User-Visible Changes in 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. (`#466`_)
-- The web-API has a new move operation that supports directly moving files
- between directories. (`#1579`_)
+ 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`_)
+- The web-API has a new ``relink`` operation that supports directly moving
+ files between directories. (`#1579`_)
+
+Security Improvements
+'''''''''''''''''''''
+
+- The ``introducer.furl`` for new Introducers is now unguessable. In previous
+ releases, this FURL used a predictable swissnum, allowing a network
+ eavesdropper who observes any node connecting to the Introducer to access
+ the Introducer themselves, and thus use servers or offer storage service to
+ clients (i.e. "join the grid"). In the new code, the only way to join a
+ grid is to be told the ``introducer.furl`` by someone who already knew it.
+ Note that pre-existing introducers are not changed. To force an introducer
+ 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`_)
+- 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
+ FURLs, the ``introducer`` swissnum is still displayed to show that a
+ guessable FURL is in use. (`#860`_)
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 works with recent versions of Twisted, rather than
+- 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`_)
(`#1805`_, `#1783`_)
- Exceptions no longer trigger an unhelpful crash reporter on Ubuntu 12.04
("Precise") or later. (`#1746`_)
+- Improve error message when CLI tools cannot connect to a gateway. (`#974`_)
+- Other minor changes: `#1781`_, `#1812`_
Performance Improvements
''''''''''''''''''''''''
- The flogtool utility, used to read logs, can now be accessed as
``tahoe debug flogtool`` even when foolscap is not installed system-wide.
(`#1693`_)
+- The provisioning/reliability pages were removed from the main client's web
+ interface, and moved into a standalone web-based tool in
+ misc/operations_helpers/provisioning. Use the ``run.py`` script to access
+ them.
Compatibility and Dependencies
''''''''''''''''''''''''''''''
- Python >= 2.6, except Python 3 (`#1658`_)
- Twisted >= 11.0.0 (`#1771`_)
- mock >= 0.8
+- pycryptopp >= 0.6.0 (for ed25519)

+Precautions when Upgrading
+''''''''''''''''''''''''''
+
+- When upgrading a grid from a recent version of trunk, follow the
+ precautions from this `message to the tahoe-dev mailing list`_, to ensure
+ that announcements to the Introducer are recognized after the upgrade.
+ This is not necessary when upgrading from a previous release.
