Ubuntu 19.04, codenamed Disco Dingo, was released on 18 April 2019. It incorporates the Linux kernel version 5.0, which adds support for AMD FreeSync technology for liquid-crystal displays, Raspberry Pi touchscreens, Adiantum encryption, Btrfs swap files as well as many USB 3.2 and Type-C improvements and several new hardware. Ubuntu 19.04 uses GNOME Shell Desktop 3.32, which includes a new icon set, increased performance, smoother animations, night-light intensity control and advanced application permissions. The updated Nautilus 3.32 file manager now supports favoriting files. A new header bar, as well as 'find' and 'read only' modes have been added to the default terminal emulator. Version 19 of the open-source graphics drivers Mesa is also natively available in this version of Ubuntu. Furthermore, the Grub menu now allows a 'safe graphics' mode, in case of issues with graphics cards or graphics drivers. This option will boot Ubuntu with "NOMODESET" turned on and will allow the installation any proprietary drivers needed by the system. Geoclue integration and fractional scaling in the GNOME Shell for HiDPI displays (currently available only in Wayland sessions and experimentally in Xorg sessions) are also included. Improvements for running Ubuntu on a VMWare virtual machine include integration of open-vm-tools within Ubuntu, allowing for bi-directional clipboard and file sharing. Ubuntu Server 19.04 updated QEMU to version 3.1, allowing for creation of a virtual 3D GPU inside QEMU virtual machines. libvirt was updated to version 5.0 and Samba was updated to version 4.10.x. Samba and its dependencies were updated to Python 3, with the exception of tdb, which still builds a Python 2 package, namely python-tdb. Ubuntu Server 19.04 includes the latest OpenStack release, Stein, and has vSwitch version 2.11.
