### BREAKING CHANGES
- If you are using `TypeScript 2.7` and `Angular 5` you will need to update to `TypeScript 2.8.1` and `Angular 6.1.0` at a minimum. We were forced to drop support for these in order to provide support for Ivy. These versions are also no longer supported the Angular team either. This has not resulted in a major version change for NGXS due to the fact that it is not our API that has changed, rather a dependency.
