- ts-api-guardian will now error if a new public symbol is added with a stability marker (`@stable`, `@experimental`, `@deprecated`) - DomEventsPlugin and KeyEventsPlugin were removed from public api surface - these classes is an implementation detail - deprecated BROWSER_PROVIDERS was removed completely - `@angular/compiler` was removed from the ts-api-guardian check since this package shouldn't contain anything that users need to directly import - the rest of the api surface was conservatively marked as stable or experimental BREAKING CHANGES: DomEventsPlugin and KeyEventsPlugin previously exported from core are no longer public - these classes are implementation detail. Previously deprecated BROWSER_PROVIDERS was completely removed from platform-browser. Closes #9236 Closes #9235 Ref #9234
