      ANNOUNCING Tahoe, the Least-Authority File System, v1.8.2

      The Tahoe-LAFS team is pleased to announce the immediate
      availability of version 1.8.2 of Tahoe-LAFS, an extremely
      reliable distributed storage system. Get it here:


      Tahoe-LAFS is the first distributed storage system to offer
      "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:


      The previous stable release of Tahoe-LAFS was v1.8.1, which was
      released October 28, 2010 [1].

      v1.8.2 is a stable bugfix release, adding compatibility with
      the recently-released Twisted-10.2, and correcting a number of
      minor issues. See the NEWS file [2] for details.


      With Tahoe-LAFS, you distribute your filesystem across
      multiple servers, and even if some of the servers fail or are
      taken over 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, including
      Windows, JavaScript, iPhone, Android, Hadoop, Flume, Django,
      Puppet, bzr, mercurial, perforce, 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.

      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 important issues that we are currently aware of
      please see the known_issues.rst file [4].)


      This release is 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 thirteenth 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.

      version 2 or, at your option, any later version. See the file
      "COPYING.GPL" [5] for the terms of the GNU General Public
      License, version 2.

      You may use this package under the Transitive Grace Period
      Public Licence, version 1 or, at your option, any later
      version. (The Transitive Grace Period Public Licence has
      requirements similar to the GPL except that it allows you to
      delay for up to twelve months after you redistribute a derived
      work before releasing the source code of your derived work.)

      Transitive Grace Period Public Licence, version 1.

      (You may choose to use this package under the terms of either
      licence, at your option.)


      Tahoe-LAFS works on Linux, Mac OS X, Windows, Cygwin, Solaris,
      *BSD, and probably most other systems. Start with
      "docs/quickstart.html" [7].


      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.


      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 continued
      to provide servers, bandwidth, small personal gifts as tokens
      of appreciation, and bug reports.

      Google, Inc. sponsored Tahoe-LAFS development as part of the
      Google Summer of Code 2010. They awarded four sponsorships to
      students from around the world to hack on Tahoe-LAFS that

      Thank you to Allmydata and Google for their generous and
      public-spirited support.


      If you can find a security flaw in Tahoe-LAFS which is serious
      enough that we 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].


      This is the seventh 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
