Ubuntu MATE 16.04.1 LTS is not a major release, and if your Ubuntu MATE 16.04 LTS (Xenial Xerus) installation is up to date, you already have the latest software updates and security patches that have been injected in the new installation mediums generated mainly for those who want to reinstall or deploy the OS on new systems. There are, however, some small changes to various of the in-house built tools. For example, Ubuntu MATE Welcome has been updated with a working partition resizer when deploying Ubuntu MATE on Raspberry Pi single-board computers and removal of the linux-firmware-nonfree package.
