User-Visible Changes in Tahoe-LAFS
==================================
Release 1.9.0 (2011-??-??)
--------------------------
+Alpha 2 preview
+
+
+New Features
+''''''''''''
+
+- The most significant new feature in this release is MDMF, which stands
+ for "Medium Density Mutable Files". These are capable of providing more
+ efficient access and update of parts of a file. To ensure compatibility
+ with previous versions, MDMF is not yet the default format for mutable
+ files. Memory usage of a gateway when uploading and downloading MDMF
+ files may be higher than expected in this release. (`#393`_, `#1507`_)
+- 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`_)
+- 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`_)
+- 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 v1.8.2 (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
+''''''''''''''''''''''''''''''
+
+- An incompatibility of zope.interface versions 3.6.4 and 3.6.5 with Nevow
+ has been resolved. Tahoe-LAFS now requires an earlier or later version
+ of zope.interface. (`#1435`_)
+- The Twisted dependency has been raised to version 10.1. This ensures
+ that we no longer require pywin32 on Windows, that 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
+'''''''''''''
+
+- When the '--version' or '--version-and-path' options to 'tahoe' were
+ used and the version of a dependency could not be parsed, an unhelpful
+ error message would be given. (`#1355`_, `#1388`_)
+- The tahoe_files munin plugin reported an incorrect count of the number of
+ share files. (`#1391`_)
+- A ``man`` page has been added. (`#1420`_)
- Nodes now emit "None" for percentiles with higher implied precision
than the number of observations can support. Older stats gatherers
- will throw an exception if they gather stats from a new storage
- server and it sends a "None" for a percentile. (`#1392`_)
+ will throw an exception if they gather stats from a new storage server
+ and it sends a "None" for a percentile. (`#1392`_)

+
+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`_)
