      ANNOUNCING Tahoe, the Least-Authority File System, v1.7.1

      The Tahoe-LAFS team is pleased to announce the immediate
      availability of version 1.7.1 of Tahoe-LAFS, an extremely
      reliable distributed storage system.

      Tahoe-LAFS is the first distributed storage system which
      offers "provider-independent security"â€"meaning that not even
      the operators of your storage servers can read or alter your
      data without your consent. Here is the one-page explanation of
      its unique security and fault-tolerance properties:

      http://tahoe-lafs.org/source/tahoe/trunk/docs/about.html

      Tahoe-LAFS v1.7.1 is the successor to v1.7.0, which was
      released June 18, 2010 [1].

      v1.7.1 is a stable minor release which adds several bugfixes
      and improvements in security, forward-compatibility,
      packaging, usability, and portability. See the NEWS file [2]
      for details.


      WHAT IS IT GOOD FOR?

      With Tahoe-LAFS, you distribute your filesystem across
      multiple servers, and even if some of the servers are
      compromised by by an attacker, the entire filesystem continues
      to work correctly, and continues to preserve your privacy and
      security. You can easily share specific files and directories
      with other people.

      In addition to the core storage system itself, volunteers have
      built other projects on top of Tahoe-LAFS and have integrated
      Tahoe-LAFS with existing systems.

      These include frontends for Windows, Macintosh, JavaScript,
      iPhone, and Android, and plugins for Hadoop, bzr, mercurial,
      duplicity, TiddlyWiki, and more. See the Related Projects page
      on the wiki [3].

      We believe that strong cryptography, Free and Open Source
      Software, erasure coding, and principled engineering practices
      make Tahoe-LAFS safer than RAID, removable drive, tape,
      on-line backup or "cloud storage" systems.

      This software is developed under test-driven development, and
      there are no known bugs or security flaws which would
      compromise confidentiality or data integrity under recommended
      use. (For all currently known issues please see the
      known_issues.txt file [4].)


      COMPATIBILITY

      This release is fully compatible with the version 1 series of
      Tahoe-LAFS. Clients from this release can write files and
      directories in the format used by clients of all versions back
      to v1.0 (which was released March 25, 2008). Clients from this
      release can read files and directories produced by clients of
      all versions since v1.0. Servers from this release can serve
      clients of all versions back to v1.0 and clients from this
      release can use servers of all versions back to v1.0.

      This is the tenth release in the version 1 series. This series
      of Tahoe-LAFS will be actively supported and maintained for
      the forseeable future, and future versions of Tahoe-LAFS will
      retain the ability to read and write files compatible with
      this series.

      "docs/quickstart.html" [7].


      HACKING AND COMMUNITY

      Please join us on the mailing list [8]. Patches are gratefully
      accepted -- the RoadMap page [9] shows the next improvements
      that we plan to make and CREDITS [10] lists the names of people
      who've contributed to the project. The Dev page [11] contains
      resources for hackers.


      SPONSORSHIP

      Tahoe-LAFS was originally developed by Allmydata, Inc., a
      provider of commercial backup services. After discontinuing
      funding of Tahoe-LAFS R&D in early 2009, they have continued
      to provide servers, bandwidth, small personal gifts as tokens
      of appreciation, and bug reports. Thank you to Allmydata,
      Inc. for their generous and public-spirited support.

      Google, Inc. is sponsoring Tahoe-LAFS development as part of
      the Google Summer of Code 2010. Google suggested that we
      should apply for the Summer of Code program, and when we did
      they generously awarded four sponsorships to students from
      around the world to hack on Tahoe-LAFS this summer. Thank you
      to Google, Inc. for their generous and public-spirited
      support.


      HACK TAHOE-LAFS!

      If you can find a security flaw in Tahoe-LAFS which is serious
      enough that feel compelled to warn our users and issue a fix,
      then we will award you with a customized t-shirts with your
      exploit printed on it and add you to the "Hack Tahoe-LAFS Hall
      Of Fame" [12].


      ACKNOWLEDGEMENTS

      This is the fifth release of Tahoe-LAFS to be created solely
      as a labor of love by volunteers. Thank you very much to the
      team of "hackers in the public interest" who make Tahoe-LAFS
      possible.
