-## Notice:
-
-We have released the Go Client v2, with some breaking API changes. Most changes are minor, and can be fixed with relative ease.
-
-The only major issue is that the behavior of the client when a key does not exist has changed. 
-
-It used to return no error, but a `nil` `Record.Bins`. Now it returns `ErrKeyNotFound` error.
-
-This is a significant changes, and you should search your code for all instances of `Bins == nil` and adapt the code accordingly.
-
-Please refer to the [`CHANGELOG.md`](CHANGELOG.md) for details.
