Arch Linux 2016.03.01 has been released few days ago. It ships with Linux Kernel 4.4 LTS branch, and many updated packages, bug fixes.

Upgrade to Arch Linux 2016.03.01 from older version

As you probably know, Arch Linux is a rolling release distribution like Gentoo. That means, there are no major release versions like in other Linux distributions such as Ubuntu, Debian, RHEL, SUSE. Say for example, the latest release of Ubuntu distribution is Ubuntu 16.04 LTS. But in Arch Linux, there is no such kind of release version. Arch Linux packages are constantly being updated. All you have to do is to update and upgrade Arch Linux from time to time in-order to use most recent Arch Linux version.

Unlike other Linux distributions, Arch Linux upgrade method is very simple.

Warning: Before upgrading your Arch Linux, first you must read the latest Arch News to find out if there are any major software or configuration changes with the latest packages. Before upgrading fundamental software (such as the kernel, xorg, systemd, or glibc) to a new version, look over the appropriate forum to see if there have been any reported problems.

First, backup all important files.

Then, run the following command to update Arch Linux repositories, and upgrade to Arch Linux 2016.03.01 from any older version.

# pacman -Syu
