Breaking Changes

compiler-cli

• Invalid constructors for DI may now report compilation errors

When a class inherits its constructor from a base class, the compiler may now report an error when that constructor cannot be used for DI purposes. This may either be because the base class is missing an Angular decorator such as @Injectable() or @Directive(), or because the constructor contains parameters which do not have an associated token (such as primitive types like string). These situations used to behave unexpectedly at runtime, where the class may be constructed without any of its constructor parameters, so this is now reported as an error during compilation.

Any new errors that may be reported because of this change can be resolved either by decorating the base class from which the constructor is inherited, or by adding an explicit constructor to the class for which the error is reported.

core

• Angular no longer supports Node.js versions 14.[15-19].x and 16.[10-12].x. Current supported versions of Node.js are 14.20.x, 16.13.x and 18.10.x.
• TypeScript versions older than 4.8 are no longer supported. ### forms
• setDisabledState will always be called when a ControlValueAccessor is attached. You can opt-out with FormsModule.withConfig or ReactiveFormsModule.withConfig. ### router
• relativeLinkResolution is no longer configurable in the Router. This option was used as a means to opt out of a bug fix. ## Deprecations ### common
• The DATE_PIPE_DEFAULT_TIMEZONE token is now deprecated in favor of the DATE_PIPE_DEFAULT_OPTIONS token, which accepts an object as a value and the timezone can be defined as a field (called timezone) on that object. ### router
• The RouterLinkWithHref directive is deprecated, use the RouterLink directive instead. The RouterLink contains the code from the RouterLinkWithHref to handle elements with href attributes. ### common | Commit | Description | | -- | -- | | | add provideLocationMocks() function to provide Location mocks (#47674) | | | add <link> preload tag on server for priority img (#47343) | | | Add automatic srcset generation to ngOptimizedImage (#47547) | | | Add fill mode to NgOptimizedImage (#47738) | | | add injection token for default DatePipe configuration (#47157) | ### compiler | Commit | Description | | -- | -- | | | update element schema (#47552) | | | update element schema (#47552) | ### compiler-cli | Commit | Description | | -- | -- | | | add missing period to error message (#47744) | | | exclude abstract classes from strictInjectionParameters requirement (#44615) | | | use @ts-ignore.
