Update references to the mailing list

New list is tahoe-dev@…, list info page is at
https://lists.tahoe-lafs.org/mailman/listinfo/tahoe-dev, and list
archives are now at https://lists.tahoe-lafs.org/pipermail/tahoe-dev/.

Sadly message numbers in list archive seem to have changed, so
updating references to list archive is not as simple as prefixing
list.

1ANNOUNCING Tahoe, the Least-Authority File Store, v1.15.1
2
3The Tahoe-LAFS team is pleased to announce version 1.15.1 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:

16  https://tahoe-lafs.readthedocs.org/en/latest/about.html
17
18The previous stable release of Tahoe-LAFS was v1.15.0, released on
19January 19, 2021.
20
21In this release: PyPI does not accept uploads of packages that use
22PEP-508 version specifiers.
23
24Note that Python3 porting is underway but not yet complete in this
25release. Developers may notice python3 as new targets for certain
26tools.

28Please see ``NEWS.rst`` for a more complete list of changes.

31WHAT IS IT GOOD FOR?
32
33With Tahoe-LAFS, you distribute your data across multiple
34servers. Even if some of the servers fail or are taken over
35by an attacker, the entire file store continues to function
36correctly, preserving your privacy and security. You can
37easily share specific files and directories with other people.
38
39In addition to the core storage system itself, volunteers
40have built other projects on top of Tahoe-LAFS and have
41integrated Tahoe-LAFS with existing systems, including
42Windows, JavaScript, iPhone, Android, Hadoop, Flume, Django,
43Puppet, bzr, mercurial, perforce, duplicity, TiddlyWiki, and
44more. See the Related Projects page on the wiki [3].
45
46We believe that strong cryptography, Free and Open Source
47Software, erasure coding, and principled engineering practices
48make Tahoe-LAFS safer than RAID, removable drive, tape,
49on-line backup or cloud storage.
50
51This software is developed under test-driven development, and
52there are no known bugs or security flaws which would
53compromise confidentiality or data integrity under recommended
54use. (For all important issues that we are currently aware of
55please see the known_issues.rst file [2].)

58COMPATIBILITY
59
60This release should be compatible with the version 1 series of
61Tahoe-LAFS. Clients from this release can write files and
62directories in the format used by clients of all versions back
63to v1.0 (which was released March 25, 2008). Clients from this
64release can read files and directories produced by clients of
65all versions since v1.0.
66
67Network connections are limited by the Introducer protocol in
68use. If the Introducer is running v1.10 or v1.11, then servers
69from this release (v1.12) can serve clients of all versions
70back to v1.0 . If it is running v1.12, then they can only
71serve clients back to v1.10. Clients from this release can use
72servers back to v1.10, but not older servers.
73
74Except for the new optional MDMF format, we have not made any
75intentional compatibility changes. However we do not yet have
76the test infrastructure to continuously verify that all new
77versions are interoperable with previous versions. We intend
78to build such an infrastructure in the future.
79
80This is the twenty-first release in the version 1 series. This
81series of Tahoe-LAFS will be actively supported and maintained
82for the foreseeable future, and future versions of Tahoe-LAFS
83will retain the ability to read and write files compatible
84with this series.
