Yep, the moment I got word that Linux Mint dropped their Sylvia ISO onto their Download Servers, under the "Stable" folder, I started working on the seamless update from the ISO's base of Mint Sonya, to the new base of Mint Sylvia (18.2 => 18.3). To be honest, for a first try at doing this (all previous Mint Updates came as feren OS Releases), the update process is seamless, and very easy.
How to Update the base:
Also, the hype, feren OS is nearly at 100,000 Total Downloads! Let's see how quick we make it to that mark, shall we? https://sourceforge.net/projects/ferenoslinux/files/stats/timeline?dates=2015-01-23+to+2018-11-30
It's great making something for the community that might become quite big and remain for a very long time to continue serving the community and helping Linux as a result.
