> The next release announcement will look something like this.
> DRAFT announcement for:
> ANNOUNCING allmydata.org "Tahoe", the Least-Authority Filesystem, v1.4
> The allmydata.org team is pleased to announce the release of version
> 1.4.0 of "Tahoe", the Lightweight-Authorization Filesystem. This is the
> first release of Tahoe which was created solely as a labor of love by
> volunteers -- it is no longer funded by allmydata.com (see  for
> Tahoe-LAFS is a secure, decentralized, fault-tolerant filesystem. All
> of the source code is available under Free Software, Open Source
> This filesystem is distributed over multiple peers in such a way the
> filesystem continues to operate correctly even when some of the peers
> are unavailable, malfunctioning, or malicious. Users can easily share
> files with each other, using a simple and flexible access control
> Here is the one-page explanation of Tahoe's unique security and
> fault-tolerance properties:
> This is the successor to Tahoe-LAFS v1.3, which was released February
> 13, 2009 . This is a major new release, adding garbage collection
> XXX a repairer, an efficient backup command, support for large files,
> an (S)FTP server, and much more.
> See the NEWS file  and the known_issues.txt file  for more
> Besides the Tahoe core, a crop of related projects have sprung up,
> including Tahoe frontends for Windows and Macintosh, two front-ends
> TiddlyWiki, a project to create a new backup tool, CIFS/SMB
> integration, an iPhone app, and three incomplete Tahoe frontends for
> FUSE. See the Related Projects page on the wiki: .
> Tahoe v1.4 is fully compatible with the version 1 series of Tahoe.
> Files written by v1.4 clients can be read by clients of all versions
> back to v1.0. (Unless the file is too large. Files greater than about
> 12 GiB -- depending on the configuration -- can't be read by clients of
> v1.2 or older).
> v1.4 clients can read files produced by clients of all versions since
> v1.0. v1.4 servers can serve clients of all versions back to v1.0 and
> v1.4 clients can use servers of all versions back to v1.0 (but can't
> upload large files to them).
> This is the fifth release in the version 1 series. We believe that
> this version of Tahoe is stable enough to use as a permanent store of
> valuable data. The version 1 series of Tahoe will be actively
> supported and maintained for the forseeable future, and future versions
> of Tahoe will retain the ability to read files and directories produced
> by Tahoe v1 for the forseeable future.
> The version 1 branch of Tahoe is the basis of the consumer backup
> product from Allmydata, Inc. -- http://allmydata.com .
> WHAT IS IT GOOD FOR?
> With Tahoe, you can distribute your filesystem across a set of
> computers, such that if some of the computers fail or turn out to be
> malicious, the entire filesystem continues to be available, thanks to
> the remaining computers. You can also share your files with other
> users, using a simple and flexible access control scheme.
> Because this software is new, we do not categorically recommend it as
> the sole repository of data which is extremely confidential or
> precious. However, we believe that erasure coding, strong encryption,
> Free/Open Source Software and careful engineering make Tahoe safer than
> common alternatives, such as RAID, removable drive, tape, "on-line
> storage" or "Cloud storage" systems.
> This software comes with extensive unit tests , and there are no
> known security flaws which would compromise confidentiality or data
> integrity. (For all currently known issues please see the
> known_issues.txt file .)
> This release of Tahoe is suitable for the "friendnet" use case  --
> it is easy to create a filesystem spread over the computers of you and
> your friends so that you can share disk space and files.
> You may use this package under the GNU General Public License, version
> 2 or, at your option, any later version. See the file "COPYING.GPL"
>  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 wait for up to twelve months after you
> redistribute a derived work before releasing the source code of your
> derived work.) See the file "COPYING.TGPPL.html"  for the terms of
> the Transitive Grace Period Public Licence, version 1.
> (You may choose to use this package under the terms of either licence,
> at your option.)
> Tahoe works on Linux, Mac OS X, Windows, Cygwin, and Solaris, and
> probably most other systems. Start with "docs/install.html" .
> HACKING AND COMMUNITY
> Please join us on the mailing list . Patches that extend and
> improve Tahoe are gratefully accepted -- the RoadMap page  shows
> the next improvements that we plan to make and CREDITS  lists the
> names of people who've contributed to the project. The wiki Dev page
>  contains resources for hackers.
> Tahoe was originally developed thanks to the sponsorship of Allmydata,
> Inc. , a provider of commercial backup services. Allmydata,
> Inc. created the Tahoe project, and contributed hardware, software,
> ideas, bug reports, suggestions, demands, and money (employing several
> Tahoe hackers and instructing them to spend part of their work time on
> this Free Software project). Also they awarded customized t-shirts to
> hackers who find security flaws in Tahoe (see http://hacktahoe.org ).
> Thank you to Allmydata, Inc. for their generous and public-spirited
> Zooko Wilcox-O'Hearn
> on behalf of the allmydata.org team
> Special acknowledgment goes to Brian Warner, whose superb engineering
> skills and dedication are primarily responsible for the Tahoe
> implementation, and largely responsible for the Tahoe design as well,
> not to mention most of the docs and many other things besides.
