==================================
-Release 1.10 (2013-??-??)
-'''''''''''''''''''''''''
+Release ??? (???)
+
+Compatibility and Dependency Updates
+------------------------------------
+
+Tahoe now requires Python 2.7 on all platforms. (#2445)
+
+Tahoe now requires Foolscap 0.10.1, which fixes incompatibilities with recent
+Twisted releases. (#2510, #2722, #2567)
+
+Tests should work with both Nevow 0.11 and 0.12 (#2663)
+
+Configuration Changes
+---------------------
+
+Leif's "preferred storage servers" was landed in revision 96eaca6. This adds
+"peers.preferred" to tahoe.cfg
+
+Aliases can (probably) be unicode.
+
+The introducer's "set_encoding_parameters" feature was removed.
+
+Other Fixes
+-----------

+
+Release 1.10.2 (2015-07-30)
+'''''''''''''''''''''''''''
+
+Packaging Changes
+-----------------
+
+This release no longer requires the ``mock`` library (which was previously
+used in the unit test suite). Shortly after the Tahoe-LAFS 1.10.1 release, a
+new version of ``mock`` was released (1.1.0) that proved to be incompatible
+with Tahoe's fork of setuptools, preventing Tahoe-1.10.1 from building at
+all. `#2465`_
+
+The ``tahoe --version`` output is now less likely to include scary diagnostic
+warnings that look deceptively like stack traces. `#2436`_
+
+The pyasn1 requirement was increased to >= 0.1.8.
+
+.. _`#2465`: https://tahoe-lafs.org/trac/tahoe-lafs/ticket/2465
+.. _`#2436`: https://tahoe-lafs.org/trac/tahoe-lafs/ticket/2436
+
+Other Fixes
+-----------
+
+A WebAPI ``GET`` would sometimes hang when using the HTTP Range header to
+read just part of the file. `#2459`_
+
+Using ``tahoe cp`` to copy two different files of the same name into the same
+target directory now raises an error, rather than silently overwriting one of
+them. `#2447`_
+

+
+Release 1.10.1 (2015-06-15)
+'''''''''''''''''''''''''''
+
+User Interface / Configuration Changes
+--------------------------------------
+
+The "``tahoe cp``" CLI command's ``--recursive`` option is now more predictable,
+but behaves slightly differently than before. See below for details. Tickets
+`#712`_, `#2329`_.
+
+The SFTP server can now use public-key authentication (instead of only
+password-based auth). Public keys are configured through an "account file",
+just like passwords. See docs/frontends/FTP-and-SFTP for examples of the
+format. `#1411`_
+
+The Tahoe node can now be configured to disable automatic IP-address
+detection. Using "AUTO" in tahoe.cfg [node]tub.location= (which is now the
+default) triggers autodetection. Omit "AUTO" to disable autodetection. "AUTO"
+can be combined with static addresses to e.g. use both a stable
+UPnP-configured tunneled address and a DHCP-assigned dynamic (local subnet
+only) address. See `configuration.rst`_ for details. `#754`_
+
+The web-based user interface ("WUI") Directory and Welcome pages have been
+redesigned, with improved CSS for narrow windows and more-accessible icons
+(using distinctive shapes instead of just colors). `#1931`_ `#1961`_ `#1966`_

