In the days of Woody (3.0), we started producing DVDs reliably for every release from r5 onwards. Later releases included both CDs and DVDs as a matter of course.
Starting with Etch (4.0), we started making multi-architecture CDs/DVDs which would boot and allow for installation on more than one type of computer.
Starting with Lenny (5.0), we added Blu-ray (BD) images, downloadable only in jigdo format for the sake of mirror space and bandwidth. We also regularly produced live images - bootable images that run completely from the CD/DVD/USB stick and do not need to be installed to your hard disk. (More details…)
Starting with Squeeze (6.0), we started building CDs and DVDs for kfreebsd-amd64 and kfreebsd-i386, marking the first released non-Linux port of Debian.
