You will find four major changes in this release:
- A new Conversations View is provided. Users can easily track all of their chats in a unified window. Those users who prefer the old view can disable this in the Chat options;
- A new Call View has been added;
- Better call quality
- Improving video call quality and extended support for more cameras.
Other improvements include improved chat synchronization; a new presence and emoticon icons; the ability to store and view phone numbers in a Skype contact's profile; much lower chance Skype for Linux will crash or freeze; chat history loading is now much faster; and support for two new languages: Czech (flag:cz) and Norwegian (flag:no)
Note, the very first time you start Skype for Linux 4.0 might take a few minutes (depending on how lengthy your chat history is). Subsequent starts will load much more quickly.
