What’s new in Debian 9?
Your NICs are now named using BIOS/firmware and slot. For example ens0 or enp1s1 (Ethernet) or wlp3s0 (WLAN):
The Xorg server no longer requires running as root user. It reduces the risk of privilege escalation via bugs in the X server. Another security feature includes compiling all executables using PIE (“position independent executables”) i.e. ASLR will be turned on by default using GCC 6 compiler for almost all binaries.
Latest software includes:
- LibreOffice 5.2
- Calligra 2.9
- MariaDB (MariaDB replaces Oracle MySQL Server) 10.1
- PHP 7.0
- Python 3.5 (default)
- PostgreSQL 9.6
- Samba 4.5
- Vim 8
- Emacs 25.1
- Exim MTA 4.88
- GCC 6.3

Debian 9 CD ISO download
There are total 3 ISO images, I strongly suggest to get DVD images:
To grab the netinst CD here a wget command (it is a small CD image that contains just the core Debian installer code and a small core set of text-mode programs (known as “standard” in Debian). To install a desktop or other common software, you’ll also need either an Internet connection). To grab a 32 bit version:
$ wget -c https://cdimage.debian.org/debian-cd/current/i386/iso-cd/debian-9.0.0-i386-netinst.iso
To get a 64 bit version:
$ wget -c https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-9.0.0-amd64-netinst.iso
To grab the 32 bit version CD ISO with xfce desktop:
$ wget -c https://cdimage.debian.org/debian-cd/current/i386/iso-cd/debian-9.0.0-i386-xfce-CD-1.iso
To grab the 64 bit version CD ISO with xfce desktop:
$ wget -c https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-9.0.0-amd64-xfce-CD-1.iso
