User-Visible Changes in Tahoe-LAFS
==================================
-* Release 1.8.2 (2011-01-30)
+Release 1.9.0 (2011-??-??)
+--------------------------
+
+Alpha 2 preview
+
+
+New Features
+''''''''''''
+
+- The most significant new feature in this release is MDMF: "Medium-size
+ Distributed Mutable Files". Unlike standard SDMF files, these provide
+ efficient partial-access (reading and modifying small portions of the file
+ instead of the whole thing). MDMF is opt-in (it is not yet the default
+ format for mutable files), both to ensure compatibility with previous
+ versions, and because the algorithm does not yet meet memory-usage goals.
+ (`#393`_, `#1507`_)
+- A "blacklist" feature allows blocking access to specific files through
+ a particular gateway. See the "Access Blacklist" section of
+ `<docs/configuration.rst>`_ for more details. (`#1425`_)
+- A "drop-upload" feature has been added, which allows you to upload
+ files to a Tahoe-LAFS directory just by writing them to a local
+ directory. This feature is experimental and should not be relied on
+ to store the only copy of valuable data. It is currently available
+ only on Linux. See `<docs/frontends/drop-upload.rst>`_ for documentation.
+ (`#1429`_)
+- The timeline of immutable downloads can be viewed using a zoomable and
+ pannable JavaScript-based visualization. This is accessed using the
+ 'timeline' link on the File Download Status page for the download, which
+ can be reached from the Recent Uploads and Downloads page.
+
+Configuration/Behavior Changes
+''''''''''''''''''''''''''''''
+
+- Prior to Tahoe-LAFS v1.3, the configuration of some node options could
+ be specified using individual config files rather than via ``tahoe.cfg``.
+ These files now cause an error if present. (`#1385`_)
+- Storage servers now calculate their remaining space based on the filesystem
+ containing the ``storage/shares/`` directory. Previously they looked at the
+ filesystem containing the ``storage/`` directory. This allows
+ ``storage/shares/``, rather than ``storage/``, to be a mount point or a
+ symlink pointing to another filesystem. (`#1384`_)
+- ``tahoe cp xyz MUTABLE`` will modify the existing mutable file instead of
+ creating a new one. (`#1304`_)
+- The button for unlinking a file from its directory on a WUI directory
+ listing is now labelled "unlink" rather than "del". (`#1104`_)
+
+Notable Bugfixes
+''''''''''''''''
+
+- The security bugfix for the vulnerability allowing deletion of shares,
+ detailed in the news for v1.8.3 below, is also included in this
+ release. (`#1528`_)
+- Some cases of immutable upload, for example using the ``tahoe put`` and
+ ``tahoe cp`` commands or SFTP, did not appear in the history of Recent
+ Uploads and Downloads. (`#1079`_)
+- The memory footprint of the verifier has been reduced by serializing
+ block fetches. (`#1395`_)
+- Large immutable downloads are now a little faster than in v1.8.3 (about
+ 5% on a fast network). (`#1268`_)
+
+Packaging Changes
+'''''''''''''''''
+
+- The files related to Debian packaging have been removed from the Tahoe
+ source tree, since they are now maintained as part of the official
+ Debian packages. (`#1454`_)
+- The unmaintained FUSE plugins were removed from the source tree. See
+ ``docs/frontends/FTP-and-SFTP.rst`` for how to mount a Tahoe filesystem on
+ Unix via sshfs. (`#1409`_)
+- The Tahoe licenses now give explicit permission to combine Tahoe-LAFS
+ with code distributed under the following additional open-source licenses
+ (any version of each):
+
+ * Academic Free License
+ * Apple Public Source License
+ * BitTorrent Open Source License
+ * Lucent Public License
+ * Jabber Open Source License
+ * Common Development and Distribution License
+ * Microsoft Public License
+ * Microsoft Reciprocal License
+ * Sun Industry Standards Source License
+ * Open Software License
+
+Compatibility and Dependencies
+''''''''''''''''''''''''''''''
+
+- To resolve an incompatibility between Nevow and zope.interface (versions
+ 3.6.3 and 3.6.4), Tahoe-LAFS now requires an earlier or later
+ version of zope.interface. (`#1435`_)
+- The Twisted dependency has been raised to version 10.1 to ensure we no
+ longer require pywin32 on Windows, the new drop-upload feature has the
+ required support from Twisted on Linux, and that it is never necessary to
+ patch Twisted in order to use the FTP frontend. (`#1274`_, `#1429`_,
+ `#1438`_)
+- An explicit dependency on pyOpenSSL has been added, replacing the indirect
+ dependency via the "secure_connections" option of foolscap. (`#1383`_)
+
+Minor Changes
+'''''''''''''
+
+- A ``man`` page has been added (`#1420`_). All other docs are in ReST
+ format.
+- The ``tahoe_files`` munin plugin reported an incorrect count of the number
+ of share files. (`#1391`_)
+- Minor documentation updates: #627, #1104, #1225, #1297, #1342, #1404
+- Other minor changes: #636, #1355, #1363, #1366, #1388, #1392, #1412, #1344,
+ #1347, #1359, #1389, #1441, #1442, #1446, #1474, #1503

+Release 1.8.3 (2011-09-13)
+--------------------------
+
+Security-related Bugfix
+'''''''''''''''''''''''
+
+- Fix flaw that would allow a person who knows a storage index of a file to
+ delete shares of that file. (`#1528`_)
+- Remove corner cases in mutable file bounds management which could expose
+ extra lease info or old share data (from prior versions of the mutable
+ file) if someone with write authority to that mutable file exercised these
+ corner cases in a way that no actual Tahoe-LAFS client does. (Probably not
+ exploitable.) (`#1528`_)
