Yesterday, April 26, 2018, the release of the next version of Ubuntu - 18.04 Bionic Beaver. Its code name can be translated into Russian as “very strong beaver” (yes, the word bionic has
such a meaning ). Canonical founder Mark Shuttleworth explains the choice of a title like this:
We thus welcome creators - those who create applications and packages, who create Ubuntu, who create something based on Ubuntu. Paying tribute to their tireless work, we chose the beast, famous for its energetic attitude, hardworking kind and engineering savvy, as a mascot.
Ubuntu 18.04 applies to LTS (Long Term Support) versions. They come out every two years (the previous LTS version was 04/16) and are maintained for five years from the date of release.
Today, on the day of the official release, it's time to talk about the innovations implemented in the new version of Ubuntu. And our users can already try everything today in practice: the image of Ubuntu 18.04 is already available for use in all our services: in the
Virtual Private Cloud ,
Vscale Cloud Servers , and in
dedicated servers .
