+
+
+### BREAKING CHANGES
+
+* **packaging:** In v10, IE 9, 10, and IE mobile support was deprecated. In v11, Angular framework removes IE 9,
+10, and IE mobile support completely.
+Supporting outdated browsers like these increases bundle size, code complexity, and test load,
+and also requires time and effort that could be spent on improvements to the framework.
+For example, fixing issues can be more difficult, as a straightforward fix for modern browsers
+could break old ones that have quirks due to not receiving updates from vendors.
+* **platform-webworker:** @angular/platform-webworker and @angular/platform-webworker-dynamic
+have been removed as they were deprecated in v8
+* **common:** The `slice` pipe now returns `null` for the `undefined` input value,
+which is consistent with the behavior of most pipes. If you rely on
+`undefined` being the result in that case, you now need to check for it
+explicitly.
+* **common:** The typing of the `keyvalue` pipe has been fixed to report that for
+input objects that have `number` keys, the result will contain the
+string representation of the keys. This was already the case and the
+code has simply been updated to reflect this. Please update the
+consumers of the pipe output if they were relying on the incorrect
+types. Note that this does not affect use cases where the input values
+are `Map`s, so if you need to preserve `number`s, this is an effective
+way.
+* **common:** The signatures of the number pipes now explicitly state which types are
+accepted. This should only cause issues in corner cases, as any other
+values would result in runtime exceptions.
+* **common:** The signature of the `date` pipe now explicitly states which types are
+accepted. This should only cause issues in corner cases, as any other
+values would result in runtime exceptions.
+* **common:** The async pipe no longer claims to return `undefined` for an input that
+was typed as `undefined`. Note that the code actually returned `null` on
+`undefined` inputs. In the unlikely case you were relying on this,
+please fix the typing of the consumers of the pipe output.
+* **common:** The case conversion pipes no longer let falsy values through. They now
+map both `null` and `undefined` to `null` and raise an exception on
+invalid input (`0`, `false`, `NaN`) just like most "common pipes". If
+your code required falsy values to pass through, you need to handle them
+explicitly.
+* **router:** While the new parameter types allow a variable of type
+`NavigationExtras` to be passed in, they will not allow object literals,
+as they may only specify known properties. They will also not accept
+types that do not have properties in common with the ones in the `Pick`.
+To fix this error, only specify properties from the `NavigationExtras` which are
+actually used in the respective function calls or use a type assertion
+on the object or variable: `as NavigationExtras`.
+* **router:** This commit changes the default value of
+`relativeLinkResolution` from `'legacy'` to `'default'`. If your
+application previously used the default by not specifying a value in the
+`ExtraOptions` and uses relative links when navigating from children of
+empty path routes, you will need to update your `RouterModule` to
+specifically specify `'legacy'` for `relativeLinkResolution`.
+See https://angular.io/api/router/ExtraOptions#relativeLinkResolution
+for more details.

+* **router:** add migration to update calls to navigateByUrl and createUrlTree with invalid parameters ([#38825](https://github.com/angular/angular/issues/38825)) ([7849fdd](https://github.com/angular/angular/commit/7849fdd)), closes [#38227](https://github.com/angular/angular/issues/38227)
+* **service-worker:** add the option to prefer network for navigation requests ([#38565](https://github.com/angular/angular/issues/38565)) ([a206852](https://github.com/angular/angular/commit/a206852)), closes [#38194](https://github.com/angular/angular/issues/38194)
+
+
+### BREAKING CHANGES
+
+* **core:** If you call `TestBed.overrideProvider` after TestBed initialization, provider overrides are not applied. This
+behavior is consistent with other override methods (such as `TestBed.overrideDirective`, etc) but they
+throw an error to indicate that, when the check was missing in the `TestBed.overrideProvider` function.
+Now calling `TestBed.overrideProvider` after TestBed initialization also triggers an
+error, thus there is a chance that some tests (where `TestBed.overrideProvider` is
+called after TestBed initialization) will start to fail and require updates to move `TestBed.overrideProvider` calls
+before TestBed initialization is completed.

+
+
+### BREAKING CHANGES
+
+* **router:** This change corrects the argument order when calling
+RouteReuseStrategy#shouldReuseRoute. Previously, when evaluating child
+routes, they would be called with the future and current arguments would
+be swapped. If your RouteReuseStrategy relies specifically on only the future
+or current snapshot state, you may need to update the shouldReuseRoute
+implementation's use of "future" and "current" ActivateRouteSnapshots.
+* **common:** The locale data API has been marked as returning readonly arrays, rather
+than mutable arrays, since these arrays are shared across calls to the
+API. If you were mutating them (e.g. calling `sort()`, `push()`, `splice()`, etc)
+then your code will not longer compile. If you need to mutate the array, you
+should now take a copy (e.g. by calling `slice()`) and mutate the copy.
+* **common:** When passing a date-time formatted string to the `DatePipe` in a format that contains
+fractions of a millisecond, the milliseconds will now always be rounded down rather than
+to the nearest millisecond.
+
+Most applications will not be affected by this change. If this is not the desired behaviour
+then consider pre-processing the string to round the millisecond part before passing
+it to the `DatePipe`.

-Support for IE 9 and 10 has been deprecated, as well as support for IE Mobile. These will be dropped in a future version.
-Supporting outdated browsers like these increases bundle size, code complexity, and test load, and also requires time and effort that could be spent on improvements to the framework.
-For example, fixing issues can be more difficult, as a straightforward fix for modern browsers could break old ones that have quirks due to not receiving updates from vendors.
-
-The final decision was made on three key points:
-* __Vendor support__: Microsoft dropped support of IE 9 and 10 on 1/12/16, meaning they no longer provide security updates or technical support. Additionally, Microsoft dropped support for Windows 10 Mobile in December 2019.
-* __Usage statistics__: We looked at usage trends for IE 9 and 10 (as well as IE Mobile) from various sources and all indicated that usage percentages were extremely small (fractions of 1%).

 {@a style-sanitization}
 ### Style Sanitization for `[style]` and `[style.prop]` bindings
 Angular used to sanitize `[style]` and `[style.prop]` bindings to prevent malicious code from being inserted through `javascript:` expressions in CSS `url()` entries. However, most modern browsers no longer support the usage of these expressions, so sanitization was only maintained for the sake of IE 6 and 7. Given that Angular does not support either IE 6 or 7 and sanitization has a performance cost, we will no longer sanitize style bindings as of version 10 of Angular.

 Though the `@NgModule` decorator has an `entryComponents` array, most of the time
 you won't have to explicitly set any entry components because Angular adds components listed in `@NgModule.bootstrap` and those in route definitions to entry components automatically. Though these two mechanisms account for most entry components, if your app happens to bootstrap or dynamically load a component by type imperatively,
 you must add it to `entryComponents` explicitly.
