Appendix C - Features in older releases

New features for Debian Edu 9+edu0 Codename Stretch released 2017-06-17

Installation changes

  • New version of debian-installer from Debian Stretch, see its installation manual for more details.

  • The "Thin-Client-Server" profile has been renamed to "LTSP-Server" profile.
  • New artwork based on the "soft Waves" theme, the default artwork for Debian 9 Stretch.

Software updates

  • Everything which was new in Debian 9 Stretch, eg:
    • Linux kernel 4.9
    • Desktop environments KDE Plasma Workspace 5.8, GNOME 3.22, Xfce 4.12, LXDE 0.99.2, MATE 1.16
      • KDE Plasma Workspace is installed by default; to choose one of the others see this manual.
    • Firefox 45.9 ESR and Chromium 59
      • Iceweasel has been re-renamed to Firefox! :-)

    • Icedove has been re-renamed to Thunderbird and is now installed by default.
    • LibreOffice 5.2.6

    • Educational toolbox GCompris 15.10
    • Music creator Rosegarden 16.06
    • GOsa 2.7.4
    • LTSP 5.5.9
    • Debian Stretch includes more than 50000 packages available for installation.

Documentation and translation updates

  • Translation updates for the templates used in the installer. These templates are now available in 29 languages.
  • The Debian Edu Stretch Manual is fully translated to German, French, Italian, Danish, Dutch, Norwegian Bokmål and Japanese. The Japanese translation was newly added for Stretch.
    • Partly translated versions exist for Spanish, Polish and Simplified Chinese.

Other changes compared to the previous release

  • Icinga replaces Nagios as monitoring tool.
  • kde-spectacle replaces ksnapshot as screenshot tool.
  • The free flash player gnash is back again.
  • Plymouth is installed and activated by default, except for the 'Main Server' and 'Minimal' profiles; pressing ESC allows to view boot and shutdown messages.
  • Upon upgrade from Jessie the LDAP data base has to be adjusted. The sudoHost value 'tjener' has to be replaced with 'tjener.intern' using GOsa² or an LDAP editor.
  • The 32-bit PC support (known as the Debian architecture i386) now no longer covers a plain i586 processor. The new baseline is the i686, although some i586 processors (e.g. the "AMD Geode") will remain supported.
  • Debian 9 enables unattended upgrades (for security updates) by default for new installations. This might cause a delay of about 15 minutes if a system with a low uptime value is powered off.
  • LTSP now uses NBD instead of NFS for the root filesystem. After each single change to an LTSP chroot, the related NBD image must be regenerated (ltsp-update-image) for the changes to take effect.

  • Concurrent logins of the same user on LTSP server and LTSP thin client are no longer allowed.

New features for Debian Edu 8+edu0 Codename Jessie released 2016-07-02

Installation changes

Software updates

  • Everything which is new in Debian 8 Jessie, eg:
    • Linux kernel 3.16.x
    • Desktop environments KDE Plasma Workspace 4.11.13, GNOME 3.14, Xfce 4.10, LXDE 0.5.6
      • new optional desktop environment: MATE 1.8
      • KDE Plasma Workspace is installed by default; to choose one of the others see this manual.
    • the browsers Iceweasel 31 ESR and Chromium 41
    • LibreOffice 4.3.3

    • Educational toolbox GCompris 14.12
    • Music creator Rosegarden 14.02
    • GOsa 2.7.4
    • LTSP 5.5.4
    • new boot framework: systemd. More information is available in the Debian systemd wiki page and in thesystemd manual.

    • Debian Jessie includes about 42000 packages available for installation.

Documentation and translation updates

  • Translation updates for the templates used in the installer. These templates are now available in 29 languages.
  • Two manual translations have been completed: Dutch and Norwegian Bokmål.
  • The Debian Edu Jessie Manual is fully translated to German, French, Italian, Danish, Dutch and Norwegian Bokmål. A partly translated version exists for Spanish.

Other changes compared to the previous release

  • squid: Shutdown and reboot of the main server takes longer than before due to a new default setting shutdown_lifetime 30 seconds. As an example the delay could be set to 10 seconds by appending the line shutdown_lifetime 10 seconds to /etc/squid3/squid.conf.

  • ssh: The root user is no longer allowed to login via SSH with password. The old default PermitRootLogin yes has been replaced with PermitRootLogin without-password, so ssh-keys will still work.

  • slbackup-php: To be able to use the slbackup-php site (which uses root logins via ssh), PermitRootLogin yes has to be set temporarily in /etc/ssh/sshd_config.

  • sugar: As the Sugar desktop was removed from Debian Jessie, it is also not available in Debian Edu jessie.

New features in Debian Edu 7.1+edu0 Codename Wheezy released 2013-09-28

User visible changes

  • Updated artwork and new Debian Edu / Skolelinux logo, visible during installation, in the login screen and as desktop wallpaper.

Installation changes

  • New version of debian-installer from Debian Wheezy, see installation manual for more details.

  • The DVD image was dropped, instead we added a USB flash drive / Blu-ray disc image, which behaves like the DVD image, but is too big to fit on a DVD.

Software updates

  • Everything which is new in Debian Wheezy 7.1, eg:
    • Linux kernel 3.2.x
    • Desktop environments KDE "Plasma" 4.8.4, GNOME 3.4, Xfce 4.8.6, and LXDE 0.5.5 (KDE "Plasma" is installed by default; to choose GNOME, Xfce or LXDE: see manual.)
    • Web browser Iceweasel 17 ESR
    • LibreOffice 3.5.4

    • LTSP 5.4.2
    • GOsa 2.7.4
    • CUPS print system 1.5.3

    • Scratch visual programming environment 1.4.0.6
    • New version of debian-installer from Debian Wheezy, see installation manual for more details.

    • Debian Wheezy includes about 37000 packages available for installation.

Documentation and translation updates

  • The Debian Edu Wheezy Manual is fully translated to German, French, Italian and Danish. Partly translated versions exist for Norwegian Bokmål and Spanish.

  • Slight changes to some objects and acls to have more types to choose from when adding systems in GOsa. Now systems can be of type server, workstation, printer, terminal or netdevice.

Other changes

  • New Xfce desktop task.
  • LTSP diskless workstations run without any configuration.
  • On the dedicated client network of LTSP servers (default 192.168.0.0/24), machines run by default as diskless workstations if they are powerful enough.
  • GOsa gui: Now some options that seemed to be available, but are non functional, are greyed out (or are not clickable). Some tabs are completely hidden to the end user, others even to the GOsa admin.

Known issues

  • Using KDE "Plasma" on standalone and roaming workstations, at least Konqueror, Chromium and Step sometimes fail to work out-of-the box when the machines are used outside the backbone network, proxy use is required to use the other network but no wpad.dat information is found. Workaround: Use Iceweasel or configure the proxy manually.
