Ubuntu 14.04 LTS Beta (Trusty Tahr) Officially Released
Let's start with the Linux kernel. Canonical will release Ubuntu 14.04 LTS with Linux kernel 3.13, which is now the most advanced kernel in existence. That will probably change the in course of the next week, but 3.13 remains a very good Linux kernel to have. As usual, the developers won't actually ship the official kernel, but their own version that is based on that branch.
