+                 
+                Celeste Studio was recently fully rewritten, bringing lots of new features and proper cross-platform compatibility for Windows, Linux and macOS.
+                With this change, the executable also moved slightly from "<celeste-install>/Celeste Studio.exe" to it's own directory under "<celeste-install>/CelesteStudio/".
+
+                Make sure to update any shortcuts you have and no longer use Wine / Mono if you were using that. 
+
+                If you experience any issues, please report those to have them fixed.
+                
+                NOTE: 
+                    There are known issues with Celeste Studio v3 on Windows 7.
+                    If possible, try to update to at least Windows 10, otherwise it is recommended to continue using Celeste Studio v2 with the latest CelesteTAS v3.39.x in the mean time. (Only major bugs will be fixed in that version! No features will be backported!)
