That certainly would be a nice feature. But, augh, I will tell you, I have not seen one day where there were no changes. These guys are constantly working.
If you want more details on the versions and tools to track changes, try out the SVN Tortoise tool. It is pretty easy to use. After installing Tortoise, you can create a folder to hold the development "trunk." Then, right click the folder name, select SVN Checkout, then provide the URL of repository (
http://joomlacode.org/svn/joomla/development/trunk) and logon with anonymous / no password and you can get updates at anytime you choose. (Plus version numbers.) It's all described on the same page you download the nightly zip file. An idea, anyway!
Hope you are having fun with Joomla!,
