Hi all, I expect many of you know about and may be using this feature, but every time you save a model, Simulink can be configured to prompt you to enter a changelog comment.
See http://www.mathworks.co.uk/help/simulink/ug/managing-model-versions.html#f4-140406 for details On the off chance that some CASPER users might not know about this, it can be very useful, (particularly if, like me, you don't commit your models to version control often enough or you need a gentle reminder to log minor changes to models). Cheers, Jack
