Hello Linux Geeksters. After the latest update, Ubuntu 14.04 LTS has switched to Kernel 3.12.4, as default.
“The master branch for trusty has been rebased to the latest v3.12.4 upstream stable kernel. We also continue to track the latest v3.13 kernel on our unstable branch and most recently rebased to v3.13-rc3. We anticipate uploading a v3.13 based Trusty kernel to the archive after the new year,” said Canonical’s Joseph Salisbury in the mailing lists.
For now, Ubuntu 14.04 is very similar to Ubuntu 13.10 Saucy Salamander, but changes will be implemented soon. The Ubuntu developers plan to replace GNOME Control Center with Unity Control Center, they may remove the memtest86+ from the packages installed by default on Ubuntu 14.04 Cloud images, and they will update the Nvidia Prime package, enabling the users to easily switch between GPUs, to reduce the battery consumption. More information about this changes can be found here.
As you may know, Ubuntu 14.04 Trusty Tahr will be released on the 14th of April, 2014. Despite the fact that the developments has started only for two months, the daily builds of Ubuntu 14.04 are quite stable.
