I like to keep a printed user manual for reference and have seen that a new version was introduced in July.
Is there any possibility a simple "document change" process can be implemented so it is easy to see what has been changed from the previous issue?
It could be as simple as highlighting changed text in bold or yellow highlight, or something more detailed like change bars and document revision number etc.

Something like this would save the user from having to read through the complete user manual again!
