecated module after DeprecatedI18NPipesModule ] }) export class AppModule { }

Don't forget that you will still need to import the intl API polyfill if you want to use those deprecated pipes. Date pipe

Breaking changes: the predefined formats ( short , shortTime , shortDate , medium , ...) now use the patterns given by CLDR (like it was in AngularJS) instead of the ones from the intl API. You might notice some changes, e.g. shortDate will be 8/15/17 instead of 8/15/2017 for en-US . the narrow version of eras is now GGGGG instead of G , the format G is now similar to GG and GGG . the narrow version of months is now MMMMM instead of L , the format L is now the short standalone version of months. the narrow version of the week day is now EEEEE instead of E , the format E is now similar to EE and EEE . the timezone z will now fallback to O and output GMT+1 instead of the complete zone name (e.g. Pacific Standard Time ), this is because the quantity of data required to have all the zone names in all of the existing locales is too big. the timezone Z will now output the ISO8601 basic format, e.g. +0100 , you should now use ZZZZ to get GMT+01:00 .

Features new predefined formats long , full , longTime , fullTime . the format yyy is now supported, e.g. the year 52 will be 052 and the year 2017 will be 2017 . standalone months are now supported with the formats L to LLLLL . week of the year is now supported with the formats w and ww , e.g. weeks 5 and 05 . week of the month is now supported with the format W , e.g. week 3 . fractional seconds are now supported with the format S to SSS . day periods for AM/PM now supports additional formats aa , aaa , aaaa and aaaaa . The formats a to aaa are similar, while aaaa is the wide version if available (e.g. ante meridiem for am ), or equivalent to a otherwise, and aaaaa is the narrow version (e.g. a for am ). extra day periods are now supported with the formats b to bbbbb (and B to BBBBB for the standalone equivalents), e.g. morning , noon , afternoon , .... the short non-localized timezones are now available with the format O to OOOO . The formats O to OOO will output GMT+1 while the format OOOO will be GMT+01:00 . the ISO8601 basic time zones are now available with the formats Z to ZZZZZ . The formats Z to ZZZ will output +0100 , while the format ZZZZ will be GMT+01:00 and ZZZZZ will be +01:00 . Bug fixes the date pipe will now work exactly the same across all browsers, which will fix a lot of bugs for safari and IE. eras can now be used on their own without the date, e.g. the format GG will be AD instead of 8 15, 2017 AD . Currency pipe

Breaking change: the default value for symbolDisplay is now symbol instead of code . This means that by default you will see $4.99 for en-US instead of USD4.99 previously. Deprecation: the second parameter of the currency pipe ( symbolDisplay ) is no longer a boolean, it now takes the values code , symbol or symbol-narrow . A boolean value is still valid for now, but it is deprecated and it will print a warning message in the console. Features: you can now choose between code , symbol or symbol-narrow which gives you access to more options for some currencies (e.g. the canadian dollar with the code CAD has the symbol CA$ and the symbol-narrow $ ). Percent pipe

Breaking change if you don't specify the number of digits to round to, the local format will be used (and it usually rounds numbers to 0 digits, instead of not rounding previously), e.g. {{ 3.141592 | percent }} will output 314% for the locale en-US instead of 314.1592% previously.

Deprecated code compiler: The method ngGetContentSelectors() has been removed as it was deprecated since v4. Use ComponentFactory.ngContentSelectors instead. compiler: the compiler option enableLegacyTemplate is now disabled by default as the element was deprecated since v4. Use instead. The option enableLegacyTemplate and the element will both be removed in Angular v6. compiler: the option useDebug for the compiler has been removed as it had no effect and was deprecated since v4.

BREAKING CHANGES Perviously, any provider that had an ngOnDestroy lifecycle hook would be created eagerly. Now, only classes that are annotated with @Component, @Directive, @Pipe, @NgModule are eager. Providers only become eager if they are either directly or transitively injected into one of the above. This also makes all useValue providers eager, which should have no observable impact other than code size. EXPECTED IMPACT: Making providers eager was an incorrect behavior and never documented. Also, providers that are used by a directive / pipe / ngModule stay eager. So the impact should be rather small. DebugNode.source no longer returns the source location of a node. Closes 14013 core: (since v4 rc.1) Renderer2.setStyle no longer takes booleans but rather a bit mask of flags.

