Skype version 4 for Windows was released on the 4th of Febuary 2009. Version 4 presented a new UI layout never seen before in any stable Skype release - changes such as a horizontal rectangular layout have been introduced, a change to the old IM client like vertical rectangular window. But, inside the app, not a lot has changed.
Seeing as this quite the "cosmetic" release, i'm going to poke around at the features I like and dislike about the new Skype UI - and how it affects me as a casual user of the app.
Every time I tried to play a game on Steam with Skype running it minimized it, and the only fix was reverting back to the "Classic Windows" theme in the settings. That feature, in my opinion, is shit, unnecessary and an incy bit annoying.
The calling screen has impoved loads. It looks a lot sleeker, and displays more information about your current call that it used to. You can view your contact list at the same time, and easily detach the call from the contacts list to get a more compact view.
Call volume and stuff is easier to get to, and the hold call and sound settings are a context menu away.
So, there you have it. Skype 4 in a nutshell. It's definitely better than any previous release, however little seems to have changed feature-wise - this was basically a redesign in software terms.
