Geert Hendrickx announced the availability of the official release of NetBSD 4.0 Download ISO images for a variety of architectures are available from the NetBSD mirrors i386 CD image: i386cd-4.0.iso (242MB, MD5) x86_64 CD image amd64cd-4.0.iso (166MB, MD5) Torrent files are available here.

   The  NetBSD  Project  is  pleased  to announce that release 4.0 of the NetBSD  operating  system  is now available. NetBSD is a free, secure,and  highly  portable Unix-like Open Source operating system available for  many  platforms, from 64-bit Opteron machines and desktop systems to  handheld  and  embedded  devices.  Its  clean  design and advanced features   make   it   excellent   in  both  production  and  research environments,  and  it  is  user-supported  with complete source. Many   applications  are easily available through pkgsrc, the NetBSD Packages Collection.

   Major  achievements in NetBSD 4.0 include support for version 3 of the Xen  virtual  machine  monitor, Bluetooth, many new device drivers and embedded  platforms based  on ARM, PowerPC and MIPS CPUs. New network services  include  iSCSI target (server) code and an implementation of the  Common  Address  Redundancy  Protocol.  Also, system security was further  enhanced  with  restrictions  of  mprotect(2)  to enforce W^X policies,  the Kernel Authorization framework, and improvements of the Veriexec  file  integrity  subsystem,  which can be used to harden the system  against trojan horses and virus attacks. Please read below for a list of changes in NetBSD 4.0.

   NetBSD  4.0  runs  on  54  different system architectures featuring 17 machine  architectures  across  17 distinct CPU families, and is being ported  to  more.  The NetBSD  4.0  release  contains complete binary releases  for 51 different machine types, with the platforms amigappc, bebox  and  ews4800mips  released in source form only. Complete source and  binaries  for NetBSD 4.0 are available for download at many sites around  the  world.  A  list of download sites providing FTP, AnonCVS,   SUP,  and  other services is provided at the end of this announcement; the  latest  list  of  available  download  sites may also be found at NetBSD.org/mirrors/. We encourage users who wish to install via a CD-ROM ISO image to download via BitTorrent by using the torrent files  supplied in the ISO image area.

Dedication

NetBSD  4.0  is dedicated to the memory of Jun-Ichiro "itojun" Hagino, who  died  in  October  2007. Itojun was a member of the KAME project,which  provided  IPv6  and IPsec support; he was also a member of the NetBSD  core  team (the technical management for the project), and one of  the  Security  Officers.  Due  to Itojun's efforts, NetBSD was the first  open  source  operating  system  with  a  production ready IPv6 networking  stack,  which  was included in the base system before many people  knew  what  IPv6 was. We are grateful to have known and worked with  Itojun,  and  we  know  that  he will be missed. This release is therefore dedicated, with thanks, to his memory.

   Kernel  interfaces  have  continued to be refined, and more subsystems and  device drivers are shared among the different ports. You can look for this trend to continue.

Security

     * The  FAST_IPSEC  IPsec implementation was extended to use hardware acceleration  for  IPv6,  in  addition to the hardware accelerated IPv4  that  was  available  before.  See  fast_ipsec(4)  for  more information.
     * mprotect(2)  got  restrictions  to enforce W^X policies, from PaX. See options(4), sysctl(3), and paxctl(1).
     * GCC 4's support for stack smashing protection (SSP) was enabled by adding libssp, see security(8).

inheritance control.

   The  NetBSD  Foundation  was  chartered  in  1995,  with  the  task of overseeing  core NetBSD project services, promoting the project within industry  and  the  open  source  community,  and holding intellectual property rights on much of the NetBSD code base. Day-to-day operations of the project are handled by volunteers.

   As  a  non-profit  organization with no commercial backing, The NetBSD Foundation  depends  on donations from its users, and we would like to ask  you  to  consider  making  a donation to the NetBSD Foundation in  support  of  continuing  production of our fine operating system. Your generous  donation  would  be  particularly elcome  assistance  with ongoing  upgrades  and maintenance, as well as with operating expenses for The NetBSD Foundation.
