This version of the desktop is based on Debian Jessie(8).
Some of you will be aware that a new stable version of Debian (called Stretch)
was released last week.
 Rest assured – we have been working on porting everything across to Stretch for some time now, and we will have a Stretch release ready some time over the summer.

Highlights of this Raspbian OS update include:

- A custom Bluetooth plugin for the LXDE panel to make it easy to manage Bluetooth devices on the Pi 3, since none of the existing plugins were deemed effective for Raspbian purposes. ( It removes the need to use sudo in programs which want to access the GPIOs )

- Bluetooth audio is now supported.

- There is a SD card copier GUI program to make backups easier.

- The pigpio library was added for making it easier to deal with the Raspberry Pi GPIO pins from C, Python, and other programming languages.

- The Geany text editor is now bundled with Raspbian.

- Various other application updates.

- The used kernel is now derived from Linux 4.4.

- Other tweaks and fixes.

 When flashing a new Raspbian image, the file system will automatically be expanded to use all the space on the card when it is first booted.

SAUF qu'on est  en Debian Wheezy (7) et non Jessie (8) ...

    Accès aux ports du GPIO sans passer par sudo
    Amélioration de l’interface utilisateur, y compris le remplacement de raspi-config par une version graphique qui devrait rassurer les débutants.
    Deux nouveaux environnements de programmation Java
    L’installation en standard de LibreOffice (pour le meilleur et pour le pire 😉 )

(on peut mettre à jour depuis Wheezy mais bon mieux vaut sauvegarder avant)
