Announcing NetBSD 2.1

Introduction

   The  NetBSD  Project  is  pleased  to announce that release 2.1 of the
   NetBSD operating system is now available.

About NetBSD 2.1

   NetBSD  2.1  is  the first maintenance release of the netbsd-2 release
   branch.   This  release  provides  numerous  functional  enhancements,
   including support for many new devices, hundreds of bug fixes, patches
   and  updates  to  kernel subsystems, and many enhancements to the user
   environment.  In  addition, all of the security fixes and critical bug
   fixes from the NetBSD 2.0.3 update are included as well.

   Complete source and binaries for NetBSD 2.1 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:

     http://www.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.  BitTorrent  has  recently  been  added  to  the  list of
   distribution  mechanisms  and  its  use is strongly encouraged to help
   keep bandwidth available.

About NetBSD

   The NetBSD operating system is a full-featured, open source, UNIX-like
   operating  system  descended  from  the  Berkeley Networking Release 2
   (Net/2),  4.4BSD-Lite,  and  4.4BSD-Lite2. NetBSD runs on 54 different
   system  architectures  featuring  17  machine  architectures across 17
   distinct  CPU  families,  and  is being ported to more. The NetBSD 2.1
   release  contains  complete  binary  releases for 48 different machine
   types.

   NetBSD  is  a  highly  integrated  system.  In  addition to its highly
   portable,  high  performance kernel, NetBSD features a complete set of
   user  utilities, compilers for several languages, the X Window System,
   firewall  software  and  numerous other tools, all accompanied by full
   source  code.  The  NetBSD  Packages  Collection  contains  over  5500
   packages  and  binary  package  releases for a number of platforms are
   currently in progress.

   More  information  on  the goals of the NetBSD Project can be procured
   from the NetBSD web site at:

     http://www.NetBSD.org/Goals/

   NetBSD is free. All of the code is under non-restrictive licenses, and
   may  be used without paying royalties to anyone. Free support services
   are  available  via our mailing lists and web site. Commercial support
   is available from a variety of sources; some are listed at:

   site:

   NetBSD  is  the  work  of  a diverse group of people spread around the
   world.  The  "Net"  in  our  name  is a tribute to the Internet, which
   enables  us  to  communicate  and  share  code,  and without which the
   project would not exist.

Major Changes Between 2.0 and 2.1

   The  complete  list of changes can be found in the CHANGES-2.1 file in
   the top level directory of the NetBSD 2.1 release tree.

   The following major changes were made between 2.0 and 2.1:

Kernel

     * A longstanding bug in the SYSV semaphore code has been fixed.
     * Eliminated hangs when large processes fork.
     * ata(4)  and  wdc(4)  drives now only downgrade modes due to actual
       CRC errors, and UDMA modes are downgraded more slowly.

       SATA150 series of controllers, including RAID support.
     * The RAIDframe disk driver had various bugfixes and improvements.

       structures.   The   atactl  smart  status  command  now  works  on
       big-endian hosts.

Networking

About the NetBSD Foundation

   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  organisation 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
