Announcing NetBSD 6.1

Introduction

The NetBSD Project is pleased to announce NetBSD 6.1, the first feature update of the NetBSD 6 release branch. It represents a selected subset of fixes deemed important for security or stability reasons, as well as new features and enhancements.

Please note that all fixes in the prior security/bugfix updates (NetBSD 6.0.1 and 6.0.2) are also in 6.1. Please see the release map graph on the NetBSD website for a visual representation of the relationship between releases.

Complete source and binaries for NetBSD 6.1 are available for download at many sites around the world. A list of download sites providing FTP, AnonCVS, SUP, and other services may be found at http://www.NetBSD.org/mirrors/. We encourage users who wish to install via ISO or USB disk images to download via BitTorrent by using the torrent files supplied in the images area. A list of hashes for the NetBSD 6.1 distribution has been signed with the well-connected PGP key for the NetBSD Security Officer: ftp://ftp.NetBSD.org/pub/NetBSD/security/hashes/NetBSD-6.1_hashes.asc

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. More extensive information on NetBSD is available from our website:

Fund Drive

Your donations to the NetBSD Foundation have allowed the project to make major improvements to the code base. With the release of NetBSD 6.1, we would like to continue funded development in various areas, including:

  • Improving network stack concurrency and performance.
  • Development of modern file systems and improvement of existing ones.
  • Features which are useful in embedded environments, such as high resolution timers and execute in place (XIP) support.
  • Automatic testing and quality assurance.

About NetBSD

NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices. Its clean design and advanced features make it excellent for use in both production and research environments, and the source code is freely available under a business-friendly license. NetBSD is developed and supported by a large and vibrant international community. Many applications are readily available through pkgsrc, the NetBSD Packages Collection.

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 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 to help with ongoing upgrades and maintenance, as well as with operating expenses for the NetBSD Foundation.
