1ANNOUNCING Tahoe, the Least-Authority File Store, v1.17.1
2
3The Tahoe-LAFS team is pleased to announce version 1.17.1 of
4Tahoe-LAFS, an extremely reliable decentralized storage
5system. Get it with "pip install tahoe-lafs", or download a
6tarball here:

10Tahoe-LAFS is the first distributed storage system to offer
11"provider-independent security" — meaning that not even the
12operators of your storage servers can read or alter your data
13without your consent. Here is the one-page explanation of its
14unique security and fault-tolerance properties:

17
18The previous stable release of Tahoe-LAFS was v1.17.0, released on
19December 6, 2021.
20
21This release fixes two Python3-releated regressions and 4 minor bugs.
22
23Please see ``NEWS.rst`` [1] for a complete list of changes.

26WHAT IS IT GOOD FOR?
27
28With Tahoe-LAFS, you distribute your data across multiple
29servers. Even if some of the servers fail or are taken over
30by an attacker, the entire file store continues to function
31correctly, preserving your privacy and security. You can
32easily share specific files and directories with other people.
33
34In addition to the core storage system itself, volunteers
35have built other projects on top of Tahoe-LAFS and have
36integrated Tahoe-LAFS with existing systems, including
37Windows, JavaScript, iPhone, Android, Hadoop, Flume, Django,
38Puppet, bzr, mercurial, perforce, duplicity, TiddlyWiki, and
39more. See the Related Projects page on the wiki [3].
40
41We believe that strong cryptography, Free and Open Source
42Software, erasure coding, and principled engineering practices
43make Tahoe-LAFS safer than RAID, removable drive, tape,
44on-line backup or cloud storage.
45
46This software is developed under test-driven development, and
47there are no known bugs or security flaws which would
48compromise confidentiality or data integrity under recommended
49use. (For all important issues that we are currently aware of
50please see the known_issues.rst file [2].)

52
53COMPATIBILITY
54
55This release should be compatible with the version 1 series of
56Tahoe-LAFS. Clients from this release can write files and
57directories in the format used by clients of all versions back
58to v1.0 (which was released March 25, 2008). Clients from this
59release can read files and directories produced by clients of
60all versions since v1.0.
61
62Network connections are limited by the Introducer protocol in use. If
63the Introducer is running v1.10 or v1.11, then servers from this
64release can serve clients of all versions back to v1.0 . If it is
65running v1.12 or higher, then they can only serve clients back to
66v1.10. Clients from this release can use servers back to v1.10, but
67not older servers.
68
69Except for the new optional MDMF format, we have not made any
70intentional compatibility changes. However we do not yet have
71the test infrastructure to continuously verify that all new
72versions are interoperable with previous versions. We intend
73to build such an infrastructure in the future.
74
75This is the twenty-second release in the version 1 series. This
76series of Tahoe-LAFS will be actively supported and maintained
77for the foreseeable future, and future versions of Tahoe-LAFS
78will retain the ability to read and write files compatible
79with this series.
