These release notes for Ubuntu 17.04 (Zesty Zapus) provide an overview of the release and document the known issues with Ubuntu 17.04 and its flavors.

Support lifespan

Ubuntu 17.04 will be supported for 9 months until January 2018. If you need Long Term Support, it is recommended you use Ubuntu 16.04 LTS instead.

New features in 17.04

For other changes since 16.04 LTS, see the 16.10 Release Notes.

32-bit PowerPC Support Dropped
Networking - The default DNS resolver is now systemd-resolved.
Swap - For new installs, a swap file will be used instead of a swap partition.

Updated Packages - Linux kernel 4.10: Ubuntu 17.04 is based on the Linux release series 4.10.

Driverless Printing
We now support printers which allow printing without printer-specific drivers. These printers are IPP Everywhere and Apple AirPrint printers, but also some PDF, Postscript, and PCL printers work. This way connecting a printer gets as easy as connecting a USB stick.

Ubuntu Desktop

LibreOffice has been updated to 5.3.

Apps provided by GNOME have been updated to 3.24. Exceptions are the Nautilus file manager (3.20), Terminal (3.20), Evolution (3.22), and Software (3.22).

The Calendar app now has a Week view.

gconf is no longer installed by default since it has long been superseded by gsettings. Note that statistics and preferences for the Aisleriot card games will be reset when upgrading to 17.04.
Unity 8 is available as an alternative session

Ubuntu Server

qemu 2.8

Qemu has been updated to the 2.8 release.

See the Changelog for details.

libvirt 2.5

Libvirt has been updated to version 2.5. See the Changelogs for details.

For administrators worth to consider is that depending on the system setup and huge page size availability the specification of a page size for hugepages in a guest xml can now be mandatory.

LXD 2.12

LXD, now at version 2.12, introduces support for GPU passthrough, including NVidia CUDA. A new storage API has also been added, allowing for the creation of multiple storage pools which can then be used to host containers or independent storage volumes.

And a number of new images have been added, including support for Ubuntu Core 16.

DPDK

Ubuntu 17.04 includes the latest release of DPDK, 16.11.1.

See the Release Notes as well as the stable release announcement for more detail.

As a tech preview DPDK is now also available for ppc64el. This includes the latest improvements made in version 16.11.1 in general, but also further improvements to enable the i40e PMD and vfio-pci scanning on spapr platforms.

WARNING: Upgrading an OpenStack deployment is a non-trivial process and care should be taken to plan and test upgrade procedures which will be specific to each OpenStack deployment.
