Announcing NetBSD 4.0.1

The NetBSD Project is pleased to announce that update 4.0.1 of the NetBSD operating system is now available. NetBSD 4.0.1 is the first security/critical update of the NetBSD 4.0 release branch. This represents a selected subset of fixes deemed critical in nature for stability or security reasons, no new features have been added.

NetBSD 4.0.1 runs on 54 different system architectures featuring 17 machine architectures across 17 distinct CPU families, and is being ported to more. The NetBSD 4.0.1 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 4.0.1 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. A list of hashes for the NetBSD 4.0.1 distribution has been signed with the well-connected PGP key for the NetBSD Security Officer: ftp://ftp.NetBSD.org/pub/NetBSD/security/hashes/NetBSD-4.0.1_hashes.asc

Please note that all fixes in security/critical updates (i.e., NetBSD 4.0.1, 4.0.2, etc) are cumulative, so the latest update contains all such fixes since the corresponding minor release. These fixes will also appear in future minor releases (i.e., NetBSD 4.1, 4.2, etc), together with other less-critical fixes and feature enhancements.

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 website. Commercial support is available from a variety of sources; some are listed at http://www.NetBSD.org/gallery/consultants.html. More extensive information on NetBSD is available from our website:

The NetBSD Foundation would like to thank all those who have contributed code, hardware, documentation, funds, colocation for our servers, web pages and other documentation, release engineering, and other resources over the years. More information on the people who make NetBSD happen is available at:

We would like to especially thank the University of California at Berkeley and the GNU Project for particularly large subsets of code that we use. We would also like to thank the Internet Systems Consortium Inc., the Network Security Lab at Columbia University's Computer Science Department, and Ludd (Luleå Academic Computer Society) computer society at Luleå University of Technology for current colocation services.

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 welcome assistance with ongoing upgrades and maintenance, as well as with operating expenses for The NetBSD Foundation.

Donations can be done via PayPal to <[email protected]> and are fully tax-deductible in the US. If you would prefer not to use PayPal, or would like to make other arrangements, please contact <[email protected]>.
