Ubuntu 12.04.3 LTS has been released by Canonical and now it’s time to see if anything has changed from the previous point release with the help of a short screenshot tour.
A number of major changes have been introduced in this latest version of Ubuntu 12.04 (Precise Pangolin). For example, Nautilus quicklist support has been added to Unity launcher, clickPad devices are trackpads where the physical button is integrated into the trackpad surface, System Settings has several new "options" to customize Unity's look and behavior, and much more.
Also, the default music player is now Rhythmbox, LibreOffice has been updated to 3.5.4, and GNOME to version 3.4.2.
User who already have the previous point release installed won’t have to do anything special, and users of Ubuntu 11.10 and Ubuntu 10.04 can upgrade directly to the new version.
