Thank you, but my whole complaint is that this information should be presented all in the same place, in the app, without the user having to go information-hunting outside the update process.
Look at Default Folder X's approach to update notification and installation to see one example among many of how this is correctly done.
Everything one can want to know or do about the update - notification that an update is available, current version the user is running, version number of the update, full release notes, and "Install" button - can and should be presented in one window, in the app. One should not have to go anywhere or click anything in order to access all of the above; it should all appear on the user's screen as one with the notification that an update is available.
The way it's done now is like a store selling sandwiches and telling their customers that if they want mayo or mustard or napkins or a drink, those things can all be easily obtained at the convenience store three doors down the street. It's just...inconsiderate of the user.
