This filesystem is encrypted and distributed over multiple peers in
such a way that it continues to work correctlly even when some of the
peers are unavailable, malfunctioning, or malicious.

This is the successor to Allmydata.org "Tahoe" v0.8, which was
released February 15, 2008 [1]. This release is backwards-compatible
with v0.8.
We believe that this version of Tahoe is stable enough to rely on as a
permanent store of valuable data. The version 1 branch 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 v1.0 for the forseeable future.
This is a major release of allmydata.org "Tahoe" -- the first release
which is considered stable and functional enough to serve as a
permanent store of valuable data. New versions of Tahoe are expected
to maintain backwards compatibility with this version for the
forseeable future.
This release of allmydata.org "Tahoe" will form the basis of the next
consumer backup product from Allmydata, Inc. -- http://allmydata.com .
This release adds extensive "visibility into the grid" -- the web user
interface now shows detailed information about the nodes comprising
the grid and fine-grained statistics about the time and space used for
the storage and retrieval operations.

This is the successor to Allmydata.org "Tahoe" Least Authority
Filesystem v0.9, which was released March 13, 2008 [1]. Since v0.9
we've made the following changes:
* Added user-friendly Windows application and package, thanks
especially to Rob Kinninmont and Mike Booker (tickets #195, 242,
243, 321, 335).
* Use an added secret for convergent encryption to better protect the
confidentiality of immutable files, and remove the publically
readable hash of the plaintext (ticket #365).
* Display information about uploads and downloads (ticket #39).
* Add a "mkdir-p" feature to the WAPI (ticket #357).
* Improve performance (including tickets #304, 321).
* Many updates to the Windows installer and Windows filesystem
integration.
* Improve packaging and testing (including ticket #145).
* Add even more extensive automated tests (including ticket #207).
* Updated documentation.
Tahoe v1.0 produces files which can't be read by older versions of
Tahoe, although files produced by Tahoe >= 0.8 can be read by Tahoe
1.0. The reason that older versions of Tahoe can't read files
produced by Tahoe 1.0 is that those older versions require the file to
come with a publically-readable hash of the plaintext, but exposing
such a hash is a confidentiality leak, so Tahoe 1.0 does not do it.
WHAT IS IT GOOD FOR?
@ -61,18 +57,13 @@ malicious, the filesystem continues to work from the remaining
computers. You can also share your files with other users, using a
strongly encrypted, capability-based access control scheme.
This release is targeted at hackers and smart users who are willing to
use a web user interface, a command-line user interface, or a FUSE
interface. (Or a RESTful API. Just telnet to localhost and type HTTP
requests to get started.)
Because this software is the product of less than a year and a half of
active development, we do not categorically recommend it for the
storage of data which is extremely confidential or precious. However,
we believe that the combination of erasure coding and careful
engineering makes the use of this software a much safer alternative
than common alternatives, such as RAID or traditional backup onto a
remote hard drive, removable drive, or tape.

This software comes with extensive unit tests [2], and there are no
known security flaws which would compromise confidentiality or data
