iTunes 4.2 iTunes 4.2 has been released. You can download it from here or simply use the "Check for iTunes Updates" option from within the iTunes Help Menu. One of the big improvements (to me) is that you can now 'Maximize' the iTunes window. Mac users can tell you that there is no 'Maximize' button within Mac applications. All of us Windows users take it for granted. I suppose enough of us complained, so they added this standard Windows feature to iTunes.
