Comment Depending on your target market.. (Score 1) 162
I'm a developer support engineer for a company that sells several SDKs - It is absolutely invaluable tor our customers (and ourselves) to be able to see the change logs as they're depending on our product to work in certain ways and could be interacting with dozens of systems/components.
I can't tell you how many times I've found that a claimed bug in our product was actually an issue in Weblogic or Websphere or Tomcat, etc.. that was corrected in a given fix (sadly, its often a case of customers coming to us and saying "this is a bug" and us diggin in only to find that yes it was a bug in that outdated version of the web application server they're using and they should have been doing their homework..
So both our own change logs and those of others are absolutely crucial in troubleshooting problems.
My personal $0.02: saying "here's what was fixed and when is not going to draw ridicule. However, having your software be a "big magic black box" is likely to alienate highly technical customers.
