Ubuntu 20.04 LTS (Focal Fossa) released

Ubuntu Linux 20.04 LTS 'Focal Fossa'


Date: Thu, 23 Apr 2020 18:47:04 +0100
From: Iain Lane <laney@ubuntu.com>
To: ubuntu-announce@lists.ubuntu.com
Cc: ubuntu-release@lists.ubuntu.com
Subject: Ubuntu 20.04 LTS (Focal Fossa) released
Message-ID: <20200423174704.GA648173@nightingale.orangesquash.org.uk>
Content-Type: text/plain; charset="utf-8"

The Ubuntu team is very pleased to announce our eighth long-term support
release, Ubuntu 20.04 LTS for Desktop, Server, Cloud and Core.

Codenamed "Focal Fossa", 20.04 LTS continues Ubuntu's proud tradition
of integrating the latest and greatest open source technologies into a
high-quality, easy-to-use Linux distribution. The team has been hard at
work through this cycle, introducing new features and fixing bugs.

The Ubuntu kernel has been updated to the 5.4 based Linux kernel,
with additional support for Wireguard VPN, AUFS5, and improved support
for IBM, Intel, Raspberry Pi and AMD hardware.

Ubuntu Desktop 20.04 LTS features the latest version of the GNOME
desktop environment, 3.36. Notable changes from 18.04 LTS include
performance improvements, a new lock screen design, and support for
fractional scaling under X11. 20.04 LTS also features a new
look-and-feel: the “Yaru” theme, available in both light and dark
variants.

20.04 LTS also brings support for installing an Ubuntu desktop system on
top of ZFS. The latest version brings performance enhancements and
optional encryption support. Zsys, Ubuntu’s ZFS system tool, provides
automated system and user state saving. Tight integration with GRUB
allows a user to revert to any system state on boot and go back in time
to pave the way to a bulletproof Ubuntu Desktop.

Ubuntu 20.04 LTS includes Python 3.8 as the default version but Python
2.7 is still available in the Ubuntu archive.

Ubuntu Server brings major updates to industry-standard packages
available on private clouds, public clouds, containers or bare metal in
your datacentre. Included are an updated HA/Clustering stack, PHP 7.4,
Ruby 2.7, Postgres 12, MySQL 8 and updated OpenSSH with U2F support for
security.

The newest Ubuntu Budgie, Kubuntu, Lubuntu, Ubuntu Kylin, Ubuntu MATE,
Ubuntu Studio and Xubuntu are also being released today.

More details can be found for these at their individual release notes:

    https://wiki.ubuntu.com/FocalFossa/ReleaseNotes#Official_flavours

Maintenance updates will be provided for 5 years for Ubuntu Desktop,
Ubuntu Server, Ubuntu Cloud and Ubuntu Core. All the remaining flavours
will be supported for 3 years. Additional security support is available
with ESM (Extended Security Maintenance).

Users of Ubuntu 19.10 will be offered an automatic upgrade to 20.04 LTS

automatic upgrade when 20.04.1 LTS is released, which is scheduled for
July 23rd. For further information about upgrading, see:

Updated Debian 9: 9.11 released

The Debian Project                               https://www.debian.org/
Updated Debian 9: 9.11 released                         press@debian.org
September 8th, 2019            https://www.debian.org/News/2019/20190908
------------------------------
------------------------------------------


The Debian project is pleased to announce the eleventh update of its
oldstable distribution Debian 9 (codename "stretch").

This point release is primarily an update to the recently-released 9.10,
in order to resolve a critical problem with the installer that was
discovered during image testing.

Please note that the point release does not constitute a new version of
Debian 9 but only updates some of the packages included. There is no
need to throw away old "stretch" media. After installation, packages can
be upgraded to the current versions using an up-to-date Debian mirror.

Those who frequently install updates from security.debian.org won't have
to update many packages, and most such updates are included in the point
release.

New installation images will be available soon at the regular locations.

Upgrading an existing installation to this revision can be achieved by
pointing the package management system at one of Debian's many HTTP
mirrors. A comprehensive list of mirrors is available at:

https://www.debian.org/mirror/list
