Canonical has just announced its 26th distribution of Ubuntu called Zesty Zapus. The 17.04 version is still using the Unity desktop and brings several improvements to the Linux experience, but since it is non-LTS (Long-Term Support), it will be supported for only nine months.
The new version brings improved printer support and the option to run the Unity 8 desktop environment. Under the hood is the Linux 4.10 kernel, meaning it supports the AMD Ryzen and Intel Kaby Lake processors. Other notable changes include the use of a swap file for new install and updates to various included apps.