4.0.0-rc.1 (2017-02-24) We are excited to share 4.0.0-RC.1 with the community. This is a feature-complete pre-release of 4.0.0. Upgrade to get to know the new features to be released in 4.0.0, and to help us validate the release. It’s important to note that this release has been tested extensively. All Angular applications within Google use the master branch of Angular, so every commit is tested and validated at scale prior to any release.

We Need Your Help Please give this RC a try and test it with your projects! We have spent a significant amount of time working to ensure that this release is backwards compatible and will work with your existing code, but you may have use cases we haven’t anticipated. If you are broken by this release, let us know so that we can look into it right away. We are also looking for feedback related to the ergonomics of any newly added APIs.

What’s New View Engine We’ve made changes under the hood to what AOT generated code looks like. These changes should reduce the size of the generated code for your components by more than half in some cases. Read the Design Doc for the View Engine updates.

Enhanced *ngIf syntax Our template binding syntax now supports a couple helpful changes. You can now use an if/else style syntax, and assign local variables such as when unrolling an observable. Loading... {{ user.name }}

Animation Package We have pulled Animations into their own package. This means that if you don’t use Animations, this extra code will not end up in your production bundles. This also allows you to more easily find documentation and to take better advantage of autocompletion. If you do need animations, libraries like Material will automatically import the module (once you install it via NPM), or you can add it yourself to your main NgModule.

TypeScript 2.1 We’ve updated Angular to a more recent version of TypeScript. This will improve the speed of ngc and you will get better type checking throughout your application.

StrictNullChecks Angular is now compliant with TypeScript’s StrictNullChecks. This means that you can enable StrictNullChecks in your project, if desired.

Universal Universal, the project that allows developers to run Angular on a server, is now up to date with Angular again, and has been adopted by the Angular team. This release now includes the results of the work from the Universal team over the last few months. The majority of the Universal code is now in platform-server. To learn more about this change, take a look the new renderModuleFactory method, or Rob Wormald’s Demo Repository. More documentation is forthcoming.

Flat ES Modules (Flat ESM / FESM) We now ship flattened versions of our modules ("rolled up" version of our code in the EcmaScript Module format, see example file). This format should help tree-shaking, help reduce the size of your generated bundles, and speed up build, transpilation, and loading in the browser in certain scenarios.

ES2015 Builds We now also ship our packages in the ES2015 Flat ESM format. This option is experimental and opt-in (configure your webpack to resolve "es2015" property in package.json over the regular "module" property).

Known Issues The following is a list of known issues that will be fixed in the next rcs. Source maps are missing in npm packages Generated bundles will be larger temporarily while we validate new code paths and remove old ones angular.io docs have not been updated to reflect API changes in 4.0 legacy UMD bundles don't have correct RxJS mappings when running in ES5 mode without a module system

Installing RC.1 We have two main ways to update. If you have an existing project, you should be able to run: On Linux/Mac: npm install @angular/{common,compiler,compiler-cli,core,forms,http,platform-browser,platformbrowser-dynamic,platform-server,router,animations}@next --save On Windows: npm install @angular/[email protected] @angular/[email protected] @angular/[email protected] @angular/[email protected] @angular/[email protected] @angular/[email protected] @angular/[email protected] @angular/platform-browser-dyna[email protected] @angular/[email protected] @angular/[email protected] @angular/[email protected] --save

Then run whatever ng serve or npm start command you normally use, and everything should work. Please ensure that you are using Typescript v2.1.6 or higher. If you rely on Animations you’ll also need to install the animations package @angular/animations and import the new BrowserAnimationsModule from @angular/platform-browser/animations in your root NgModule. Without this, your code will compile and run, but animations won’t activate. Imports from @angular/core were deprecated, use imports from the new package import { trigger, state, style, transition, animate } from '@angular/animations'; .

What's next? We have three more release candidates scheduled before our planned GA the week of March 22. In the meantime we'll be looking for your feedback, fixing bugs and working on docs.

Code Refactoring core: deprecate RootRenderer / Renderer (ccb636c) core: change abstract classes for interfaces (#12324) (ee747f7), closes #10083

Performance Improvements distribute smaller bundled code and include es2015 bundle (de795ea)

BREAKING CHANGES core: Because all lifecycle hooks are now interfaces the code that uses 'extends' keyword will no longer compile. Introduced by (ee747f7). To migrate the code follow the example below: Before: @Component() class SomeComponent extends OnInit {}

After: @Component() class SomeComponent implements OnInit {}

Based on our research we don't expect anyone to be affected by this change. RootRenderer cannot be used any more, use RendererFactoryV2 instead. Introduced by (ccb636c).

