Versie 9.0 van Debian GNU/Linux is uitgekomen. Debian is een opensource-besturingssysteem, dat zowel voor desktops als servers gebruikt kan worden en waarbij de nadruk op stabiliteit en veiligheid ligt. Het wordt dan ook als basis voor diverse Linux-distributies gebruikt, waaronder Ubuntu en Linux Mint. Versie 9.0, die als codenaam 'Stretch' meegekregen heeft, is een zogenaamde Long Term Support-uitgave en zal de komende vijf jaar van updates worden voorzien. In versie 9 is MySQL vervangen door MariaDB en zien we ook de terugkeer van Firefox en Thunderbird. Andere belangrijke updates zijn KDE van 4 naar 5, de Linux kernel van 3.16 naar 4.9, LibreOffice van 4.3 naar 5.2 en QT van 4.8 naar 5.7.
Debian 9StretchreleasedAfter 26 months of development the Debian project is proud to present its new stable version 9 (code name
Stretch), which will be supported for the next 5 years thanks to the combined work of the Debian Security team and of the Debian Long Term Support team.Debian 9 is dedicated to the project's founder Ian Murdock, who passed away on 28 December 2015.
In
Stretch, the default MySQL variant is now MariaDB. The replacement of packages for MySQL 5.5 or 5.6 by the MariaDB 10.1 variant will happen automatically upon upgrade.Firefox and Thunderbird return to Debian with the release of
Stretch, and replace their debranded versions Iceweasel and Icedove, which were present in the archive for more than 10 years.Thanks to the Reproducible Builds project, over 90% of the source packages included in Debian 9 will build bit-for-bit identical binary packages. This is an important verification feature which protects users from malicious attempts to tamper with compilers and build networks. Future Debian releases will include tools and metadata so that end-users can validate the provenance of packages within the archive.
Administrators and those in security-sensitive environments can be comforted in the knowledge that the X display system no longer requires
rootprivileges to run.The
Stretchrelease is the first version of Debian to feature themodernbranch of GnuPG in thegnupgpackage. This brings with it elliptic curve cryptography, better defaults, a more modular architecture, and improved smartcard support. We will continue to supply theclassicbranch of GnuPG as gnupg1 for people who need it, but it is now deprecated.Debug packages are easier to obtain and use in Debian 9
Stretch. A newdbg-symrepository can be added to the APT source list to provide debug symbols automatically for many packages.The UEFI (
Unified Extensible Firmware Interface) support first introduced inWheezycontinues to be greatly improved inStretch, and also supports installing on 32-bit UEFI firmware with a 64-bit kernel. The Debian live images now include support for UEFI booting as a new feature, too.
