## 1.1.3-2

#### Fixes

-   Noarg compiler plugin reverted to 1.1.2 behavior: by default, it will not run any initialization code
    from the generated default constructor. If you want to run initializers, you need to enable
    the corresponding option as described in the documentation.
    Note that if a @noarg class has initializers that depend on constructor parameters, you will get incorrect
    compiler behavior, so you shouldn't enable this option if you have such classes in your project.
    This resolves [`KT-18667`](https://youtrack.jetbrains.com/issue/KT-18667) and [`KT-18668`](https://youtrack.jetbrains.com/issue/KT-18668).
