Assets/Fungus/Docs/CHANGELOG.txt

@@ -9,6 +9,7 @@ Unreleased
  - Dialog ClickAnywhere not supports ignore click delay. Thanks to breadnone.
  - SetNextLineFlag only flags if Dialog is actually active/writing. Thanks to breadnone. 
  - TextAdapter with TMPro, now forces mesh update on text change. Fixes cases where a Say/Writer would expect RevealedCharacters to be current but would be previous frame stale value.
+ - Camera Fade clears local callback before execution, fixes #973.
 
 ## Changed
  - Block will LogError when an exception is caught from a Command being Executed.
