1.0.0-beta.1

New

• Added support for C# 8 nullable reference types

Changed

• Replaced GetValueOrDefault with 3 new methods to better support nullability analysis.
  • ValueOrDefault<T>() where T : struct: returns the option's value, or default(T) if the option is None
  • ValueOrNull<T>() where T : class?: returns the option's value, or null if the option is None
  • ValueOr<T>(T defaultValue): returns the option's value, or defaultValue if the option is None
