**[Breaking Changes](https://docs.interop.io/browser/getting-started/changelog/4-1/index.html#breaking_changes)**

The `@interopio/widget` library has deprecated compact mode and updated position values. Widget positions now use more specific options like `"top-left"`, `"top-center"`, `"bottom-center"`, etc., replacing the previous `"top"`, `"bottom"`, `"left"`, and `"right"` values.
