"Canonical has upgraded a lot of aspects of Ubuntu 14.04, and the developers are pushing updates every day. The Software Updater has also received a sizable upgrade, making it a lot more user-friendly than ever before.
More and more new users are installing Ubuntu for the first time and not everyone is ready to upgrade the system from a terminal or from a simple interface that only shows what packages will be downloaded and installed.
The new Software Updater is now a lot more user-friendly and shows more details about what you are actually installing. This is a great improvement over the previous version present in Ubuntu 13.10, but it would be nice if more features were available, like a changelog for the new version of an app." -Softpedia
