IIRC This is a heads-up message about the use of the FrontWindow API and compatibility with the next major release of Mac OS X.
In the current version of Mac OS X, the menubar is drawn into a window that does not have a corresponding WindowRef. The window is actually created with CoreGraphics window server calls and not by the Carbon Window Manager. The FrontWindow API never returns a WindowRef for the menubar. In the next major release of Mac OS X, the Menu Manager will be creating the menubar window using the Window Manager. The menubar will have a WindowRef. Since the menubar is almost always the topmost visible window, this means that the FrontWindow API will almost always return the menubar window, as will the GetFrontWindowOfClass API when passed the kAllWindowClasses constant. FrontWindow has been a deprecated API for most usages since Mac OS 8.5, when the FrontNonFloatingWindow API and built-in support for floating windows were introduced. However, a lot of apps are still using it, and get away with this in most cases because the app doesn't use floating windows itself. This is no longer going to work. It's very important to review your source code for uses of the FrontWindow and GetFrontWindowOfClass APIs. It's perfectly OK to use these APIs if you really do want the topmost visible window, of whatever kind, perhaps because you're interating over the window list to examine each window. But if your code is calling FrontWindow or GetFrontWindowOfClass(kAllWindowClasses) with the assumption that this will return the active document or dialog window, then you will have a compatibility problem on the next major release of X. You will get back the menubar instead. You should replace such usages with calls to FrontNonFloatingWindow or (preferred) ActiveNonFloatingWindow.
