Updated Linux Distributions

SME Server (known as e-smith at the time) was founded in January 1999 by Joseph and Kim Morrison. The company introduced the first version of its flagship software product, the e-smith server and gateway, in April 1999. By the end of the year, many thousands of e-smith servers were running in countries from Fiji to Finland. Word was spreading quickly among developers and systems integrators who needed a solid, easy-to-use server for their small-business customers. In July 2001, e-smith was acquired by Mitel Networks, but was later released as an open-source product under the GPL licence. In May 2013 a new not-for-profit organisation was set up to manage SME server. Due to copyright issues it was named Koozali SME Server Inc. The word "Koozali" approximates to Swahili for "rebirth". Future versions will use this name. The distribution, which is based on CentOS, is currently entirely funded by donations.

AnduinOS is an Ubuntu-based distribution which provides a GNOME desktop which has been themed and styled to resemble Windows 11.

KaOS is a desktop Linux distribution that features the latest version of the KDE desktop environment, the Calligra office suite, and other popular software applications that use the Qt toolkit.

TUXEDO OS is an Ubuntu-based distribution developed in Germany by TUXEDO Computers GmbH, designed and optimised for the company's own range of Linux-friendly personal computers and notebooks.
