Summary

ReactiveUI.Primitives 9.0.0 is a major version because the SubscribeSafe operator changes. A lone delegate passed to SubscribeSafe is now the onNext handler, as in System.Reactive.

Why it changed

• SubscribeSafe had error-only overloads, SubscribeSafe(onError) and SubscribeSafe(onError, onCompleted), and no onNext-only overload.
• So source.SubscribeSafe(x => Use(x)) compiled and bound the lambda as the error handler.
• Every value, including the initial one, was silently dropped.

What to change

• With a lone onNext handler and no error handler, a source error is rethrown with its original stack.
• The (onNext, onError) and (onNext, onError, onCompleted) overloads are unchanged.
• If you passed one lambda to SubscribeSafe to handle errors, you now get a compile error, or the lambda receives values. Rename the call to SubscribeSafeErrors.
