Ubuntu Oneiric Ocelot is the new Ubuntu version for October 2011.
Ubuntu 11.10 continues the renovation of Ubuntu desktop by making Unity to be the only interface available by default. This is possible thanks the inclusion of Unity 2D, the Unity version without graphic effects.
GNOME 3 will be present in this Ubuntu version and you’ll be able to install GNOME Shell from the official repositories.
Furthermore, Ubuntu Oneiric includes new programs such as Thunderbird – instead of evolution- or Deja Dup – an useful backup application.
Making this version lighter is the other goal of Ubuntu developers. PiTiVi and Synaptic leave Ubuntu due to this reason, although you’ll be able to install them accessing the official repositories.
LightDM will be the one in charge of showing the start session screen, which can be modified.
Ubuntu 11.10 keeps getting better and better and is still the most wanted GNU / Linux distribution.
