Where I can download older version of RoundCorner for Sketchup 2015?

Using Sketchup 2015, installed latest version or RoundCorner do not support.
Where I can download previous version suitable for Sketchup 2015?

Thank you!

I don’t know why you ask here rather than at sketchucation where all Fredo plugins are hosted.
Fredo kindly offers archived versions where necessary, round corner can be found by clicking here.
