What’s New in Ubuntu 15.10 Beta 1?
The array of changes put forward by the Ubuntu family differs dramatically between releases.
Kubuntu 15.10 Beta 1 features the biggest set of changes. It offers the shiny new Plasma 5.4 desktop as default (see our earlier post for more on what that brings) and offers the latest KDE Applications 15.08 suite.
Ubuntu GNOME 15.10 Beta 1 offers much of the latest GNOME 3.16 stack – enjoy it while it’s current, as 3.18 is on the way!. You get GNOME-Shell 3.16, a stack of GNOME 3.16 applications, a new GNOME getting started guide and GNOME Photos installed by default (Shotwell remains available).
Lubuntu 15.10 Beta 1 sees only minimal bug fixes applied. Once again, all development effort is focused on getting the new LxQt desktop ship-shape in time for its tentative use as Lubuntu default in October 2016.
Xubuntu 15.10 Beta 1 swaps hardy office stalwart Abiword with LibreOffice Writer, something some have long considered overdue. It also ships updates for a sizeable set of the default Xubuntu app stack, including new versions of gMusicBrowser, LightDM-GTK-Greeter and the nimble Thunar file manager.
Finally, Ubuntu MATE 15.10 Beta 1 bumps the MATE desktop to version 1.10 (“mostly”), offers a refreshed MATE welcome tool, a new version of the helpful MATE Tweak Tool and integrates Deja Dup backup into the Caja file manager.
Beta = bugs
Ubuntu 的 Beta 版本不太适合作为你的默认操作系统，因为它有可能有些 bug，破损等潜在问题。
Ubuntu 15.10 最终版本将会在2015年10月22日发布。
