I’m going through Chapter three and when doing the examples for “Working with variables” I get the following console warning.

`ℹ️ [DEPRECATED]`Variable`is planned for future deprecation. Please consider`BehaviorRelay` as a replacement. Read more at: https://git.io/vNqvx`

Are there any plans to update this portion of the book? And in the meantime has anybody refactored the examples to use `BehaviorRelay` instead of `Variable`?

So far the book has had yearly updates so most likely there will be a new version shortly after RxSwift 5 is out.

There are debates about `Variable` as `BehaviorRelay` is not a complete drop-in replacement. Some, like me, tend to favor keeping `Variable` around. We’ll see what happens next and will update the book accordingly.
