18.6.0 is a bugfix release.
- When games change the path of their executables on update, the app now automatically rescans the install folder to find the new location of executable. Developers are encouraged not to do that, as each extra scan makes player wait unnecessarily, but at least it won't prevent the app from launching the games any further.
- The Windows sandbox sometimes choked on the
output_log.txtfile created by some Debug builds of Unity games. These errors are now ignored, since they're harmless. They still appear in the game logs.
