If you were mutating them (e.g. calling `sort()`, `push()`, `splice()`, etc.) -then your code will no longer compile. If you need to mutate the array, you -should now make 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`. -* **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 -types have 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. -* **compiler:** TypeScript 3.9 is no longer supported, please upgrade to TypeScript 4.0. -* **compiler-cli:** Expressions within ICUs are now type-checked again, fixing a regression -in Ivy. This may cause compilation failures if errors are found in -expressions that appear within an ICU. Please correct these expressions -to resolve the type-check errors. -* **core:** `CollectionChangeRecord` has been removed, use `IterableChangeRecord` instead. -* **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. -* **core:** 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. -* **core:** `ViewEncapsulation.Native` has been removed. Use `ViewEncapsulation.ShadowDom` instead. Existing -usages will be updated automatically by `ng update`. -* **forms:** Previously if `FormControl`, `FormGroup` and `FormArray` class instances had async validators -defined at initialization time, the status change event was not emitted once async validators -completed. After this change the status event is emitted into the `statusChanges` observable. -If your code relies on the old behavior, you can filter/ignore this additional status change -event. -* **forms:** Directives in the `@angular/forms` package used to have `any[]` as a type of `validators` and -`asyncValidators` arguments in constructors. Now these arguments are properly typed, so if your -code relies on directive constructor types it may require some updates to improve type safety. -* **forms:** Type of `AbstractFormControl.parent` now includes `null`. `null` is now included in the types of `.parent`. If you don't already have a check for this case, -the TypeScript compiler might complain. A v11 migration exists which adds the non-null assertion -operator where necessary. In an unlikely case your code was testing the parent against `undefined` with strict equality, -you'll need to change this to `=== null` instead, since the parent is now explicitly initialized -with `null` instead of being left `undefined`. -* **platform-server:** If you use `useAbsoluteUrl` to setup `platform-server`, you now need to -also specify `baseUrl`. -We are intentionally making this a breaking change in a minor release, -because if `useAbsoluteUrl` is set to `true` then the behavior of the -application could be unpredictable, resulting in issues that are hard to -discover but could be affecting production environments. -* **platform-webworker:** @angular/platform-webworker and @angular/platform-webworker-dynamic -have been removed as they were deprecated in v8. -* **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" `ActivatedRouteSnapshot`s. -* **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:** The `initialNavigation` property for the options in -`RouterModule.forRoot` no longer supports `legacy_disabled`, -`legacy_enabled`, `true`, or `false` as valid values. -`legacy_enabled` (the old default) is instead `enabledNonBlocking`. -* **router:** `enabled` is deprecated as a valid value for the -`RouterModule.forRoot` `initialNavigation` option. `enabledBlocking` -has been introduced to replace it. -* **router:** `preserveQueryParams` has been removed, use -`queryParamsHandling: "preserve"` instead. -* **router:** If you were accessing the `RouterLink` values of `queryParams`, -`fragment` or `queryParamsHandling` you might need to relax the typing to also -accept `undefined` and `null`.
