Hello Linux Geeksters. As you may know, the development for Ubuntu 14.04 Trusty Tahr has just started three weeks ago, short time after the release on Ubuntu 13.10 Saucy Salamander.
Some Canonical developers have revealed which packages will be updated for sure (among others): GLib to GLib 2.40, an updated WebKit, GTK 3.8 which will be set as default, despite the fact that many Ubuntu enthusiasts would prefer GTK 3.10.
As I have written here, Ubuntu 14.04 Trusty Tahr will be using Gnome 3.8 as default, since it will be a LTS distribution and Gnome 3.8 has been already fixed and patched for Ubuntu Saucy. Despite this, Canonical will adopt the Gnome-Style apps, a bunch of apps created by the Gnome developers with a new interface, integrating the title bar in the toolbar.
For now, the new apps don’t work well with non gnome-shell environments, so they have to work hard in order to integrate the Gnome-Style apps in Unity.
But let’s not forget about Mir. Since Mark Shuttleworth’s aim is to create a full convergence between the Ubuntu mobile and desktop versions, with the arrival of Ubuntu 14.04, Canonical has to make Mir stable enough, in order to be used as the default display server for Ubuntu 14.04 Trusty Tahr desktop and mobile.
Also, the Ubuntu team intends to hire a technical lead on the Mir developers, in order to guide the Mir coders. The requirements for the Mir leader is to have the following skills (among others): expertise in mobile graphics stacks, strong experience in desktop graphics stacks, the ability to design and develop code in C++, experience with OpenGL, OpenGLES, window management.
