Most enterprise software companies write up a special Release Notes document to accompany a new version of their product. The majority of Release Notes that I have come across are filled with the obligatory "fixed bugs" and "new features" lists.
I know for a fact that most customers do read Release Notes. They need to in order to check for bug fixes that impact their implementation or to learn about features that might help their users.
What a great opportunity to shine a spotlight on your application, regardless of what's new or fixed?
Who says the Release Notes have to be exclusively about that release? Why not emphasize new features in the context of existing ones? Or highlight fixed bugs and how they now allow for increased productivity in your product.
In other words, give the facts but don't miss an opportunity to show your customers the bigger picture.
