- the `TestBed.flushEffects()` was removed - use

the `TestBed.tick()` instead.

- `provideExperimentalCheckNoChangesForDebug` has several

breaking changes:

* It is renamed to `provideCheckNoChangesConfig`

* The behavior applies to _all_ checkNoChanges runs

* The `useNgZoneOnStable` option is removed. This wasn't found to be generally

more useful than `interval`

- afterRender was renamed to afterEveryRender.

- This commit deprecates `ng-reflect-*` attributes and updates the runtime to stop producing them by default. Please refactor application and test code to avoid relying on `ng-reflect-*` attributes.

To enable a more seamless upgrade to v20, we've added the `provideNgReflectAttributes()` function (can be imported from the `@angular/core` package), which enables the mode in which Angular would be producing those attribites (in dev mode only). You can add the `provideNgReflectAttributes()` function to the list of providers within the bootstrap call.
