I think a description of the changes to how the history stack is displayed should also be included and circulated …when users have 8 to 10 modules still hanging around after compressing and then the order of them can change depending on which one you select in that group before you hit compress…in that first group of 8-10…I think there will be a million questions from users esp given this behaviour is now combined with the ability to change processing order of the modules…
