4MLinux 21.0 has been in development since early November 2016, and only now it hit the stable channel, which means that existing 4MLinux 20.0 users can finally upgrade their installations and receive new packages versions, along with all the latest GNU/Linux technologies and a bunch of new exciting features. Among these, there’s out-of-the-box support for Windows shares, thanks to the implementation of the CIFS (Common Internet File System) file system and Samba. Most of the drivers have also been updated for AMD Radeon and Nvidia GPUs, as well as Broadcom wireless adapters.
