Version 3.1.0

• Added [Serializable] attribute to options.
• Added unit tests (e.g. official support) for default(Option<T>) etc. (for use in optional parameters etc.)

Version 3.0.0

Note: Although this is a major version increment, there are no breaking changes.

• Added support for iterating over options in foreach loops.
• Added ToEnumerable() method, for easily converting options to enumerables.
• Added an Else method, for easy fallback to another option in case of none.
• Added NoneWhen() method, as an opposite of SomeWhen.
• Added possibility of using exception value in Or and ValueOr for Option<T, TException>.

Version 2.2.0

• Option<T> and Option<T, TException> now implements IEquatable for improved performance.
• == and != operators have been added for convenience.

Version 2.1.0

• Switched to semantic versioning scheme
  • And: I decided to rip away the leading zero, as it was basically used incorrectly

• Remembered XML comments in the nuget package :)

Version 0.2.0.0
