 We highly recommend keeping an eye on when the beta feature you are interested in goes from beta to stable so that you can move from using a beta version of the SDK to the stable version.
 
 If your beta feature requires a `Stripe-Version` header to be sent, use the `stripe.APIVersion` field to set it:
 
+> **Note**
+> The `APIVersion` can only be set in beta versions of the library.

 ```go
 stripe.APIVersion += "; feature_beta=v3"
 ```
