After around 25 months of development, Debian has now released the next stable version Debian 10 "Buster" which will be supported for five years. In this release GNOME now defaults to using Wayland instead of Xorg, the AppArmor kernel security module is enabled by default and it's powered by the Linux 4.19 kernel.
For those who don't like to live on the edge, Debian is a good choice for having a solid computing experience with Linux. Debian 10 comes with these available desktops:
- Cinnamon 3.8
- GNOME 3.30
- KDE Plasma 5.14
- LXDE 0.99.2
- LXQt 0.14
- MATE 1.20
- Xfce 4.12
Like other distributions, you don't need to install Debian right away. It has a "live" image you can stick on a USB, to test it without making any changes on your computer.
For those unaware, Debian is what both Ubuntu (so also Mint, elementary OS, KDE neon and many more) and SteamOS base themselves upon, so the work that goes into Debian affects a great many other distributions.
If you're not upgrading right away, rest assured that Debian 9 "Stretch" is still supported and will continue to be for 12 months with the Debian Security Team, after which it will be handed over to the Debian LTS team.
