Added

• InMemoryVariableStorage now shows the current state of variables in the Inspector. (@radiatoryang)
• InMemoryVariableStorage now supports saving variables to file, and to PlayerPrefs. (@radiatoryang)

Changed

• Inline expressions (for example, One plus one is {1+1}) are now expanded.
• Added Help URLs to various classes. (@radiatoryang)
• The Upgrader window (Window -> Yarn Spinner -> Upgrade Scripts) now uses the updated Yarn Spinner upgrade tools. See Yarn Spinner 2.0.0-beta2 release notes for more information on the upgrader.
• Fixed an issue where programs failed to import if a source script reference is invalid
• Fixed an issue where the DialogueUI would show empty lines when showCharacterName is false and the line has no character name

Removed

• The [[Destination]] and [[Option|Destination]] syntax has been removed from the language.
  • This syntax was inherited from the original Yarn language, which itself inherited it from Twine.
  • We removed it for four reasons:
    • it conflated jumps and options, which are very different operations, with too-similar syntax;
    • the Option-destination syntax for declaring options involved the management of non-obvious state (that is, if an option statement was inside an if branch that was never executed, it was not presented, and the runtime needed to keep track of that);
    • it was not obvious that options accumulated and were only presented at the end of the node;
    • finally, shortcut options provide a cleaner way to present the same behaviour.
  • We have added a <<jump Destination>> command, which replaces the [[Destination]] jump syntax.
  • No change to the bytecode is made here; these changes only affect the compiler.
  • Instead of using [[Option|Destination]] syntax, use shortcut options instead. For example:

// Before
Kim: You want a bagel?
[[Yes, please!|GiveBagel]]
[[No, thanks!|DontWantBagel]]

// After
Kim: You want a bagel?
-> Yes, please!
  <<jump GiveBagel>>
-> No, thanks!
  <<jump DontWantBagel>>

• InMemoryVariableStorage no longer manages 'default' variables (this concept has moved to the Yarn Program.) (@radiatoryang)
