Mac only: Fixed a bug that caused scrapbooks to save to the app bundle instead of the users’ application support directory or any custom directory.
If you have created scrapbooks in LayOut 2015, you will need to copy them from/Applications/SketchUp 2015/ LayOut.app/Contents/Resources/English.lproj/Scrapbooks/ before you delete the old version of LayOut, or they will be lost (if you are running a localized build, replace ‘English.lproj’ with the localized version you have installed).
