After almost 24 months of constant development the Debian project is proud to present its new stable version 8 (code name “Jessie”), 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.
“Jessie” ships with a new default init system, systemd. The systemd suite provides many exciting features such as faster boot times, cgroups for services, and the possibility of isolating part of the services. The sysvinit init system is still available in “Jessie”.
The UEFI (“Unified Extensible Firmware Interface”) support introduced in “Wheezy” has also been greatly improved in Jessie. This includes workarounds for many known firmware bugs, support for UEFI on 32-bit systems, and support for 64-bit kernels with 32-bit UEFI firmware (with the latter being included only on our amd64/i386 “multi-arch” installation media).
Since the previous release, members of the Debian project have also made important improvements to our supporting services. One of these is a browsable view of all source code shipped in Debian  currently
available at sources.debian.net . Of course, with over 20,000 source packages, it can be quite daunting to locate the right file. Therefore, we are also very pleased to present Debian Code Search , available at codesearch.debian.net . Both services are complemented by a completely rewritten and more reponsive package tracking system .
