Breaking Changes

compiler

• This change will trigger the nullishCoalescingNotNullable and optionalChainNotNullable diagnostics on exisiting projects.
  You might want to disable those 2 diagnotiscs in your tsconfig temporarily.
• data prefixed attribute no-longer bind inputs nor outputs.
• The compiler will throw when there a when inputs, outputs or model are binding to the same input/outputs.
• in variables will throw in template expressions.

compiler-cli

• Elements with multiple matching selectors will now throw at compile time.

core

• The second arguement of appRef.bootstrap does not accept any anymore. Make sure the element you pass is not nullable.
• • TypeScript versions older than 6.0 are no longer supported.
• Leave animations are no longer limited to the element being removed.
• Component with undefined changeDetection property are now OnPush by default. Specify changeDetection: ChangeDetectionStrategy.Eager to keep the previous behavior.
• change AnimationCallbackEvent.animationComplete signature
• ChangeDetectorRef.checkNoChanges was removed. In tests use fixture.detectChanges() instead.
• createNgModuleRef was removed, use createNgModule instead
• ComponentFactoryResolver and ComponentFactory are no longer available. Pass the component class directly to APIs that previously required a factory, such as ViewContainerRef.createComponent or use the standalone createComponentFunction.
• ComponentFactoryResolver and ComponentFactory are no longer available. Pass the component class directly to APIs that previously required a factory, such as ViewContainerRef.createComponent or use the standalone createComponent function.

forms

• min and max validation rules no longer support
  string values. Bound values must be numbers or null.

http

• Use the HttpXhrBackend with provideHttpClient(withXhr) if you want to keep supporting upload progress reports.

platform-browser

• This removes styles when they appear to no longer be used by an associated host. However other DOM on the page may still be affected by those styles if not leveraging ViewEncapsulation.Emulated or if those styles are used by elements outside of Angular, potentially causing other DOM to appear unstyled.
• Hammer.js integration has been removed. Use your own implementation.

router

• The return type for TitleStrategy.getResolvedTitleForRoute
  was previously 'any' while the actual return type could only be either string
  or undefined. The return type now reflects the possible values correctly.
  Code that reads the value may need to be adjusted.

  (cherry picked from commit ad37f52)

• The currentSnapshot parameter in CanMatchFn and the canMatch method of the CanMatch interface is now required. While this was already the behavior of the Router at runtime, existing class implementations of CanMatch must now include the third argument to satisfy the interface.

• paramsInheritanceStrategy now defaults to 'always'

  The default value of paramsInheritanceStrategy has been changed from 'emptyOnly' to 'always'. This means that route parameters are inherited from all parent routes by default. To restore the previous behavior, set paramsInheritanceStrategy to 'emptyOnly' in your router configuration.

• provideRoutes() has been removed. Use provideRouter() or ROUTES as multi token if necessary.

upgrade

• Deprecated getAngularLib/setAngularLib have been removed use getAngularJSGlobal/setAngularJSGlobal instead.

Deprecations

http

• withFetch is now deprecated, it can be safely removed.
• The reportProgress option is deprecated please use reportUploadProgress & reportDownloadProgress instead.
