* Extensions `doInUI` and `doInDefault` were replaced in common and available on any supported platform
* Extension `doInIO` replaced into `jvm` and available on any `JVM` platform
* Old extension `safelyWithouException` without `onException` has been replaced by its copy with `onException` and
default value
* New value `defaultSafelyWithoutExceptionHandlerWithNull` which is used in all `*WithoutExceptions` by default
* Analogs of `launch` and `async` for `safely` and `safelyWithoutExceptions` were added
## 0.5.2 ## 0.5.2
