Paolo Besser released an emergency patch for the latest Icaros Desktop version 1.5.1 due to a severe issue with the FAT-handler that could cause issues for people using FAT12 or FAT16 formattted devices.
In short this patch includes a new fixed FAT handler.
Because of the critical nature of this issue Paolo decided to release this patch as a seperate download, as well as updated all the complete distributions that he provides on his download-page.
This means that new users of Icaros Desktop should download the newest (and patched) version of Icaros Desktop 1.5.1 (also called Icaros Desktop 1.5.1-1) while people that already have installed the Icaros Desktop 1.5 (also Legacy Kernel Edition) or Icaros Desktop 1.5.1 should run this mandatory patch 01 as soon as possible (you can stay with Icaros Desktop version 1.5 if you want but patch 01 is mandatory).
To make it more convenient Paolo also released a patched 1.5.1 update package (to upgrade your existing Icaros Desktop 1.5 installation to version 1.5.1) which already includes patch 01. Please note that 1.5 LKE cannot be updated to 1.5.1 due to technical differences in the kernels
