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:
* 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).
* Add a "mkdir-p" feature to the WAPI (ticket #357).
* Many updates to the Windows installer and Windows filesystem
integration.
Filesystem v1.0, which was released March 25, 2008 [1]. This release
fixes several serious issues in Tahoe v1.0, and improves the user
interfaces. See the known_issues.txt file [2] and the NEWS file [3]
for details.
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.
COMPATIBILITY
Tahoe v1.1 is fully compatible with Tahoe v1.0. v1.1 clients produce
files which can be read by v1.0 clients. v1.1 clients can read files
produced by clients of all versions >= v0.8. v1.1 servers can serve
v1.0 clients and v1.1 clients can use v1.0 servers.

alternative than common alternatives, such as RAID, or traditional
backup onto a remote server, removable drive, or tape.
