Rilasciata Ubuntu 18.04 “Bionic Beaver! insieme a tutte le derivate ufficiali: Ubuntu Studio, Xubuntu, Kubuntu, Ubuntu MATE, Ubuntu Budgie.
L’ultima versione di Ubuntu utilizza nella fattispecie GNOME 3.28, e implementa diverse ulteriori novità: vengono dismessi i pacchetti di installazione a 32-bit per la versione desktop (anche questa novità è mutuata da Ubuntu 17.10), e da questa versione Canonical inizierà a raccogliere dati sull’uso del sistema, fra cui la versione del sistema operativo installata, il produttore del dispositivo, il modello della CPU, l’ambiente desktop usato, il fuso orario e i pacchetti installati.
La raccolta dei dati è attiva di default, ma gli utenti possono naturalmente decidere di disabilitarla in favore di una maggiore privacy. Le informazioni raccolte, tuttavia, non sono sufficienti per collegare i dati ad uno specifico dispositivo, e l’intero database sarà disponibile pubblicamente. Fra le novità ci sarà naturalmente l’ultimo Kernel Linux (4.15), un processo di avvio velocizzato, e l’opzione per installare una versione alleggerita del sistema operativo.
In questa troveremo solo il browser web, Mozilla Firefox, e i tool di base. Il display server di default torna ad essere Xorg, dopo che su Ubuntu 17.10 era stato sostituito con Wayland (che a sua volta può essere attivato a posteriori sulla 18.04 LTS). Le emoji sono adesso riportate a colori e alcune delle app native vengono installate come Snap sulle installazioni pulite.
Ubuntu 18.04 LTS sarà supportato fino ad aprile 2023, mentre le ultime due versioni attualmente supportate (14.04 e 16.04) verranno aggiornate rispettivamente fino ad aprile 2019 e aprile 2021. Per chi invece utilizza la versione 17.10 non-LTS, il supporto finirà a luglio 2018 e l’aggiornamento alla più recente versione LTS è caldamente consigliato. Il download di Ubuntu 18.04 LTS può essere effettuato sul sito ufficiale, dove possono essere scaricate le immagini ISO.
Chi invece utilizza un sistema Ubuntu 16.04 LTS o 17.10 riceverà una notifica all’interno del sistema operativo attraverso la quale effettuare l’aggiornamento

The Ubuntu Studio team has published version 18.04 of their distribution. While Ubuntu Studio shares packages with Ubuntu 18.04 LTS, this release is not a long term support (LTS) version and offers support for nine months. The distribution’s release announcement states: “We are happy to announce the release of our latest version, Ubuntu Studio 18.04 Bionic Beaver! Unlike the other Ubuntu flavors, this release of Ubuntu Studio is not a Long-Term Support (LTS) release. As a regular release, it will be supported for 9 months. Although it is not a Long-Term Support release, it is still based on Ubuntu 18.04 LTS which means the components will be supported as usual for a LTS release. Since it’s just out, you may experience some issues, so you might want to wait a bit before upgrading. Please see the release notes for a complete list of changes and known issues.” Further details can be found in the project’s release notes.

Under the hood, there have been updates to many core packages, including a new 4.15-based kernel, KDE Frameworks 5.44, Plasma 5.12 LTS and KDE Applications 17.12.3. We’ve made some notable changes since 16.04 LTS. VLC is the default media player and Cantata Qt5 the default music player.

David Mohammed has announced the release of Ubuntu Budgie 18.04, a desktop Linux distribution featuring the refreshingly simple Budgie desktop that aims to provide a “familiar, modern and functional experience”: “We are pleased to announce the release of a new version of our distribution, the third as an official flavor of the Ubuntu family and our very first LTS. The LTS version is supported for 3 years while the regular releases are supported for 9 months. Based on 17.10 experiences, feedback and suggestions we have received from our users, the new release comes with a lot of new features, fixes and optimizations. Here is what you can expect with the new release: more customisation options via Budgie Welcome; lots more Budgie applets available to be installed; dynamic workspaces, hot-corners and Window shuffler; brand-new GTK+ theme called Pocillo; new applets as standard in the panel or available to be added via Budgie Settings.” Here is the short release announcement with links to much more detailed release notes and screenshots.

Martin Wimpress has announced the release of Ubuntu MATE 18.04, the latest version of the popular Ubuntu variant featuring the MATE desktop environment. This new version comes with the new MATE 1.20.1: “The MATE Desktop has transitioned from the GTK+ 2.24-based MATE 1.12 to the very latest MATE 1.20.1 based on GTK+ 3.22. This migration has been several years in the making, and most of 2016 and 2017 was spent refining the GTK+ 3 implementation. The move to GTK+ 3 has made it possible to introduce many of the new features you’ll read about below. Support for libinput has been added and is now the default input handler for mouse and touchpad, which has resulted in much improved responsiveness and support for multi-finger touch gestures. Thanks to our friends at Hypra.fr, accessibility support (particularly for visually impaired users) has seen continued development and improvement. MATE Desktop is proud to provide visually impaired users the most accessible open-source desktop environment. MATE Desktop 1.20 supports HiDPI displays and if you have one then Ubuntu MATE will automatically enable pixel scaling, presenting you with a super crisp desktop and applications.” See the detailed release announcement for further information and screenshots.
