ANNOUNCING Tahoe, the Least-Authority File System, v1.6.1
The Tahoe-LAFS team is pleased to announce the immediate
availability of version 1.6.1 of Tahoe-LAFS, an extremely
reliable distributed data store.
Tahoe-LAFS is the first cloud storage system which offers
"provider-independent security" -- meaning that not even your
cloud service provider can read or alter your data without
your consent. Here is the one-page explanation of its unique
security and fault-tolerance properties:
Tahoe-LAFS v1.6.1 is the successor to v1.6.0, which was
released February 2, 2010 . This is a bugfix release which
fixes a few small regressions in v1.6.0.
The v1.6 release includes major performance improvements,
usability improvements, and one major new feature:
deep-immutable directories (cryptographically unalterable
permanent snapshots). See the NEWS file  for details.
WHAT IS IT GOOD FOR?
With Tahoe-LAFS, you spread 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 and securely share chosen files and
directories with others.
In addition to the core storage system itself, volunteers have
developed related projects to integrate it with other
tools. These include frontends for Windows, Macintosh,
duplicity, TiddlyWiki, and more. As of v1.6, contributors have
added an Android frontend and a working read-only FUSE
frontend. See the Related Projects page on the wiki .
We believe that strong encryption, Free/Open Source Software,
erasure coding, and careful engineering practices make
Tahoe-LAFS safer than RAID, removable drive, tape, on-line
backup or other 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 normal
use. (For all currently known issues please see the
known_issues.txt file .)
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 eigth release in the version 1 series. The version
1 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 Tahoe-LAFS v1.
In addition, version 1.6 improves forward-compatibility with
planned future directory formats, allowing updates to a
directory containing both current and future links, without
loss of information.

HACKING AND COMMUNITY
Please join us on the mailing list . Patches 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 Dev page  contains
resources for hackers.
Tahoe-LAFS was originally developed thanks to the sponsorship
of Allmydata, Inc. , a provider of commercial backup
services. Allmydata founded the Tahoe-LAFS project and
contributed hardware, software, ideas, bug reports,
suggestions, demands, and they employed several Tahoe-LAFS
hackers and instructed them to spend part of their work time on
this Free Software project. Also they awarded customized
t-shirts to hackers who found security flaws in Tahoe-LAFS (see
the Hack Tahoe-LAFS Hall Of Fame ). After discontinuing
funding of Tahoe-LAFS R&D in early 2009, Allmydata, Inc. has
continued to provide servers, co-lo space, bandwidth, and small
personal gifts as tokens of appreciation. (Also they continue
to provide bug reports.) Thank you to Allmydata, Inc. for their
generous and public-spirited support.
This is the fourth release of Tahoe-LAFS to be created solely
as a labor of love by volunteers. Thank you very much to the
dedicated team of "hackers in the public interest" who make
on behalf of the Tahoe-LAFS team