+
+"tahoe cp" changes
+------------------
+
+The many ``cp``-like tools in the Unix world (POSIX ``/bin/cp``, the ``scp``
+provided by SSH, ``rsync``) all behave slightly differently in unusual
+circumstances, especially when copying whole directories into a target that
+may or may not already exist. The most common difference is whether the user
+is referring to the source directory as a whole, or to its contents. For
+example, should "``cp -r foodir bardir``" create a new directory named
+"``bardir/foodir``"? Or should it behave more like "``cp -r foodir/* bardir``"?
+Some tools use the presence of a trailing slash to indicate which behavior
+you want. Others ignore trailing slashes.
+
+"``tahoe cp``" is no exception to having exceptional cases. This release fixes
+some bad behavior and attempts to establish a consistent rationale for its
+behavior. The new rule is:
+
+- If the thing being copied is a directory, and it has a name (e.g. it's not
+ a raw Tahoe-LAFS directorycap), then you are referring to the directory
+ itself.
+- If the thing being copied is an unnamed directory (e.g. raw dircap or
+ alias), then you are referring to the contents.
+- Trailing slashes do not affect the behavior of the copy (although putting
+ a trailing slash on a file-like target is an error).
+- The "``-r``" (``--recursive``) flag does not affect the behavior of the
+ copy (although omitting ``-r`` when the source is a directory is an error).
+- If the target refers to something that does not yet exist:
+ - and if the source is a single file, then create a new file;
+ - otherwise, create a directory.
+
+There are two main cases where the behavior of Tahoe-LAFS v1.10.1 differs
+from that of the previous v1.10.0 release:
+
+- "``cp DIRCAP/file.txt ./local/missing``" , where "``./local``" is a
+ directory but "``./local/missing``" does not exist. The implication is
+ that you want Tahoe to create a new file named "``./local/missing``" and
+ fill it with the contents of the Tahoe-side ``DIRCAP/file.txt``. In
+ v1.10.0, a plain "``cp``" would do just this, but "``cp -r``" would do
+ "``mkdir ./local/missing``" and then create a file named
+ "``./local/missing/file.txt``". In v1.10.1, both "``cp``" and "``cp -r``"
+ create a file named "``./local/missing``".
+- "``cp -r PARENTCAP/dir ./local/missing``", where ``PARENTCAP/dir/``
+ contains "``file.txt``", and again "``./local``" is a directory but
+ "``./local/missing``" does not exist. In both v1.10.0 and v1.10.1, this
+ first does "``mkdir ./local/missing``". In v1.10.0, it would then copy
+ the contents of the source directory into the new directory, resulting
+ in "``./local/missing/file.txt``". In v1.10.1, following the new rule
+ of "a named directory source refers to the directory itself", the tool
+ creates "``./local/missing/dir/file.txt``".
+
+Compatibility and Dependency Updates
+------------------------------------
+
+Windows now requires Python 2.7. Unix/OS-X platforms can still use either
+Python 2.6 or 2.7, however this is probably the last release that will
+support 2.6 (it is no longer receiving security updates, and most OS
+distributions have switched to 2.7). Tahoe-LAFS now has the following
+dependencies:
+
+- Twisted >= 13.0.0
+- Nevow >= 0.11.1
+- foolscap >= 0.8.0
+- service-identity
+- characteristic >= 14.0.0
+- pyasn1 >= 0.1.4
+- pyasn1-modules >= 0.0.5
+
+On Windows, if pywin32 is not installed then the dependencies on Twisted
+and Nevow become:
+
+- Twisted >= 11.1.0, <= 12.1.0
+- Nevow >= 0.9.33, <= 0.10
+
+On all platforms, if pyOpenSSL >= 0.14 is installed, then it will be used,
+but if not then only pyOpenSSL >= 0.13, <= 0.13.1 will be built when directly
+invoking `setup.py build` or `setup.py install`.
+
+We strongly advise OS packagers to take the option of making a tahoe-lafs
+package depend on pyOpenSSL >= 0.14. In order for that to work, the following
+additional Python dependencies are needed:
+
+- cryptography
+- cffi >= 0.8
+- six >= 1.4.1
+- enum34
+- pycparser
+
+as well as libffi (for Debian/Ubuntu, the name of the needed OS package is
+`libffi6`).
+
+Tahoe-LAFS is now compatible with Setuptools version 8 and Pip version 6 or
+later, which should fix execution on Ubuntu 15.04 (it now tolerates PEP440
+semantics in dependency specifications). `#2354`_ `#2242`_
+
+Tahoe-LAFS now depends upon foolscap-0.8.0, which creates better private keys
+and certificates than previous versions. To benefit from the improvements
+(2048-bit RSA keys and SHA256-based certificates), you must re-generate your
+Tahoe nodes (which changes their TubIDs and FURLs). `#2400`_
+
+.. _`#2242`: https://tahoe-lafs.org/trac/tahoe-lafs/ticket/2242

+.. _`#2400`: https://tahoe-lafs.org/trac/tahoe-lafs/ticket/2400
+
+Packaging
+---------
+
+A preliminary OS-X package, named "``tahoe-lafs-VERSION-osx.pkg``", is now
+being generated. It is a standard double-clickable installer, which creates
+``/Applications/tahoe.app`` that embeds a complete runtime tree. However
+launching the ``.app`` only brings up a notice on how to run tahoe from the
+command line. A future release may turn this into a fully-fledged application
+launcher. `#182`_ `#2393`_ `#2323`_
+
+Preliminary Docker support was added. Tahoe container images may be available
+on DockerHub. `PR#165`_ `#2419`_ `#2421`_
+
+Old and obsolete Debian packaging tools have been removed. `#2282`_

+Release 1.10.0 (2013-05-01)
+'''''''''''''''''''''''''''
New Features
------------
- The Welcome page has been redesigned. This is a preview of the design style
that is likely to be used in other parts of the WUI in future Tahoe-LAFS
versions. (`#1713`_, `#1457`_, `#1735`_)
-- A new, more extensible Introducer protocol has been added, to act as the
- basis for future improvements such as accounting. Compatibility with older
- nodes is not affected. When server, introducer, and client are all
- upgraded, the welcome page will show node IDs that start with "v0-" instead
- of the old tubid. (`#466`_)

files between directories. (`#1579`_)
to generate a new FURL, delete the existing ``introducer.furl`` file and
restart it. After doing this, the ``[client]introducer.furl`` setting of
every client and server that should connect to that introducer must be
- updated. (`#1802`_)
+ updated. Note that other users of a shared machine may be able to read
+ ``introducer.furl`` from your ``tahoe.cfg`` file unless you configure the
+ file permissions to prevent them. (`#1802`_)
- Both ``introducer.furl`` and ``helper.furl`` are now censored from the
Welcome page, to prevent users of your gateway from learning enough to
create gateway nodes of their own. For existing guessable introducer
Notable Bugfixes
----------------
-- If an immutable file failed to download, e.g. due to a connection problem,
- subsequent attempts to download the same file could also fail. (`#1679`_)
-- The SFTP frontend now works with recent versions of Twisted, rather than
- giving errors or warnings about use of ``IFinishableConsumer``. (`#1926`_,
- `#1564`_, `#1525`_)
-- Failure handling in the SFTP frontend has been improved. (`#1525`_)
-- Checking a LIT file using ``tahoe check`` no longer results in an
- exception. (`#1758`_)
+- In earlier versions, if a connection problem caused a download failure for
+ an immutable file, subsequent attempts to download the same file could also
+ fail. This is now fixed. (`#1679`_)
- Filenames in WUI directory pages are now displayed correctly when they
contain characters that require HTML escaping. (`#1143`_)
- Non-ASCII node nicknames no longer cause WUI errors. (`#1298`_)
-- Error messages containing tracebacks may be slightly more readable.
- (`#1484`_)
-- ``tahoe cp --verbose`` counts the files being processed correctly.