Note: Renderer can still be injected/used, but is deprecated. Note: the 4.0.0-rc.0 release on npm accidentally omitted one bug fix, so we cut rc.1 instead. oops :-)

(96d06f7)

DEPRECATIONS core: KeyValueDifferFactory and IterableDifferFactory no longer have ChangeDetectorRef as a parameter. It was not used and has been there for historical reasons. If you call DifferFactory.create(...) remove the ChangeDetectorRef argument. Introduced by (#14311).

BREAKING CHANGES common: Classes that derive from AsyncPipe and override transform() might not compile correctly. The much more common use of async pipe in templates is unaffected. We expect no or little impact on apps from this change, file an issue if we break you. Introduced by (#14367) (4da7925). Mitigation: Update derived classes of AsyncPipe that override transform() to include the type parameter overloads.

Performance Improvements upgrade: unregister $doCheck watcher when destroying upgraded component (#14303) (94312f0) Don’t subclass Error; resulting in smaller binary (#14160) (c33fda2)

BREAKING CHANGES Angular 4 will support only TypeScript 2.1, so we no longer provide backwards compatibility to TS 1.8.

Performance Improvements use abstract keyword where possible to decrease file size. (#14112) (670b680) core simplify ReflectiveInjector by removing code for Dart implementation (#14126) (670b680)

BREAKING CHANGES common: A definition of Iterable is now required to correctly compile Angular applications. Support for Iterable is not required at runtime but a type definition Iterable must be available. NgFor , and now NgForOf , already supports Iterable at runtime. With this change the type definition is updated to

reflect this support. Migration: add "es2015.iterable.ts" to your tsconfig.json "libs" fields. Part of #12398 upgrade: Previously, upgrade/static/downgradeInjectable returned an array of the form: ['dep1', 'dep2', ..., function factory(dep1, dep2, ...) { ... }]

Now it returns a function with an $inject property: factory.$inject = ['dep1', 'dep2', ...]; function factory(dep1, dep2, ...) { ... }

It shouldn't affect the behavior of apps, since both forms are equally suitable to be used for registering AngularJS injectable services, but it is possible that type-checking might fail or that current code breaks if it relies on the returned value being an array.

DEPRECATIONS OpaqueToken is now deprecated, use InjectionToken instead. Injector.get(token: any, notFoundValue?: any): any is now deprecated use the same method which is now

overloaded as Injector.get(token: Type|InjectionToken, notFoundValue?: T): T;

BREAKING CHANGES core: - Because injector.get() is now parameterize it is possible that code which used to work no longer type checks. Example would be if one injects Foo but configures it as {provide: Foo, useClass: MockFoo} . The injection instance will be that of MockFoo but the type will be Foo instead of any as in the past. This means that it was possible to call a method on MockFoo in the past which now will fail type check. See this example: class Foo {} class MockFoo extends Foo { setupMock(); } var PROVIDERS = [ {provide: Foo, useClass: MockFoo} ]; ... function myTest(injector: Injector) { var foo = injector.get(Foo); // This line used to work since `foo` used to be `any` before this // change, it will now be `Foo`, and `Foo` does not have `setUpMock()`. // The fix is to downcast: `injector.get(Foo) as MockFoo`. foo.setUpMock(); }

BREAKING CHANGES core: - IterableChangeRecord is now an interface and parameterized on . This should not be an issue unless your code does new IterableChangeRecord which it should not have a reason to do. KeyValueChangeRecord is now an interface and parameterized on . This should not be an issue unless your code

does new KeyValueChangeRecord which it should not have a reason to do.

DEPRECATION Deprecate ngOutletContext . Use ngTemplateOutletContext instead. CollectionChangeRecord is renamed to IterableChangeRecord . CollectionChangeRecord is aliased to IterableChangeRecord and is marked as @deprecated . It will be removed in v6.x.x .

Deprecate DefaultIterableDiffer as it is private class which was erroneously exposed. Deprecate KeyValueDiffers#factories as it is private field which was erroneously exposed. Deprecate IterableDiffers#factories as it is private field which was erroneously exposed.

Note Due to regression in the 2.3.0 release that was fixed by #13464, components that have been compiled using 2.3.0 and published to npm will need to be recompiled and republished. The >=2.3.1 compiler will issue is the following error if it encounters components compiled with 2.3.0: Unsupported metadata version 2 for module ${module}. This module should be compiled with a newer version of ngc . We are adding more tests to our test suite to catch these kinds of problems before we cut a release.
