All files are signed by the Tahoe-LAFS Release-Signing Key, fingerprint
E34E 62D0 6D0E 69CF CA41 79FF BDE0 D31D 6866 6A7A. Look for detached
.asc files next to the tarballs in the directory above, as well as the
pubkey itself in a file named "tahoe-release-signing-gpg-key.asc".

This is git revision 04a3e7993f70ac87c208d61f4387a59f5f419367 on
https://github.com/tahoe-lafs/tahoe-lafs.git , which is tagged as
"tahoe-lafs-1.11.0" (with a GPG-signed tag, using the same key as
above).

Instructions for download and installation are in:

 http://tahoe-lafs.readthedocs.org/en/tahoe-lafs-1.11.0/INSTALL.html

(but it's just "pip install tahoe-lafs").

WHAT IS TAHOE-LAFS?

Tahoe-LAFS is the first distributed storage system to offer
"provider-independent security" — 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:

  http://tahoe-lafs.readthedocs.org/en/latest/about.html

The previous stable release of Tahoe-LAFS was v1.10.2, released
on July 30, 2015.

v1.11.0 overhauls the install/packaging system, bringing Tahoe
into line with standard Python practices like "pip",
"virtualenv", and "tox". It can now be installed with "pip
install tahoe-lafs". This release also includes a few small
features, like the "preferred peers" server-selection
configuration, unicode aliases, and welcome-page improvements.
See the NEWS file [1] for details.

WHAT IS IT GOOD FOR?

With Tahoe-LAFS, you distribute your data across multiple
servers. Even if some of the servers fail or are taken over
by an attacker, the entire file store continues to function
correctly, preserving 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 [2].)

COMPATIBILITY

This release should be 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.

Except for the new optional MDMF format, we have not made any
intentional compatibility changes. However we do not yet have
the test infrastructure to continuously verify that all new
versions are interoperable with previous versions. We intend
to build such an infrastructure in the future.

The new Introducer protocol added in v1.10 is backwards
compatible with older clients and introducer servers, however
some features will be unavailable when an older node is
involved. Please see docs/nodekeys.rst [14] for details.

This is the twentieth release in the version 1 series. This
series of Tahoe-LAFS will be actively supported and maintained
for the foreseeable future, and future versions of Tahoe-LAFS
will retain the ability to read and write files compatible
with this series.
