SysLinuxOS 12.1 brings some improvements and bug fixes. By default, it includes the latest kernel 6.4 directly from the backports repository, replacing the removed 6.3.8 version. Additionally, VMware Player 17 has been added. Other changes relate to some system icons, and further adjustments have been made in preparation for the upcoming integration of new custom repositories for SysLinuxOS. The changes apply to both versions, Gnome and Mate.
