                    Merging `release` back to `master` is a regular operation you’re free to do, at any time. Usually, you will see conflicts in `notes.md` or `accepted-public-api-changes.json`.

interface NestedType {
    Property<String> getSomeProperty()
}
class Example {
    Property<NestedType> getNestedProperty()

```

This is unnecessary because users will have trouble creating instances of `NestedType` and merging different instances of `NestedType`. It's also more awkward for users to access the properties in the nested property.

If the nested type is a managed type (Gradle can generate its implementation), you can define a nested property with:

        item.setTimestamp(ZonedDateTime.ofInstant(Instant.ofEpochMilli(timestamp), Clock.systemDefaultZone().getZone()));
        return item;
