-
-[#778](https://github.com/okta/okta-oidc-js/pull/778) `@okta/okta-auth-js` is updated to version 4.0.0 and `@okta/configuration-validation` is updated to 1.0.0. These updates contain several breaking changes:
-
-- Typescript definitions are now included. If you were providing your own definitions for `@okta/okta-auth-js` or `@okta/configuration-validation` you should remove these locally defined types in favor of the types exported by this library.
-
-- onSessionExpired option has been removed. [TokenManager events](https://github.com/okta/okta-auth-js#tokenmanageronevent-callback-context) can be used to detect and handle token renewal errors.
+### Bug Fixes
