Announcements and News

Tahoe-LAFS v1.9.0 Beta 1 Released
- ---------------------------------

Tahoe-LAFS proudly released `1.9.0 beta 1`_.  Below are the changes between
beta 1 and alpha2:

 * CLI: use "tahoe put --format=MDMF" to create an MDMF file, instead of
   "tahoe put --mutable --mutable-type=MDMF"
 * web: WUI now has a three-item radiobox (CHK, SDMF, MDMF) instead of
   the tricky one-togglebutton+two-item-radiobox combination
 * web-API t=JSON output now emits upper-case "format: MDMF" instead of
   lower-case "mutable-type: mdmf"
 * MDMF filecaps no longer include the extra two "extension fields"
   (containing 'k' and segsize), and tolerate (ignore) arbitrary
   extension fields from the future

The beta is available `here`_ in tar.gz, tar.bz2, zip and -SUMO variants.
You can also fetch it via any of our fine version control systems:

  darcs get --lazy --tag=allmydata-tahoe-1.9.0b1 \
  http://tahoe-lafs.org/source/tahoe-lafs/trunk tahoe-lafs-1.9.0b1


  git clone -b allmydata-tahoe-1.9.0b1 git://github.com/warner/tahoe-lafs.git

or, if you already have a git checkout:

  git pull
  git checkout allmydata-tahoe-1.9.0b1

The following items remaining for a final release:

 * docs
 * packaging tests
 * test against the new Foolscap release, 0.6.2, also current Twisted trunk

Please download the beta and test it out.  Our hope is to release 1.9.0 at
the end of this month.

Foolscap 0.6.2 Release
- ----------------------

Brian |brian| released Foolscap `0.6.2`_.  This release fixes an
incompatibility with the current Twisted trunk, which will cause problems
when the next Twisted release comes out.  The previous Foolscap would only
work with Twisted 11.0.  This would cause issues for Tahoe-LAFS 1.9.0, which
has dependencies on both pieces of software.  The new release supports both
Twisted 11.0 and the current Twisted trunk.

Commercial Supporter of the Week

The Commercial Support of the Week is Least Authority Enterprises (LAE).  LAE
is working on bringing *freedom-compatible* storage to the end user.  *Freedom
compatible* storage means you can take advantage of online service providers
while still retaining control over your data.  LAE's first product is
Tahoe-LAFS on S3.  You can watch their progress in ticket `999`_ as they to
enable Tahoe-LAFS support for multiple backends, not just S3.

LAE also employs three Tahoe-LAFS developers: Zooko |zooko|, David-Sarah
|davidsarah| and Josh Wilcox |wilcox|.

- From the tahoe-dev Mailing List
- ------------------------

Brian announced `Accounting 11.10`_.  This tracks who uses what space.  It
will allow grids to stop offering space once a user exceeds their quota.
Eventually, this could be expanded to incorporate Bitcoin.  A user once
they exceeded their quota could buy additional space through Bitcoin.
Accounting offers full backwards compatibility with introducers which don't
support accounting.  Below are instructions how to test it:

1. install http://github.com/warner/python-ed25519
2. git clone -b accounting https://github.com/warner/tahoe-lafs.git
3. cd tahoe-lafs
4. start a grid with this version (you want a new Introducer, client, and servers)

Tahoe-LAFS Logo
- ---------------

Zooko provided a post to the list regarding the `logo`_ for Tahoe-LAFS.  We
would like to have a few shirts with the logo for the next `Summit`_.  Ticket
`1185`_ covers the current candidates for the logo.  Please post your
thoughts regarding the designs to this ticket.  Also if you are interested in
updating the web site to the new logo and printing the tshirts, please let
Zooko know.

Patch Needing Review of the Week

There are three (3) tickets still needing review for 1.9:

* 393_: MDMF

Let's see if we can't get these reviewed and 1.9 out the door.
