In that case it's work in progress and you don't need a license as already stated
Quote:
You don't have to get a license if: - your project is open source - you are posting bugs of your project or Shade-C - you are helping other Shade-C users and have to post screenshots/videos to do so - you are publishing work in progress material of your project - you contribute(d) something to the Shade-C project
Additionally you were using an older version which WAS and IS still free.
