First of these is a mass upgrade of the GNOME Stack to the latest upstream release, GNOME 3.26.1, which introduces all the bug fixes and improvements to make the GNOME 3.26 desktop environment a reliable, mature, secure, and safe place for use in production environments. A second point release, GNOME 3.26.2, will be available after the release of Ubuntu 17.10 on October 19, 2017. As you are aware, Ubuntu 17.10 is the first release of the popular and free GNU/Linux operating system in seven years to ship with the GNOME desktop environment by default as Canonical dropped development of its Unity user interface. Thus, the Ubuntu Desktop team needed to adapt to the GNOME philosophy and tried to drop many of the patches they used on Unity.
