Skype has updated their Android app today and with it brings a few bug fixes and a few new features. Battery use has been improved upon allowing you to leave Skype running all the time and not waste tons of battery while still being to sign in. However for those who still like to sign out it is now easier than ever because Skype always remembers your login details to make it easier to sign in next time.
Another improvement is the ability to preview web links just like you can on Mac or iOS. This allows you to get a small preview of the link you have been sent without needing to click on it. For example a YouTube video will show the thumbnail image within the Skype chat box.
